I upgraded the CPU's on my Mac Pro 5,1 and used a "normal/cheap" thermal paste and the machine did run significantly hotter afterwards. It got much better after reapplying a better thermal paste. (In my case the Thermal Grizzly Kryonaut with 12.50W/m K) Definitely worth a try.
Redo these tests with custom fan curves. I did that recently and my MacBook Pro will turbo up to 3.3 all cores now. Which is pretty good considering I've never replaced the thermal paste. Thank you Luke and definitely interested in your next video.

I changed the thermal paste on the mid 2012 MacBook Pro I just got and it was horrible how little paste was on there to begin with. It was a huge preformance boost.
I just changed my macbook late 2013 model thermal paste as well. There is definitely a difference. Temp was rising way faster before applying and now its better. Also I think cleaning service really helped as well.
Yes, it does. But only if you spread the thermal paste with Apple's titanium credit card. Of course, the more you granted credit, the more conductivity.
i have change the thermal paste of my very old macbook(11 years old)(macbook 4.1) and this is what i noticed: with no thermal paste on youtube: fan goes to 6200rpm(max) with new thermal paste: 4200 rpm (more quiet) for a very old macbook it's very good :)
Thermal paste will often get better after a few thermal cycles. I'd recheck the stats after 3 or 4 cycles before coming to a conclusion.The biggest benefit is that the CPU / GPU won't thermal throttle, so you will actually get better performance.

I just did this yesterday and pretty much noticed the same things aside from performance differences. They were pretty much the same afterwards for me. I also more did this for maintenance reasons and not performance reasons. I’m looking to try and get at least another 3 years out of my mid 2015 15” MBP before I’m forced to buy a new one. The dust build up in mine wasn’t all that bad though the fans were pretty caked. I also found a couple dead spiders in mine so that was fun lol.
When I got my Late 2013 15” maxed MBP about few weeks ago, I repasted it immediately. After opening it up it was so full of dust like wtf I can’t even explain how much there was dust. I did tests and on idle before repasting/dusting it was running at 80°C on idle... dusted it, repasted with the trusty old Arctic MX-4. Got a 10°C drop on temperatures and saw huge improvements in overall performance.
Whenever I’m about to do anything even mildly taxing on my MacBook, I open up fan control and crank those boys up to 6900 rpm and it sounds like it’s going to lift off the desk, lol
4 years later, still never disassembled, the difference is massive. Cleaning and repasting 2012-2015 MBPs, I usually get 10-15C lower idle temps and going from throttling within 10 secs in a Cinebench run to staying under 95 the entire time. And that is on Apples fan curve!! I do use Kryonaut or similar rather soft high performing paste, so it will need to be repasted again more often.
hello, i have a couple of MBP2011 i just fixed (demux) and dusted. I Wanted to know if a repaste would be worth it. there are old machine i'm affraid to damage some of the plugs while doing it. You recommand testing under Cinebench ? I guess if it throttles too fast i'll change it.
It's only really wort it, if you are going to actually use them, and you have fan noise bothering you. On the pre 2013 models you have to remove the logic board because the cpu/heat-pipe is facing up against keyboard. Especially the zif connectors and the display connector can be a bit of a hassle. @@mcronfpv8736
Just put new paste on my mid 2012 retina. Noticeable difference running 4k YT videos and other easy tasks on the computer. Worth the job! Using this computer for everday tasks still doing a great so!!
I have a 2011 Macbook Pro, the thermal paste has never been changed. I am very tempted to change the thermal paste, as after almost 10 years, it probably is almost non existent, idle temps are about 70C...heats up to about 95-100 degrees at load.
Quick observation on numbers before and after re-paste. There was one extra variable introduced. Dirty fans / heat sinks. Luke cleaned the fans / heat sinks at the same time that he did the re-paste. This makes it harder to determine how much of the new cooling effects were due to the re-pasting vs. just cleaning the heat sinks. All that being said, I am sure that re-pasting DID HELP. But I would suggest re-doing the experiment again in a year or two when the thermal paste needs to be replaced this time getting new "before" numbers after a heat sink cleaning and then again after another re-pasting. That way the heat sink cleanliness variable is eliminated.
