Just looking for some advice here. Basically my i7 920 @ 4GHz bundle arrived yesterday and I have built it into my old Antec 1200. After installing the drivers I ran prime95 which reached temps of 79-83 C (4GHz) after 7 mins or so before BSOD.

I have gone into bios, turned off HT and reduced the Vcore to default (some 4 or 5 notches lower than what it was at) and tried prime95 again. This time it completed 1hr of the prime95 blend test before I stopped it. Temps reached between 8 and 10 C less than previously. I have read that HT requires more Vcore but I'm worried about temps that way. Do you have any advice? Is HT really worth leaving on ?

Stooeh

P.S I feel I should mention that I'm using the Noctua NT-H1 thermal paste as no AS5 came with the bundle. The invoice seemed to indicate that AS5 should have been present but quick look online seems to show that the noctua stuff is quite comparable ?
