why my AMD a6 5400k is having a high temp, I'm using Hwmonitor to check it and the Min of my cpu temp is 50c and the max is 90c, 50~65c on Idle, 55~90c in gaming, I turn my CPU fan to full speed and it reduce 2c only, I change my thermal paste, I update Bios and apps, but nothing change just the 2c, what should I do now?