You say the paste they use from the factory is crap, but there's actually a really good reason why they use what they do. It has really low viscosity. You can leave it in there for 20 years, and it'll perform like it did day one. With pastes like what you use in this video you'l need to change it after a year to maintain optimal performance; Decreasing more and more over time. The real issue with the thermal system is actually the texture of the heatsink. It's not smooth enough to perfectly connect the CPU/Paste to all the surface of the heatsink. Too many pits that the paste can't fill in. Your paste helps fill those gaps, but with the aforementioned disadvantage.
Greetings, Mr. Luke Miani. I have a macbook pro 15" 2018, model A1990, with i9 processor and touchbar. Model known for being very hot and not delivering the expected performance of the i9! I want to replace the thermal paste, but I'm in doubt about which thermal paste I should use, to better cool the i9 and not need to change the thermal paste every year. I would like to know which thermal paste do you recommend? If you can make a video where you compare the best thermal pastes for Macbooks Pro. I think it will be of great help to many who like and learn a lot from your videos.
Why didn’t you take normal thermal grease? Why did not take MX4? Weren't you able to buy it? Who will put the cheapest thermal grease in a laptop with a price in a car?
My Late 2013 13" was hitting 90C+ on a few tabs in chrome. I opened it up and removed all the dust - opened the fan and removed all the fine dust here too. Replaced the thermal paste and added thick thermal pads on top of the heatsink above the CPU, along the headline, and across the grill. Running 50-60C in chrome now, idling around 45C wow. Add thermal pads!
If you monitor the hardware with windows in bootcamp and modify the boost with throttlestop you'll get a much clearer picture of how effective repasting the CPU and GPU can be. The reason why is because the MacBook pro in macOS will just run at very mild frequency and power settings because they've set up the software to never push the hardware very hard. When you start tweaking things in boot camp, with windows 10 you can really see where performance gains can be made.
I repasted my entry level 15 inch MacBook Pro 2015 with thermal grizzly kryonaut and even in Cinebench it will barely come over 90 degrees, with max fans running not over 82 degrees. Now it runs with an linear turbo boost speed of 3.0 GHz, and the machine thermally throttled before with the standard thermal paste. So I can totally recommend the Kryonaut Thermal Paste!
I know I’m late on this, cause this video is old, but hear me out. It’s important to know that not all thermal pastes are the same. Some respond to certain CPUs and GPUs differently, some have different compositions that react differently to desktop CPUs (with heatspreaders) and laptop CPUs (without heatspreader). I have noticed that for CPU’s without a heatspreader, IC Diamond Thermal Compound works quite well. I have a similar computer to this one (MBP 2015 15”) and I used MX4 on it. It performs well the first couple of weeks, but it starts sucking given time. On the other hand, when I used IC Diamond, that never happened, the performance got better and it stayed better. So... thank you for coming to my Ted Talk, I accept tips.
I wonder if idle speeds is the more important result? I’d be willing to bet our computers run at the those speeds at least 70% of the time. So a ten degrees difference goes towards the performance of the computer of a longer period of time.
I refurbish Windows machines laptops and anytime I can easily access the CPU to change the paste, I do. Most of the time it isn't a huge difference, but sometimes, on certain ultrabooks, it makes all the difference.
I have a 2014 15" MBP retina that has been running constantly as a Keyshot Render Farm node to the point that it's battery got swollen. We've finally gotten a proper render farm server, so I'm taking it down, replacing the battery (thanks iFixit, only $89) and replacing the thermal paste bc this thing has been running HOT for literally years.
Just repasted an old late 2013 MBP and it is measurably better. The old paste did not cover the whole chip. Used cinebench, geek bench and my favourite game to test. It really did make a difference. Idles about 8 degrees cooler and (you should monitor this) noticed the fan speeds were almost 2000 rpm cooler doing similar tasks.
In my 2009 unibody the paste was gummy and hard after many years of gaming with it and the fans were spinning hard even when looking at youtube, after giving it new paste it was noticeable better. with my MacBook Pro 2012 there was no noticeable difference. Your right about the the fan curves, that's just the way Apple sees the user experience ! Programs that lets you manually adjust the fan speeds are "not supported" ;) Great video Luke !
You not only used poor thermal pasted, likely put too much on as well but also you re tested too soon! Thermal paste can take many hours of use before it reaches peak effectiveness... we talking 30% difference so it was worth waiting for.
