So recently I decided to overclock my old rig which has a Q9450 in it so I decided to buy an aftermarket. I picked up an antec kuhler box and installed it using AS5 thermal paste. However when I booted up the computer and checked the temps (using real temp) it showed cores 1-2 on 58 and 3-4 on 44 degrees Celsius on idle. I tried reseating the heatsink but I still got the exact same temperatures. If I run prime 95 (stock) the temperatures hit 70s and 80s. Also the weird thing is that when I touch the heatsink it isn't even warm until i stress test it, then it blows out warm air. Does anyone have any idea why this could be?
