25:04 in my experience that's true, in fact I have the opposite problem with my new laptop that I just bought... it seems like laptop manufacturers now don't put any limit on how fast the fans spin, they are spinning at max too often, which causes mechanical problems since the parts are not capable of operating at max speed for long periods of time like that... because of this my fan will die prematurely and the laptop rendered unusable, when a simple RPM limit would fix everything... planned obsolescence at play again...
one of the sensors has abnormal reading, hence why the fan is high. usually, when you have a failed sensor then the CPU usage will be slightly higher in task manager. look like a damaged resistor shown at 10:03 just below the large cap
Fan spinning at full speed sometimes may be caused by damaged BIOS (ME-REGION) happend with My laptop ;) That fix required a BIOS reprogramming This (Yours) solution is way cool :) :) Thanks! Keep up the good work!
I that case i cut the red wire, and solder 2 diodes in serial. Each have about 0.7V drop, so with 2 the voltage is dripping to 3.6V and the speed of the fan is good. But i use regular ones and just isolate them :) And also, not all the diodes have that voltage drop.
I just got my Dell E6530 replacement fan working with some inspiration from you. Original fan was working but noisy and vibrated the laptop. I bought a replacement fan, didn't work, company replaced it and the 2nd didn't work either. Put the replacement fan on the bench to see how I could get it to spin and found if I shorted the red and blue together it would spin. Tried that in the laptop and it now runs. Not sure what that means but it's working. Can anyone explain the logic behind my fix? I think the replacement fan wasn't the same even though it looked nearly identical. Thanks for the great videos! So many great tips.

Nice job but: What if CPU needs more air flow and get overheated then shut down? I think that the PWM (Pulse Wide Modulation) signal is suffering a distorted filtering due to a shorted capacitor : in this case only "high duty ratio" pulses are allowed to pass across the remaining working capacitors which means full RPM 100% of the time...
Hi Sorin, I am French. I've got a DELL inspiron and it wake up on leds and screen but the Fan don't spin. The screen lights but no pictures. I changed fan but no way it doesn't spin. This laptop had fallen before this but nothing seems to be desoldering or broken. Question please : is Super I/O responsive or bios or other thing ? How it works ? Who's his master ? you don't speak about this there in your video. Thanks a lot.
Hi electronics superman...i just want ask is all laptop are the same mosfet use?..let say i will get mosfet from dell laptop and use in asus laptop?..thanks for the reply. Have a nice day.
Hi.Can You tell in few words what can cause - fan working normally and stopped working after dissasembly.Checked all sables,plugs etc... Laptop switch off itself after start (1-2s) without fan spinning.I know fan is ok as it started to work again after it was not working...and now not working again.
hi sorin just a question i was wondering, will the fan turn faster when the processor gets hot? is it dangerous like to damage the processor when he gest hot ? thanks before you answer
Sorin some time back you published a link to Ilinca Antonescu's channel, my daughter visits her channel regularly and finds it great, Ilincas stuck on 788 subscribers for ages so would be nice to republish the link and see if we can get her up to 1000 or over, what do you think?
@WannaDIY Yeah, troll, the western way (our throw away society) is to say, "Sorry, it's not worth repairing....But I can repair it for $$$, but you'll have to wait for the parts to come in". Sometimes people just want their laptop working again. They don't want to spend $$$$ and wait for parts to come in.
im just wonder...if one of the temperature sensor is shoted, can be NTC thermothing that means vith a higher temperature decreases the resistivity and the controller chip means it is too hot and starting cool down with the fan. but when the termistor is shorted the controller can not receive a good 'temperature(resistivity)' sensing that will be react on wrong inputs, it can be the issue with fast spinning fan. in the board is written PTC43**, easily can be chechked when we are putting some heat to area. and i think these termistors are pulled up and that why we dont see a big current. wellcome from Hungary! you have nice videos
Nothing dodgy about that Sorin, sometimes you have to improvise and thats something you do very well, I think you should change your name to McGyver, lol, keep up the good work.
oh really?? is this really true?? what the "experts" are saying?? huh? can you answer me instead of ignoring me?? because I think you guys are full of shit 🤣🤣🤣 have you ever did experiments like that yourself? do you have video footage to proove it for example? I think you don't
@@Customer22374rt so you suggest to lower the whole system performance but not fix the original issue or just leave the fan as is at full blast :D that's sounds ridiculous
i guess it's far harder to find 3 equal resistors on a spare board than 3 equal diodes. And in case of resistors you have to check what wattage they can handle and what voltage drop results in them. It's far easier and time saving using diodes.
i want to know if anyone had a repair on a xbox the old one and if there is a video of it as i got one as it is now on oragne and it works a bit then turns off by it self :) and i dont know what to do
8:50 how the heck can he cut these small wires so seamlessly? when I try cutting small wires like that I always end up cutting them instead of simply cutting the cover out, I have too heavy hands... these small wires give me anxiety LOL Electrician hands? Is that a thing? LOL
why not find a low volt rail and line it from there with a bridge wire thats wot i would do :) but the slow switching diode in series is still a nice fix bro .. i love ur videos
One time I had opened my laptop to fix the noisy fan. I took out the fan cleaned it and it was ok but when I started the laptop it showed me an error msg like fan error and the fan was spinning at max. RPM. Opened the laptop again and figured out that connection was not right. Adjusted the connector and it worked fine
Wjy cant you just use a lower rating resistor,I mean it sure can get heated up,but not that much to explode or melt...It would drop the rpm by maybe 10-15%,why use diodes?I know that in other direction the diode gives higher resistance than in other direction..but yet...
Dodgy indeed! Remind me not to buy my used laptops at your shop! ;-) What happens when the graphics chip is taxed so much that it really NEEDS the extra cooling from the fan on high? It gets too hot and eventually dies quicker than necessary. And that's fine if it's your own machine and you plan to replace it sooner or later...
@@electronicsrepairschool yes it is, In bios use quite fan if not fan runs at full speed. When starting computer fan runs at full speed for 2 seconds then returns to quite fan if set in bios. Is this not software?
what will happen when the lucky customer who buys this laptop will, for example, play some demanding games ? guessing some thermal shutdown due to the fan deliverately stuck at low speed which leads to insufficient cooling …
that's exactly what I just wrote... what he says is true, that's not as much as a big problem as it seems... coupled with some underclocking and undervolting you can play games just fine, in fact not any loss in performance for 10 to 15 Celsius temperatures lower than before, at no performance cost... pretty great... besides that, these CPU's have to tools to adapt if needed
as someone who ran an older laptop that didn't have a cooling fan for 4 years and that just bought a new one (having more issues with the newer one than the older one...) Trust me, my experience says everything is okay in this case.... Matter of fact, I would say these measures he implemented will INCREASE the lifespan of the cooling fan, it will work for a much longer time spinning a bit slower
Sorin, thanks for all your efforts. With my very little experience in repairing/preparing laptops (couple of years), i would find this solution a bit risky under high load. But if you say it wil be fine then i accept that. Please don't get disappointed from some doggy comments, If somebody don't like your videos/methods then get the f@#k out of here. Please go on...
this is embarrassing to the repair community.. I mean it might work, but not to spec. Were it an atom processor, fine, those even work with a coin on top as heat sink, but this has a dedicated video card! Not to mention no heat shrink or other type o isolation of the leads on the diodes... I usually love your work, but this... no words...
Not doggy at all, I'm still a beginner and I never fix a laptop. When CPU gets too hot, obviously the fan must run at a high speed which will require 5v.
the fan doesn't cool the processor in a direct way, it cools down the heatsink by airflowing the laptop. That fan is not on top of that processor or do i miss something?..