I'll agree with the fan/cpu theory. My refurbished 2018 Mac Mini tended to run high temperatures before I ever heard the fan kick on. I ended up buying some external USB fans to help cool it down, and it cut the temperatures significantly. Not sure if I should worry about it or not though since it's under warranty and I don't know if the high temps are the norm with the 2018 Mac Minis since they claim they have a better cooling system.
Preventative maintenance performed annually. Not using battery power, a can of compressed air, a tiny circular brush for the fan blades and one screw driver bit for the MacBook Pro cover screws is all you need to keep the cooling fans and the CPU connecting duct clean enough to keep "almost" everyone cool and happy.
Long story short, YES, it does improve performance. Dont go cheap on the thermal compound. Like and suscribe to Luke so that the next video tittle isnt just a question, but he answer too
gee - i'm reading your comments and i still havent understood which are the expensive & best pastes to use. And nor if getting a better one is a good thing after all. Can someone explain simply and also provide a list of the best ones that exist. Thanks!
I would stick with Thermal Grizzly Kryonaut. It's the best non conductive paste you can get. Arctic MX-4 is pretty close too. Liquid metal performs better but if you make a mistake it will be a very expensive one! I didn't find this video helpful at all.
thanks for confirming my experiences. I've tried the liguid metal types even with PC.c. Conclusion. Thermal paste...the costly stuff...is a waste. Good tutorial.
@@akpokemon my opinion? I don't really think so. Not significantly. But I haven't done any in depth studies. I have never had a CPU fail. Not once since 1986 when I got my first pc.
I generally install SMC Fan Control no matter what. I couldn't care less if my laptop is 'noisy'. I'd rather have the heat out of there quickly and for as long as possible.
Biggest problem with Imac's is heat build up from the hard drive & display . Two ways of reducing or removing heat 1) install a ssd this takes out the heat. 2) after 10 yrs the thermal becomes less effective. Also all pastes are not the same, the thermal conducive rates vary. Does it effect performance ?, not really it effects reliability more which in some ways does impact performance.
Absolutely love my Late 2013 MacBook Pro Retina. Ive changed out the thermal paste, and using TG Pro. The app has a setting: Temporary increase fans when needed to keep cpu limit at least __% to avoid throttling. (You decide what percentage to use). It's not perfect, but the app does it's best to deliver. Don't laugh, but when I'm doing some intensive work, I have a one of those 'lap desks' that tilts up, leaving a space in the base. I pop a 12 hour thermal ice pack in that space. (Since it's in an open air environment, you'll get about 90 minutes to 2 hours cool time.
I had a problem where my computer was overloading on Logic Pro x and it didn’t usually do that especially with how little the project was. Do you thinking adding thermal paste and general maintenance will fix it and make it run good again?
I don't have any fancy tests but I bought the $15.00 thermal paste from Best Buy and I can say with certainty it has made a big difference in how hot it gets just sitting on my lap watching UA-cam videos.
my Macbook pro late 2013 does 1404 points on cinebench r20. For me it made a huge difference. Before I changed the thermal paste my CPU was running at 1,8 GHz when I was rendering something. Now its at 2,6-2,8 GHz. I can only recommend changing the thermal paste
Arctic silver 5, not the best nor the worst, but for a Mac I would suggest getting some liquid metal tbh. Frankly, Apple undervolt the cpu heavily already and runs the fans as slow as possible without cooking the cpu for the sake of quiet. Thermal paste shouldn’t matter too much. But if you need you mac at the max for long period of time, extra fan curve and liquid metal is a good option.
If you want to deal with the poor fan curves on Mac, there is a one really good fan utility that I use(I forget the name) that lets you alter fan curves or just run them on full blast continously
My 2009 Macbook Pro is freezing the picture for about 10 seconds, while the sound continues to play as I am running UA-cam. The fans are no longer speeding up like they used to when the computer was new. Q - What do I do to fix this?
My late 2013 retina Dual GPU model runs at 73 Celsius & 74 Celsius on max load with MX4 thermal paste. They must of changed it with software updates. Mine never gets too hot even under load.
Um…the mirrored surface you’re seeing is where the thermal paste was pulled off of the chip. It’s not an indication of where the paste wasn’t covering the chip. You’re really misrepresenting things there.
