I am using an amd athlon II x3 445 rana @3.1ghz unlocked 4th core. with my stock cooler i was getting idle temps of about 40C which i thought was high so i decided to by a new cpu cooler. I bought the one in the title and now im getting higher temps. i used tuniq tx-2 paste where as last time i just used some dynex paste. I tried doing the paste twice with my new sunbeam and im still getting pretty high temps of about 45C idle. Was this cooler a bad choice? or did i possibly mess something up?