Blue wire on the fan is PWM and when PWM not present the fan will spin at full speed, so actually PWM line is missing on the fan connector.....
u r right
At 11:20, follow the trace of the pwm contact. Looks like there's some ripped pads. Maybe a knocked off smd resistor.
I second that! It sure looks like the pads are ripped off but on the other hand how would it go missing like that?

I have own medium range laptops (like this one) and they never go full spinning unless the thermal paste is completely gone. Nice job Sorin !

Why not use voltage divider using resistor?

what about a small buck converter?

Why diodes instead of a resistor?
Perfect dodgy way for it ! did it today on 1 laptop :)
How about using NTC and putting it over Heatsink.
Would zener diode to the ground be solution, and will consume more energy?
Nice job but:
What if CPU needs more air flow and get overheated then shut down?
I think that the PWM (Pulse Wide Modulation) signal is suffering a distorted filtering due to a shorted capacitor : in this case only "high duty ratio" pulses are allowed to pass across the remaining working capacitors which means full RPM 100% of the time...
Why didnt you use a resistor? I heard you said that you shouldnt but why? and would an inductor work as well for this kind of thing?
I probably missed it, but why no resistor instead of diode?
that kind of diodes can carry 1 amp..
8:41 tool? :))

bios reset?
have you look in BIOS my HP envy 7m has a setting "fan lways on"
Good point
'fan always on' has nothing to do with fan speed
I have seen quite fan in many laptops and desk tops, set to quite fan runs fine.
Do you think maybe Windows has a feature to control the fan speed?
blue line missing from spin.fantastic jump clean and easily bravo sorin for that video.thenks sorin
There was a battery lock trigger at the left ( red dot ) , that's why battery couldn't get out easy.
Have you checked the thermal paste from gpu ? The fan is spinning so fast because the gpu is sending the information of overheating.
hi sorin just a question i was wondering, will the fan turn faster when the processor gets hot? is it dangerous like to damage the processor when he gest hot ? thanks before you answer

Sorin: The original SMD diodes are Schottky diodes. The latest 4 diodes are Silicon diodes.

When CPU work 100%, You got a overheating with that RPM. Not good idea. That is nice laptop, beter to fix original problem
he can reduce the cpu speed easy and simple so it will not reach to maximum speed and overheat

What will happen if the machine starts to get hot the fan cant ramp up to cool it down so it will thermal throttle.. Or worse.

thats not important, when is cold is no reason to be spinning at full
