Hi
CPU fan is spinning as shown in 2nd shot almost 3000rpm. Don't know if that's too slow? How do you apply thermal paste? As I bought PC new I don't think paste has been removed. Have removed CPU fan for cleaning. There is no fan control. There is no extra fans in case only CPU, graphics and power supply fan. There is a grille with a mount for a fan on the side. Extra fan here may help a bit as it gets fairly hot here in OZ. Thanks for help.
