#VRM #ASUS #Z390
Bottom line: Load temperature dropped by over 30°C just by adding a tiny little 40mm fan onto the heat sink.
So that's why my ROG Z390-E came with a VRM heatsink fan mount and 40mm fan. I did install it but I didn't think it would actually be that useful.
If your worried about VRM thermals - pull the blingy plastic IO guards off - 2-3 screws and it frees up the entire top/back of the VRM heat sink for airflow. Did that on my Z390-E and it never goes over 60C without the included 40mm installed. Running a DH15 with the middle fan mounted low as it can go - lots of air flows to that area.
@@OrBy00 Did the same thing on my Z370-E and running the same cooler. Can't get VRM temps in HWinfo but just feeling the bare heatsink, theres quite a bit of difference.
Something loose:
Zip tie it!
why not if it works, Do it, Do it.
how do you attach it? you make some measurement's. fire up fusion 360 design something and 3D print it.
oo I guess my case air flow made this a non issue for me. never had any kind of vrm temp issues on my z390
Yes this. I was using a cheap ass case. Didn't realize how much of a factor that contributes towards cooling.
Half my fans are held on by bread ties xp
my z370 gaming f came with a Fan Bracket for VRM tha screw in to a mobo screw and you can put a 40 or 50mm fan
You are aware that ASUS Prime Z390-A has a fan stand that you can put a 40mm or 50mm on in, right?
where?
@@ducklover7423
Upper left corner.
There's a small stand in the box.
@@gabis1963 yea i thanks i alr installed a fan tho
Arctic Liquid Freezer II has 40mm VRM fan built in. I wonder if it's as effective.
I use double side tape and call it a day.
I have a 140mm fan on top of my case, above vrms. I recommend to do the same if you worry about your vrm temps. I have a b450 tuf gaming plus(not a great board) and a ryzen 7 3700x. Eco mode and stock settings keeps everything cool.
What 40 mm fan did you use?
This video is gold. I will get a fan for VRM cooling and have my MOBO going for a very long time, if needed. Very nice to expand hardware life, don't ever need my hardware to die.
In my daily rig I have a 92mm fan that I mount above the socket area using a couple of small L shaped brackets on top case fan mounts, gives some airflow to the memory as well.
Hello there
Damn you E A R L Y
Was this on an open bench? How many people run their systems on an open bench? Can you replicate this in a normal case use scenario with non-radiated and non-obstructed intake blowing at the board?
I have this mobo, but with only an I7-8700 the highest I have seen is 42°C VRM temp so I don't think I need to do worry about it, the benefits of a simple tower air cooler.
This vid popped up in my recomended section after 2 months using the 5600g on my GA A320M S2H. My old cpu was the Athlon 3000g and yeah having a good fan as active vrm cooling helps alot and yes I did some tweaking like disabling Turbo and keep it at base clock.Its running very well and Im happy.Although I dont know why the 5600g runs cooler than the Athlon 3000g even with Fan vrm cooling.
ty man for improvising with zip ties and not having to use screws that Asus did "NOT" include also did not include the tiny fan, just that dam Bracket, with "NO" screws they were not kind enough to Include "ZIP TIES" like you suggested Asus can at times be ButtHeads. well won't be Extremely OC'ing but did want to Clock it to least 4.7 or 8 wonder if I will still need the Tiny Fan ??? for a 4.7 OC ?
Do you need 2 fans for 2 section (heatsinks) pf the VRM...? One can only cool one section heatsink right...? Or is only one heatsink overheating and the other one is OK ? (so you need to cool only one heatsink/VRM section)?
A CPU cooler that blows air downwards will actually cool the VRMs too, that's why this problem occurs with AIOs and tower based heatsinks. That's why my top mounted radiator is set to pull air into the case and out the back fan so that there's decent airflow over the VRMs.
Sure, but no such cooler exists that would allow running a 9900K at 5.1GHz/1.35v.
i have seen a fan mount that comes with the motherboard, could you tell me if is that for, i have a 9600k but i want to know in case i put in the future a 9900k there
I have a stupid plastic io cover over my
Vrm heat sink. Is it ok to remove that plastic? I have a mini noctua fan I want to add but those covers block the heat sinks.
I went back through your videos and noticed you hadn't ever done a video on the EVGA Z270 Classified K motherboard. I'm about to build a pc using it and I'd love to see your opinion, review, and/or tear down of it. Always thoroughly enjoy your indepth views on equipment!
so is this asus z390 okey with i9 9900k even tho i may or maynot plan on oveclocking?
Saw your geil mems on ebay, was tempted.
Do you think the VRM fan on the Arctic Liquid Freezer II is sufficient for cooling a VRM?
