I have an e6400 Core 2 Duo with a scythe infinity cooler and a Gigabyte DS3 mobo. I have applied and reapplied my arctic silver, doing exactly what the manual says and put a straight line down the middle. Then I place my scythe on and turn it. I turn on my comp and my temps usually are 40-45 idle. Under TAT 100% load they are anywhere from 55-65. Prime 95 is usually a little lower. I have tried things including pushing my cooler up because I know how this specific cooler could sag and reduce the cooling capabilities. I HAVE NO CLUE AS TO WHY MY TEMPS ARE SO HIGH! I also throughly clean my cpu and cooler with alcohol before I reapply my arctic silver. I assumed that after going through 1 3/4 tubes of arctic silver I would apply my arctic silver right so I don't think that that could be the reason. Or am I reading my temps wrong? At this very second TAT reads my temp at 47 degrees, core temp reads 46, and speed fan reads it as either 39 or 35 degrees (I never managed to figure out which temp is my cpu and which is my ambient temp. I'd be eternally grateful for any suggestions or information someone could give me.
