This all started a year ago, i was on my stock intel cooler and pc case closed and no extra fans.
My pc started overheating and restarting , so i bought a new heat sink a giant zalman copper one , a couple of 120mm fans.
It was fine for a while then suddenly the heat problem comes back , so i open up the case, the pc doesnt restart only with case open.
The heat sink is clean and the thermal paste is fresh.
Then after another couple of months the same problem comes back , the fan is clean the paste is fresh and i had to keep fan speed at 100% when gaming.
Now my pc is at critical temperatures even on the desktop while doing nothing everything is clean , case is open and fan speed is high.
Bios shows that the cpu is 29 c , while other programs say its 60c on desktop. Oh and its random , some weeks its 40c on desktop and other weeks its 60c on desktop while idle. Nobody i ask can explain how this is even possible.
CPU - Intel q8200
Motherboard - Gigabyte GA-G41MT-D3V
