I cleaned my Cpu fan in the morning but after 2 hours of playing game, my computer got shutdown( cz of overheat), when i checked the fan again, it was way slower, and when i touch that it became fast again for a sec n then slow again, is this problem with power supply or its the faulty fan? can a fan speed software help me
the fan automatically speeds up and slows down depending on temperature. You can go into bios and turn of the auto fan speed so it runs at full speed all the time. If it still doesnt run at full speed, buy a new fan.