I just put some MX4 in my 2017 Macbook Air. OMG, I wish i would have done it sooner. There was no thermal paste on the GPU from the factory. Dropped my idle from 60C to 45C and now the integrated GPU has come to life from 350MHz, to full 1GHz. With my Istat menus, I have noticed an increase my CPU clock speeds as well. Luke is right though, the fans will not kick on until 90C. Using Macs fan control will allow you to create your own fan speed curve, i recommend it because I like a cool mac on my lap when I type and has the side effect of making your $1000+ macbook alive longer.!
Question for Luke Miani what u got against the MacBook Air I own one personally it’s been a good lightweight Mac for me since I gave my 2008 MacBook Pro to my 13 yr old niece
Luke, aren’t you concerned that the keyboard backlight is flickering? A few years ago, I had a 2008 MacBook Pro and I experienced the keyboard backlight flicker.
I used MX4 paste on a used 2013 MacBook Air not long ago. While it didn't turn it into a raging powerhouse, the fans don't turn on as often so I know it's running more efficiently. The factory paste was bad like the one in the video. I still think it's worth doing.
I have a 2012 macbook pro that always ran hot. I ran across a video by snazzylabs about thermal paste so i tried changing it for the first time last week. I didn't really believe the hype but after applying mx4 its like a whole new macbook. It runs super quiet now, so quiet that i had to download mac fan control to make sure my fan was still working. I was actually planning on upgrading my mac bc i thought the reason for it running so hot was because it wasnt sufficient enough to handle macos anymore smh. Im not upgrading anytime soon now!
The reason that the score is lower is because that the temperature is sampled at the heater sink. By re-pasting, you improve the heater transfer, therefore the system will measure the target temperature quicker than before re-pasting, therefore the fan kicks in and cools the temperature, at the same time the system might be slowed down a little bit to maintain the temperature. On the other hand, without re-pasting, it takes longer for the system to kicks in to cool down the system, meaning the CPU runs longer at highest speed. As a result, the score is a little bit down, but the cpu temperature is lower by 10 degrees.
I didn't keep my temps so I can't remember what they were, but my Cinebench score went from 1320's to 1450's, my fan vents were kinda dirty too so it may have just been that
I'm using a graphite pad on the same 2013 15inch model and it can turbo to 3.2 under sustained load with fan at max using macs fan control and I think it's worthy to change the thermal interface
I still have a late 2013 here. I used it daily for about 4 years, and what turned me down was the CPU fan going like crazy every now & then. Then I went the cheap & easy way, with old Thinkpads (t430 right now), and I don't have this issue. I might however repaste, just to see how it feels. i keep the laptop as a spare...
My macbook 2017 15 inch won’t get even warm unless i try to play a game such as Minecraft......with in 30 seconds it will get hot.....i’m not sure how hot? just in the middle near the screen.....it’s pretty hot. should i worry about it or just play the game?
I have Macbook Pro 15" Retina, Late 2013, 16gb RAM, 500GB SSD. I've been experiencing problems as my Mac keeps shutting down by itself whenever hot. However, the problem goes away when I use my AC unit as eventually the environment becomes cool. Will changing the thermal paste help my case?
Replaced the thermal paste of my Macboook Pro late 2013 13 inch. Still love it! won't replace it in 3 years after Apple replace the keyboard for an decent one :).
in my MacBook Air late 2017 the CPU temperature reaches 90 degrees Celsius and more from just watching UA-cam videos so I will definitely change the thermo paste
hey luke like, i reflowed my imac 2011 27" gpu and replaced the thermal paste on the cpu and gpu...it went great and i made the machine come back to life but now the cpu is locked at 1,60ghz ...if i put it to sleep when it comes back the cpu works faster but after a few seconds it goes back to 1,60ghz... it may be some cable thats ruined but i think it may be a firmware thing where apple makes the speed lock and u gotta change something on the firware...im not sure ...can you help?
Yeah, cleaning out the dust, looking for corrosion, seeing if any spiders made their home inside the computer, or crumbs etc. always good. New thermal paste every now and then, good with that too.
still very high idle, my 2018 macbook pro 15 inch idles at 32c. Also cinebench r20 is very inconsistent, i think they need to fix it, for some reason after a change in hardware or software it throws lower numbers and then a day later and many rund later it chucks out numbers that are correct and it does it consistently after.
