Testing / comparing : Intel D975XBX2 / Asus P5B DX ***56K WARNING***

heikis : 2x1gig D9DQW work great

GPSeek : 1.375v bios, 3.6ghz -> core temp = 36-37c idle, 63-64c loaded (its currently inside a silent case, 2 noctua case fans + 1 noctua in T120 all controlled by mobo)

note : cpu and t120 are lapped

Thanks for sharing your data
I finally re-installed the tuniq tower. I found the tower is very flat though it is not mirror-finished . The problem is that my Xeon 3060 IHS is quite concave It really needs to be lapped to get better contact with the heatsink. However, I decided to leave it as is to keep the warranty and had to to put more AS5 than I like to.
The result is still about 5C higher than yours no matter idle or full load. Therefore, now I believe lapping IHS is really helpful.
