CPU fan shows 0 RPM whereas GPU fan is fully functional, CPU fan works rarely.

My Acer Predator G3-572 for some reason now has a problem with the CPU fan not running/idling at 0 RPM even when I set it to max. About a month ago I opened up my laptop and replaced the thermal paste with Arctic MX-4 and cleaned out the fans (after unplugging them, and then re-plugging them once clean), I did that because I was experiencing constant 96 degrees while gaming. Everything has worked smoothly up until now, could that be a problem? I opened up predator sense today and saw that the CPU fan didnt seem to run, even after restarting the laptop/setting fans to max. On another note, sometimes the CPU fan can go up to a maximum of 3500 RPM from time to time, but it would eventually drop back down to 0, and it would never hit 5700 RPM+ like the GPU when at max. Any fix? (See first screenshot)


Also, I have just encountered another problem. when i set my fans to auto or custom, they completely switch off sometimes as shown in the second screenshot.

    This should be a problem with the unit and the CPU fan should run. So would suggest you to send the unit to Acer repair center to check on it.
    Check the below link to send the unit for repair

    AlexZoghb probably even if you has a service center near you they would not cover you by warranty because i suspect somehow when you disassembled it you damaged the cpu fan and user self damage will not be covered by warranty if you need a replacement fan and if you can see that the fan its not physically running drop a pm to @Kev0806 he would sell you the part you need he is an authorized parts partner
