Dell Laptop Processor Fan Not Working

If you have run full system diagnostics from f12 and the same error is displayed then you are probably looking at a bad fan.

Dell laptop processor fan not working.

Desktop pcs have more than one fan processor cpu dedicated or discreet video card gpu power supply psu and one or more chassis case fans. If you ve connected it elsewhere the fan may run when the computer is turned on but it won t be sufficiently cooling the cpu which is its main purpose. Inspiron 1520 laptop cpu fan not working if the fan does come on under diagnostics f12 at powerup but not under windows then it could be a software issue. Check your cpu fan s location.

It should be connected to the cpu header on the motherboard. Please perform a systems diagnostics by pressing f12 at startup or by running dell support assist. The fan will run at optimized performance automatically when there is a change in temperature when it reaches a set temperature. Lint and dust accumulation prevents air from flowing around the cooling fins and causes the fan to work harder.

Processor fan not working. I hope this will work. I have a problem with my latitude e7450 cpu fan it seems to be working fine up until one day i spilled some coffee on the keyboard then i had to disassemble it then i cleaned the keyboard and have reassembled it. If you do that you will disable fan controll.

Dell spare parts at 800 357 3355 have your service tag when if you call. Replacing the fan is the first thing and the least expensive to try. From that point the cpu fan no longer works when i am using the ope. If the fan doesn t come on under diagnostics or windows both and the fan is known good spins freely by hand then it s a mainboard problem.

Your dell pc may contain several fans to keep the internal components cool. The same for this if you mess it up your problem not mine. So your fan is always running at 100. If the fan is not working then i have to assume the system is shutting down as the cpu will overheat.

If your dell is not in the list and it isn t working like in my case you can do one last thing. I don t recommended this because you can easily destroy your pc. Hi tiller112 thanks for posting. What i did and works for my is removing the fan control by disconnecting the fan wire and solder it on the adapther i found that was 6v.