Someone should just make a fan/heatsink upgrade for the MBP. Something that removes a lot more heat. Faster airflow, larger heat tubes. Heat tubes are that expensive, and they could make the fans 20% larger or something.
I just changed the thermal paste, and battery and cleaned my entire a1990 (macbook pro 15" mid 2018). The conclusion is that my experience is worst than before x)

With pastes like what you use in this video you'l need to change it after a year to maintain optimal performance; Decreasing more and more over time. The real issue with the thermal system is actually the texture of the heatsink. It's not smooth enough to perfectly connect the CPU/Paste to all the surface of the heatsink. Too many pits that the paste can't fill in. Your paste helps fill those gaps, but with the aforementioned disadvantage.
spot on !
Wow good to know
Casper S� that's it! Thats why my 13 years old Mac Pro still performs!
Guy makes a video about changing the thermal paste... and doesn't record when he changes thermal paste. Good video!
I liked the video anyway cause I've learn many thing. Thanks for sharing!
Greetings, Mr. Luke Miani.
I have a macbook pro 15" 2018, model A1990, with i9 processor and touchbar.
Model known for being very hot and not delivering the expected performance of the i9!
I want to replace the thermal paste, but I'm in doubt about which thermal paste I should use, to better cool the i9 and not need to change the thermal paste every year.
I would like to know which thermal paste do you recommend?
If you can make a video where you compare the best thermal pastes for Macbooks Pro. I think it will be of great help to many who like and learn a lot from your videos.
Why didn’t you take normal thermal grease? Why did not take MX4? Weren't you able to buy it? Who will put the cheapest thermal grease in a laptop with a price in a car?
So noob test we see. I don’t expect from so smart guy, this fuckup.
My Late 2013 13" was hitting 90C+ on a few tabs in chrome. I opened it up and removed all the dust - opened the fan and removed all the fine dust here too. Replaced the thermal paste and added thick thermal pads on top of the heatsink above the CPU, along the headline, and across the grill. Running 50-60C in chrome now, idling around 45C wow. Add thermal pads!
Does the bottom panel get hot with this steup?
If you monitor the hardware with windows in bootcamp and modify the boost with throttlestop you'll get a much clearer picture of how effective repasting the CPU and GPU can be. The reason why is because the MacBook pro in macOS will just run at very mild frequency and power settings because they've set up the software to never push the hardware very hard. When you start tweaking things in boot camp, with windows 10 you can really see where performance gains can be made.
I repasted my entry level 15 inch MacBook Pro 2015 with thermal grizzly kryonaut and even in Cinebench it will barely come over 90 degrees, with max fans running not over 82 degrees. Now it runs with an linear turbo boost speed of 3.0 GHz, and the machine thermally throttled before with the standard thermal paste. So I can totally recommend the Kryonaut Thermal Paste!
Yeah Idk if something else changed but I changed the thermal paste using arctic mx4 and my Cinabench score went from 1300 to 2009 shit was fire.
I know I’m late on this, cause this video is old, but hear me out. It’s important to know that not all thermal pastes are the same. Some respond to certain CPUs and GPUs differently, some have different compositions that react differently to desktop CPUs (with heatspreaders) and laptop CPUs (without heatspreader). I have noticed that for CPU’s without a heatspreader, IC Diamond Thermal Compound works quite well. I have a similar computer to this one (MBP 2015 15”) and I used MX4 on it. It performs well the first couple of weeks, but it starts sucking given time. On the other hand, when I used IC Diamond, that never happened, the performance got better and it stayed better.
So... thank you for coming to my Ted Talk, I accept tips.
Oh yeah, I’ve also seen people that have had the same experience on the 2018 Mac Mini, cause it also has a CPU without a heatspreader.
I wonder if idle speeds is the more important result? I’d be willing to bet our computers run at the those speeds at least 70% of the time. So a ten degrees difference goes towards the performance of the computer of a longer period of time.
We need some charts, to visualize the differences better ;) bring them back 🥺
I refurbish Windows machines laptops and anytime I can easily access the CPU to change the paste, I do. Most of the time it isn't a huge difference, but sometimes, on certain ultrabooks, it makes all the difference.
1:46 is it me or does it sound like a creeper explosion here? Or have I been watching too much MC lately
THEFIRE360 ....LOL YEP creamer is near...
