I currently have my Duron 600 @ 810 at 1.65v. My idle temp in my Enlight 7237 is around 45c with load at 50c. That is with an Alpha PAL6035 and standard grease. I have an 80mm sucking in at the bottom, one blowing out at the back, and a 92mm blowhole placed on the panel blowing between the CPU and video card. All the fans are Panaflos. I'm selling my 6035 to my brother and am choosing between the above two mentioned as my next heatsink. I'd have to mod the PEP66 to get the fan on top in my KT7. Which heatsink should I get, and which fan should I get? I will also be picking up some Arctic Silver II grease. I appreciate all feedback. Thanks.