Absolutely not-it is a mere gimmick, JUST good enough to show some improvement on reviewers' temp charts, but not good enough to make any real world difference. I am running an i7-10700k on an Asrock Z490 phantom gaming 4/ax motherboard with the Arctic Liquid Freezer II 280, and while the ALF is easily outperforming the Grand Macho RT (which outperforms the Noctua NH-D15S), the system settles out at a paltry 140w continuous on the CPU due to VRM throttling! I have tried both with and without its VRM fan, and noticed no appreciable difference. Meanwhile, the Macho can do ~190w and the Noctua ~150w continuous on the same system, both topping out with CPU thermal throttling. It looks like the ALF could easily do >225w if the VRM stayed cool, but without that CPU "underflow" air from an air cooler, the VRM cooks. Case fans barely help; the air needs to be high-speed directly across the tiny VRM heatsinks, something that the oversized Macho and Noctua fans (which blow over the top and under the bottom of the heatsink) do very well.
I have this mainboard, but the VRM Temp. doesnt show up in HWinfo. (I have enabled Asus EC)
Use AIDA64
@@gabis1963 ...That advice doesn't speak to the problem that we are having. WHY doesn't it appear for the both of us in the program but it does for Buildzoid? We need the answer to that...not to install another program.
@@Rickbearcat It does appear in HWInfo but you need to enable it. Don't know why it's not on by default.
@@gabis1963 ...Enable it? Why? Do you see how much stuff is already enabled in the pane? Tons and tons of stuff. Why is not ONE LINE of info not enabled in the EC tab when there are 200+ data points listed?! Can you tell me exactly how to enable the VRM data point?
In the Sensor Status window right click and select "Layout Settings..."
In the setting go to [ASUS EC] and enable monitoring for VRM
You can disable what ever you don't want to see and even remove it from showing by un-check "Show"
Ahem...you mean 2 Tweezers...
yep, its why watercooling solution are bad for VRM. (except the latest artic freezer one which has a working fan for the VRM, you should test it)
by the way...
did you have solutions to cool down the backplate of the CPU?
which is hot when running for long time.
I plan to put some small heatsinks and a slim fan on top of them.
@UCDN0XL4mE2wLHRtQsKjyLHQ the VRM are using heatsinks by default, not a backplate.
and I'm curious to know if he already did this type of setup and if there is a real improvement or not.
a fan without a heatsink, not sure if it will have a effect.
@@willgart1 Of course fan without a heatsink will have an effect. If you blow air at literally anything, you're gonna remove heat from it.
@@PaulHawke1337 yep, but its less effective.
else we'll not need a heatsink on top of a CPU.
the heatsink get the heat quickly from the hot source, and increase the area in contact with the air, increasing the performance of the cooling setup.
well... I have to find a small low profile fan first. I think noctua has some available.
You sound like Andrew Tate
Or you can just set your top fans as Intake
I have a dark rock pro that takes up all that space.
My 2x 120mm top fans blow down over the VRM and RAM and I still think I want to include the VRM in my waterloop, just need to find the right baseplate for Watercool.de VRM blocks, for Asus Z370-E Gaming.
IIRC Asus has 3D prints for download on their site. I think I should also mount that Corsair RAM cooler again that came with my RAM, LoL.
Cooling is vital, no doubt.
And yeah, Asus is going south, for some years now. Even their most expensive stuff lacks behind in terms of craftsmanship and reliability.
My msi z390 pro carbon ac with a 9900k running at 4700mhz all cores doesnt seem to get over 66c with cb20 avx offset off and here i was worrying about it pre purchase. Normal gaming use it barely hit 50c. Then again i use a dual fan aircooler. So i guess this problem mainly is a AIO problem.
Isn't there a 40mm or so fan mounting in the Asus Prime box itself? Maybe it's meant for the M2 but you can use the motherboard screw that's in the VRM corner.
A 'fan holder'/bracket is included but not a fan.
@@amharris The discussion was about "how to fit it" not about "how to find a 40mm/50mm fan"
@@zzmadd Just re-read your original comment. I must've been tired, as I was sure I read "Isn't there a 40mm fan in the [...] box?"
