Hallo, I have a core i7 920 which is getting very hot, in idle it''s about 46 C on each core, and running prime95 on 8 threads it reaches 70 C in seconds, and keeps on rising till it hits about 85 C, which I think is extremely hot for a CPU.
If I set my ram on stock speeds (1600mhz on 1.65V) then the CPU gets a 5-10 C hotter.
Ambient temperatures are around 25 C.
In prime95 i sometimes get an error on a core after just a minute or so, and it stops the test on that core. But I have had it running over night without errors.
Ram is tested with memtest86+ over night without errors.
Is something wrong with the CPU, or are these temperatures normal for a core i7?
I have tried refitting the CPU cooler 10 times or so, with 3 different thermal paste, Noctua, AS5 and Zalman.
I checked the CPU socket, to make sure the CPU was higher than the socket brackets.
Any help, advice or good suggestions would be much appreciated =S
My specs are:
Antec p182 with 4 Noctua NF-P12 120mm fans running on lownoise ~1200rpm.
Asus Ramgape II GENE motherboard with everything set on auto in bios.
Intel Core i7 920 D0 stepping running stock speeds with turbo enabled, aircooled with Noctua NH-U12P push-pull on lownoise ~1200rpm.
6gb OCZ Reaper 1600MHz running 1066 MHZ 1.5V
Gainward GeForce GTX 275 with 2 fans