I have a 2014 15" MBP retina that has been running constantly as a Keyshot Render Farm node to the point that it's battery got swollen. We've finally gotten a proper render farm server, so I'm taking it down, replacing the battery (thanks iFixit, only $89) and replacing the thermal paste bc this thing has been running HOT for literally years.
Just repasted an old late 2013 MBP and it is measurably better. The old paste did not cover the whole chip. Used cinebench, geek bench and my favourite game to test. It really did make a difference. Idles about 8 degrees cooler and (you should monitor this) noticed the fan speeds were almost 2000 rpm cooler doing similar tasks.
Who’s here before he changed it to paste
Me 🤣🤣🤣
Seems like i am one of those :D
Here
??? What?
Me
I literally just did this 2 days ago. I got about a 10-15% improvement using MX-4!
exactly, if you're going to repaste, at least put something with good quality, not simply generic, there's a real difference
@@XInfinity2024 For sure. My thermals still were at 100 C while running R20, but my scores went from 1087 to 1196.
In my 2009 unibody the paste was gummy and hard after many years of gaming with it and the fans were spinning hard even when looking at youtube, after giving it new paste it was noticeable better. with my MacBook Pro 2012 there was no noticeable difference. Your right about the the fan curves, that's just the way Apple sees the user experience ! Programs that lets you manually adjust the fan speeds are "not supported" ;)
Great video Luke !
You not only used poor thermal pasted, likely put too much on as well but also you re tested too soon! Thermal paste can take many hours of use before it reaches peak effectiveness... we talking 30% difference so it was worth waiting for.
I'll agree with the fan/cpu theory. My refurbished 2018 Mac Mini tended to run high temperatures before I ever heard the fan kick on. I ended up buying some external USB fans to help cool it down, and it cut the temperatures significantly. Not sure if I should worry about it or not though since it's under warranty and I don't know if the high temps are the norm with the 2018 Mac Minis since they claim they have a better cooling system.
I don't buy it, the fan is blowing into the heat sink to cool it, your fan is hitting the body which does not even touch the heat sink.
Preventative maintenance performed annually. Not using battery power, a can of compressed air, a tiny circular brush for the fan blades and one screw driver bit for the MacBook Pro cover screws is all you need to keep the cooling fans and the CPU connecting duct clean enough to keep "almost" everyone cool and happy.
I was repasting my MacBook Air 2013 because of old past and also clean out the dust now my Mac runs better less fan noise and overheat.
Long story short, YES, it does improve performance. Dont go cheap on the thermal compound. Like and suscribe to Luke so that the next video tittle isnt just a question, but he answer too
gee - i'm reading your comments and i still havent understood which are the expensive & best pastes to use. And nor if getting a better one is a good thing after all. Can someone explain simply and also provide a list of the best ones that exist. Thanks!
I would stick with Thermal Grizzly Kryonaut. It's the best non conductive paste you can get. Arctic MX-4 is pretty close too. Liquid metal performs better but if you make a mistake it will be a very expensive one! I didn't find this video helpful at all.
thanks for confirming my experiences. I've tried the liguid metal types even with PC.c. Conclusion. Thermal paste...the costly stuff...is a waste. Good tutorial.
uh, so....did the liquid metal help??????
@@akpokemon my opinion? I don't really think so. Not significantly. But I haven't done any in depth studies. I have never had a CPU fail. Not once since 1986 when I got my first pc.
Wait thermal past?
I generally install SMC Fan Control no matter what. I couldn't care less if my laptop is 'noisy'. I'd rather have the heat out of there quickly and for as long as possible.
Same!
Massive improvement of the performance on my MacBook Pro mid 2015
my old 2012 MBP fell down from 20 degrees. Now I can use it as was intended, a laptop to be used on your lap.
Biggest problem with Imac's is heat build up from the hard drive & display .
Two ways of reducing or removing heat 1) install a ssd this takes out the heat.
2) after 10 yrs the thermal becomes less effective. Also all pastes are not the same, the thermal conducive rates vary.
Does it effect performance ?, not really it effects reliability more which in some ways does impact performance.
Absolutely love my Late 2013 MacBook Pro Retina. Ive changed out the thermal paste, and using TG Pro. The app has a setting: Temporary increase fans when needed to keep cpu limit at least __% to avoid throttling. (You decide what percentage to use). It's not perfect, but the app does it's best to deliver.
