Fan blow direction is 100% critical to the CPU temperature.
Some people have mentioned getting 70C or 80C for CPU temperatures. They think to have fixed the problem by changing the fan profile setting to something else because it was set at default. However that is not the case, it would only change the temperature by a few degrees. Normal operating temperature should only be around 50C at most. Fan direction can cause a 20C difference in temperature, i know this from from experience. Retested before posting this. Got 70C when water cooler AIO fans were blowing down into top mounted radiator. Switched the top mounted radiator fans to blow up instead and the temperature, while gaming, was 50C. Closing out topics early can contribute to misinformation, discussion and awareness will help fix this issue. Fans on front side of the case blow towards the back of the case while fans on the back continue to blow out the back from there, while top mounted radiator blows upwards and out. Check fan direction by what side the plastic spokes like thing that holds the motor is on, the air is blowing out towards that.