My bad. 🙃
Would you recommend a coffee modded Maximus IX Apex for 9900k for daily use? Because I'm thinking about building my new rig and I already have a z170 platform so upgrades will be easier (because I don't have to buy everything at once) and I can buy new apex for like 210 USD that's why I'm asking
I was curious about how to actively cool the VRM and the chipsets. didnt know if these little fans would make a loud whirring sound and some might. but I know they have some quiet ones out there.. a couple of ideas and notes Id add to this however.
for making a bracket this sort of thing is where I shine. you can go as simple as making a bent wire brace out of stiff bailing wire which you could even slide the mounting holes onto then you can make the bracket hold onto something on the back side of the case. then you have the 3D printer option, making sure to use material that is heat resistant... you dont want it to droop.. you can sketch up the base design on poster-board stock then take measurements. then there is another method of taking thin aluminum or tin sheets bending and punching/drilling/dremil small holes where needed. then paint afterwards with some cheap "heat resistant" krylon spray paint.
also in cases with air cooling I would make sure to push air from bottom up as you are likely to have fans pulling air in that direction and you wouldn't want to fight that wind current, you could stagnate the air and create more of a problem. even with an AIO I might do this to keep with flow direction. this will also direct all heat up and out or out the back of the case giving you a better ambient inside the case, meaning ALL your temps will be lower.
I'm so past having a quiet system, I'm using 6 Corsair HD 120mm fans @1900RPM & a HD140mm @1500RPM. plus my aorus extreme's fans at max or around 2800RPM , only time I ever turn them down is at before bed when not gaming anymore xD
also did buildzoid say I could ziptie a fan around the heat pipes of my air cooler?!??? yeah like that won't melt lol
My Hardware Info screen does not show me the VRM temperatures under the Asus EC tab. Do you know why this is and how I can get the program to show it? I have an Asus Maximus Hero IX.
can the asus prime z370-a handle an OCd i9-9000k if there's a 40/50 mm fan mounted on the VRM? What stable frequency can it reach before destroying the mobo?
I got the A520M and the VRMs over heat way too fast. They get 120 deg C after a couple minutes of rendering and my render speed starts dropping.
i've attached a 40mm fan to it using one of the motherboard screw holes and a series of the brass screwy studs. basically another simple way to do it.

i cut the small heatsink myself. don't bother me about all the dust and "aesthetics", i don't give a damn.
I've been wanting to see if changing the vrm thermal pads, with better thermal pads or ic graphite or thermal paste and then add a fan, but look like that not necessary. How did this influence your overclock frequency and performance?? Was there any improvements??? Great job again
Watching your cpu-z,brings to mind another topic,cpu constant/fixed/manual voltage(call it what you will), versus the offset or adaptive. Does the manual voltage degrade the CPU overtime? Like some people think.. I've seen various videos where you talk about voltages,but never about this specific thing.
Also if you use air tower cooler instead of aio (something like dark Rock pro 4, noctua nh d15s to run i9 around 5ghz) due to circution of air Flow around main board it Will reduce vrm temps but ofc not that much.
Hey BZ, nice content. I love these little useful tidbits you throw you post from time to time..........Also, I never noticed how long and slender (Dainty?) your wrists and and hands were until now....LOL
Fans = good? Who knew?!
they make a bracket for it
Depending on memory you might hook zipties on heatsinks.
On on the clips if you're a mad man
those hyperx look like a ziptie might fit in one of those ... grooves? If so put an exact spacer between the ram and ziptie yourself a ram sticks-spacer-fan-unit. :)
How does this compare to the the rear 120mm fans found in every case?
best video on youtube
cooler upgrade!.
Do you have to take the vrm cover off before securing the fan? Please and thank you
For attaching fans to memory I suggest strong double-sided tape (I usually use the kind that keeps picture frames stuck to walls) or good old Blu Tack when zip ties are too awkward.
Doesn't this motherboard come with a bracket for doing this?
BZ won't fix our boards for money but he does it for Asus for free lol
Velcro is actually the best way to secure fans and also works very well for vibration reduction.
U could 3D print a bracket to fix the fan to the heatsink
A drop of super glue in 2-3 corners is what I use.
How would I go about enabling the ec temp sensors on a gigabyte board?
Sure, fixing a fan can help but the fundamental problem here, as with most cases is that CPU cooler mounted at the top. You're trying to cool the CPU with (100C!) hot air coming from the VRMs, GPU and RAM. The result is a hot CPU, hot radiator with loud fans. The whole area at the top of the case just gets hotter and hotter.
The optimal solution is a front mounted radiator for the CPU, pulling in cold air. At the top, just an exhaust fan. This will help all that hot air from the VRMs, GPU and RAM to escape.
I have a 140mm fan mounter on the hdd cage via L shaped bracket used for closets etc. It blows fresh air. My case is open I never had vrm temp issue
ASUS stuff gets worse and worse and worse and worse.
And what does my little eye spy? A cap mod on the GPU? ;)
Wouldn't the heatsink melt these zip-ties?
good
Would a 40mm fan or 50mm fan be better?