Don't laugh, but when I'm doing some intensive work, I have a one of those 'lap desks' that tilts up, leaving a space in the base. I pop a 12 hour thermal ice pack in that space. (Since it's in an open air environment, you'll get about 90 minutes to 2 hours cool time.
I had a problem where my computer was overloading on Logic Pro x and it didn’t usually do that especially with how little the project was. Do you thinking adding thermal paste and general maintenance will fix it and make it run good again?
Wish you would've done a second round of tests with Mac Fan Control.
I don't have any fancy tests but I bought the $15.00 thermal paste from Best Buy and I can say with certainty it has made a big difference in how hot it gets just sitting on my lap watching UA-cam videos.
good video but I wanted to see how much should I apply to it.
my Macbook pro late 2013 does 1404 points on cinebench r20. For me it made a huge difference. Before I changed the thermal paste my CPU was running at 1,8 GHz when I was rendering something. Now its at 2,6-2,8 GHz. I can only recommend changing the thermal paste
Arctic silver 5, not the best nor the worst, but for a Mac I would suggest getting some liquid metal tbh.
Frankly, Apple undervolt the cpu heavily already and runs the fans as slow as possible without cooking the cpu for the sake of quiet. Thermal paste shouldn’t matter too much. But if you need you mac at the max for long period of time, extra fan curve and liquid metal is a good option.
If you want to deal with the poor fan curves on Mac, there is a one really good fan utility that I use(I forget the name) that lets you alter fan curves or just run them on full blast continously
Istat menu
Mac fans control
Also smc fan control
My 2009 Macbook Pro is freezing the picture for about 10 seconds, while the sound continues to play as I am running UA-cam.
The fans are no longer speeding up like they used to when the computer was new.
Q - What do I do to fix this?
My late 2013 retina Dual GPU model runs at 73 Celsius & 74 Celsius on max load with MX4 thermal paste. They must of changed it with software updates. Mine never gets too hot even under load.
I always modify the fan curve for better cooling, trying to find a happy medium between fan noise and cooling.
Um…the mirrored surface you’re seeing is where the thermal paste was pulled off of the chip. It’s not an indication of where the paste wasn’t covering the chip. You’re really misrepresenting things there.
I just put some MX4 in my 2017 Macbook Air. OMG, I wish i would have done it sooner. There was no thermal paste on the GPU from the factory. Dropped my idle from 60C to 45C and now the integrated GPU has come to life from 350MHz, to full 1GHz. With my Istat menus, I have noticed an increase my CPU clock speeds as well. Luke is right though, the fans will not kick on until 90C. Using Macs fan control will allow you to create your own fan speed curve, i recommend it because I like a cool mac on my lap when I type and has the side effect of making your $1000+ macbook alive longer.!
Question for Luke Miani what u got against the MacBook Air I own one personally it’s been a good lightweight Mac for me since I gave my 2008 MacBook Pro to my 13 yr old niece
Luke, aren’t you concerned that the keyboard backlight is flickering? A few years ago, I had a 2008 MacBook Pro and I experienced the keyboard backlight flicker.
I used MX4 paste on a used 2013 MacBook Air not long ago. While it didn't turn it into a raging powerhouse, the fans don't turn on as often so I know it's running more efficiently. The factory paste was bad like the one in the video. I still think it's worth doing.
What are you using after disabling the cover? exactly in minute 1:55
if the temp is not lower and performance is not better, then I suppose the fan niose is much quieter. So please do a fan noise comparison.
I have a 2012 macbook pro that always ran hot. I ran across a video by snazzylabs about thermal paste so i tried changing it for the first time last week. I didn't really believe the hype but after applying mx4 its like a whole new macbook. It runs super quiet now, so quiet that i had to download mac fan control to make sure my fan was still working. I was actually planning on upgrading my mac bc i thought the reason for it running so hot was because it wasnt sufficient enough to handle macos anymore smh. Im not upgrading anytime soon now!
The reason that the score is lower is because that the temperature is sampled at the heater sink. By re-pasting, you improve the heater transfer, therefore the system will measure the target temperature quicker than before re-pasting, therefore the fan kicks in and cools the temperature, at the same time the system might be slowed down a little bit to maintain the temperature. On the other hand, without re-pasting, it takes longer for the system to kicks in to cool down the system, meaning the CPU runs longer at highest speed. As a result, the score is a little bit down, but the cpu temperature is lower by 10 degrees.
