I'm running a new 920 system overclocked to 3.2GHz, and the temps are a bit higher than I was expecting. I'm not sure if I'm doing something wrong, or if these temps are actually in the correct range. I'm new to this and unsure what to tweak.
Specs:
Core i7 920
Thermalright Ultra 120 Extreme heatsink w/ single 120mm fan, arctic silver 5
Lian-Li PC-A71A
Gigabyte GA-EX58-UD3R
3x1GB G.Skill DDR3-2000 (PC16000)
EVGA Nvidia GTX260
Windows XP 32-bit
With everything at stock speeds/voltages (turbo enabled, so 2.8Ghz), the cores idle around 30-35C. With prime95 running for half an hour, they eventually would reach 55-65C. I've built loads of PCs, but this is the first one I've overclocked, so I opted to let gigabyte's included easytune program handle it for me. Using that app I bumped the cpu up to 3.2Ghz (turbo disabled), and the ram up to 1920Mhz. I allowed the app to handle voltages automatically, and core voltage ended up at 1.328V.
Upon reboot, idle temperatures are in the 39-44C range. I ran prime95 for about half an hour, and killed it when core 0 reached 80C. The final spread was about 75-80C. I took a screenshot halfway through this process, with coretemp, CPUZ, and prime95 open: here. Temps seemed to steadily rise throughout the test, without ever really reaching a peak.
So, my questions are these: First, do these temperatures seem reasonable for such a minor overclock with a monster heatsink? If not, where should I start? What CPU/Dram/etc voltages should I be using? Any other suggestions/comments/questions welcome.