GREAT idea, I've been concerned with the temps on the TUF x570 gaming (don't laugh) Chipset. They get as high as 80 oC while gaming. The Ryzen 5 3600X CPU (stock air cooler) is ok at 60 oC (max) . Actually I was considering buying a small AC unit to pump cold air in the intake fans, to cool the entire PC ... but a few extra fans might be alot cheaper.
pumping AC into running systems tends to create condensation and kill stuff.
@@ActuallyHardcoreOverclocking yeah, I was planning to filter for moisture. but a small fan on the chipset should do ?
Zip ties and hot glue ftw
Quick question: can mosfets be too Cold for their load? With a custom loop with a Monoblock on my Aorus X470 Gaming 7, the VRM sensor never gets above 40C (according to HWinfo)
technically most parts aren't specced to work bellow -55C. but good luck reaching that temp
@@ActuallyHardcoreOverclocking yeah, lol, that's never going to happen. Have no ambitions of putting my Ryzen on D-Ice or liquid Nitrogen, which may put it close to that spec. Maybe play around with a Gigabyte GTX460SEv1 I have at some point, or a Alienware OEM GTX 280 1.8GB card I have, but that's it
you realize people have airflow IN their cases BUiLLDY? not everyone is using a testbench
The VRM's should not be getting that hot in the first place. Some VRM's just have an inadequate cooling solution to begin with.
Tell that to all the X470 boards I tested that run 110-120C in cases with 4 fans. The corner of the mobo where the VRM is normally an airflow dead zone because there's memory sticks and CPU heatsinks blocking any airflow.
I have the exact same issue with my Aorus Z370 Ultra gaming Wifi w/ an 8700k Clocked at 4.8 all core || Daily use and gaming it is totally fine, however I do 3D Art as a career and when I occasionally render in Arnold (a CPU render) my VRM gets really hot. When stress testing it can hit 100+ degrees.
I just bought a 40mm fan and will try this fix, will let you know how it goes. Thank you for the video
How did it go?
Sorry for the very late comment here
@@andrexskin It did help a little, in my case it lowered my temps by 10 degrees or so.
@@DavieBoy531 Better than nothing! Thank you for the infos and I hope your career is going very good!
I'm thinking of doing that to my x570 taichi. Its tiny fan is so loud, but the temps don't get low even with high rpms.
kousaka san On my X570 Taichi I have made a custom fan curve for the chipset fan. It does not turn on until the chipset reaches 65C. The good news is thanks to the airflow from my case fans and GPU never let it reach that point. My VRM temperatures never go over 45C when running a 3900X.
@@stevenbradford6138 I have good airflow. but 2080 ti sits right over the board. I that's why I could use a larger fan blowing in from the side
Very informative, thank you.
My vrm run between 25 idle and 35-45 (winter/summer) with full load prime 95. It hurts to see 110° :c
Are you water cooling it or are the sensors broken?
@@ActuallyHardcoreOverclocking Ek monoblock for X470 Taichi on them.
I think i killed my first X370 Pro carbon when i switched to full watercooling loop with no airflow (7-800rpm fan fixed, big rads, big case), didn't mind them and it just died (the mobo, the 2700x is fine) while trying some oc configs. I was dumb, i didn't knew you at the time and i didn't tought about VRM temps or the airflow.
The airflow is so low that i had to put an ek heatsink even on the NVME SSD (it is a 970 evo, not a newer one with the heatsink already installed on it) because he went throttling (summer here is hot 30-35°) while videoediting and stuff, reached 87-90° degrees on one sensor and around 60 on the other. I didn't realize why the encoding time was so shitty until i looked at the drive's temps.
At the time i was dumber and thought the only two things that need airflow were CPU and GPU. That's how i found you, while looking for the new mobo one year ago c:
Thank you for your work and dedication.
just
get
creative

I'm pretty sure the temp is fine in a case with normal airflow, a test bench with a watercooled cpu is worst case scenario i would think
the VRM area of a motherboard tends to be a complete airflow dead zone. Which is also why when I did in case VRM testing most low end motherboards still overheat unless you do something weird like run your rear fans as intake.
@@ActuallyHardcoreOverclocking Its weird. while stress testing with prime95, 9700k@5ghz 1.3V VRM temp never went above 70C. and another question is msi z390i gamiing would overclock better than this board or no?
You are a life saver

Where do I get the cheap little fan
Any PC hardware store that sells desktop components such as cases and fans will have them. Electric component stores only have industrial ones that are to loud.
Go for the Noctua fan. They're quiet and reliable. There's a 3 pin, a 4 pin, and a 5v fan, so just make sure you get the right one for your application.

As a tinkerer of many junk, I often shudder at the thought of zip ties never being invented.
Making proper brackets for every damned project would probably made me into someone who buys imacs for msrp and think I'm techy and cool.