Thermal Paste* fix it Luke 😭😭😭
Lol
Let him have his opinion
I didn't keep my temps so I can't remember what they were, but my Cinebench score went from 1320's to 1450's, my fan vents were kinda dirty too so it may have just been that
I'm using a graphite pad on the same 2013 15inch model and it can turbo to 3.2 under sustained load with fan at max using macs fan control and I think it's worthy to change the thermal interface
I still have a late 2013 here. I used it daily for about 4 years, and what turned me down was the CPU fan going like crazy every now & then. Then I went the cheap & easy way, with old Thinkpads (t430 right now), and I don't have this issue. I might however repaste, just to see how it feels. i keep the laptop as a spare...
I have 2015 MBP lying around! Will do this and report here!
How much is a difference between using a premium paste, like Grizzly, vs nothing at all?
My macbook 2017 15 inch won’t get even warm unless i try to play a game such as Minecraft......with in 30 seconds it will get hot.....i’m not sure how hot? just in the middle near the screen.....it’s pretty hot. should i worry about it or just play the game?
I have Macbook Pro 15" Retina, Late 2013, 16gb RAM, 500GB SSD. I've been experiencing problems as my Mac keeps shutting down by itself whenever hot. However, the problem goes away when I use my AC unit as eventually the environment becomes cool.
Will changing the thermal paste help my case?
I guess your problem is the battery.
Hi Bro
What should I do?
I change or not?
Replaced the thermal paste of my Macboook Pro late 2013 13 inch. Still love it! won't replace it in 3 years after Apple replace the keyboard for an decent one :).
in my MacBook Air late 2017 the CPU temperature reaches 90 degrees Celsius and more from just watching UA-cam videos so I will definitely change the thermo paste
Is there a video that shows how to change the thermal paste on a mac? I don't know how to remove the old paste
It's not just about fans being quiet, it's about conserving the battery too.
hey luke like, i reflowed my imac 2011 27" gpu and replaced the thermal paste on the cpu and gpu...it went great and i made the machine come back to life but now the cpu is locked at 1,60ghz ...if i put it to sleep when it comes back the cpu works faster but after a few seconds it goes back to 1,60ghz... it may be some cable thats ruined but i think it may be a firmware thing where apple makes the speed lock and u gotta change something on the firware...im not sure ...can you help?
Yeah, cleaning out the dust, looking for corrosion, seeing if any spiders made their home inside the computer, or crumbs etc. always good. New thermal paste every now and then, good with that too.
Is there better quality paste and would it make a difference?
switching from had to ssd lowered my temp 3 degrees I'm happy
still very high idle, my 2018 macbook pro 15 inch idles at 32c. Also cinebench r20 is very inconsistent, i think they need to fix it, for some reason after a change in hardware or software it throws lower numbers and then a day later and many rund later it chucks out numbers that are correct and it does it consistently after.
What about thermal pads instead of thermal paste?
Would you recommend the thermal grizzly pads for example?
Someone should just make a fan/heatsink upgrade for the MBP. Something that removes a lot more heat. Faster airflow, larger heat tubes. Heat tubes are that expensive, and they could make the fans 20% larger or something.
Lol this is actually what ive been working on. Its crazy no one makes mbp mods
So you’re saying I should download that app that lets me control the fan speed
Can you hack the fans to get better performance?
I just changed the thermal paste, and battery and cleaned my entire a1990 (macbook pro 15" mid 2018). The conclusion is that my experience is worst than before x)
I’d rather have better performance over a noisy fan. I don’t like how it throttles when I’m trying to work
But if you don't change it then it dries and doesn't cool down the heat.
What’s the best thermal paste to use in this instance?
MX4
Does he mean fahrenheit nor celcius cuz last i checked 50°C at idle is dangerous and 90°C is almost boiling for water
lol it's Celsius, computers run hot. 50C idle for a laptop is normal.
112°F im guessing he means inside not outside then
@@alexprospal8548 yes computer Temps are measured on or near the gpu or cpu chips
@@alexprospal8548, 50ºC is 122ºF.
