That's why you want to get into a DIY parts PC you assemble yourself. Welcome to the world of owning a manufactured PC such as Acer, Dell, HP, etc.

This is your cheapest temporary fix to get you going for now. You may however have a problem with nothing plugged to the CPU fan header so plug a regular case fan here even if you have to buy one for $5.

You are not alone in the world of Acer owners who have ripped their hair out over this problem.įor a quick fix I would just plug the CPU fan into a case fan header if it works, or direct to the power supply molex connector with a fan adapter that you would have to purchase. Other fan control programs seem to not work.

The only solution as you have found is to use Argus Monitor which somehow bypasses the ACER lock on fan seeds. It only turns on the CPU fan at high temps in order to reduce noise. They locked the smart control of the cpu fan with no way of controlling it via the BIOS and claim that it is normal operation. The computer is working as Acer intended. I would plug it direct to the power supply so it runs 100% since the case fans might be programmed to not work 100% of the time.Īnyways, I'm here to reassure you that you are not crazy. But you need a fan plugged into the CPU fan header so the motherboard detects it and doesn't freak out. You could plug the CPU fan into the powersupply or into a chasis fan header on the motherboard to have it spin all the time. Dust is not causing your fan to all of sudden only spin at 100'C.Īfter the first 15 answers people start giving you better advice. If the fan spins at 100'C then it obviously works. Problem.CPU heats to a threshold of 100'C or so before CPU fan starts.Īnswer.well the first 15 answers about the fan, heatsink, thermal paste being defective is a load of horse dung.
