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.

@AlexZoghb
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.
