I have my core i7 over clocked at 4.6GHz and when I run prime95, my temps reach the low 90s. I know this is quite hot. I have tried reapplying the thermal paste and that hasn't seemed to help. Any suggestions?
What are you using as a cooling system?
Sounds to me like you are just not getting enough cooling space and airflow. Low 90's in Celsius is getting into danger zone. Remember that that 90°C is AVERAGE over the chip; some transistors are creating more heat than others.
I am using the Noctua NH-D14 and using RealTemp to monitor the temps. I just installed the ASUS AI Suite that came with my motherboard, and it is saying low 80s for the cpu. Is it possible that RealTemp is just giving incorrect readings?
RealTemp may be reporting the core temp while the AI Suite may be reporting the CPU temp.
So then I should go by AI suite and not realtemp? Even AI suite goes into the mid - high 80s after a while
Sounds like AI Suite is giving you an average from the system board thermistor, where RealTemp is reading off of the CPU itself. I've often seen that the CPU will read far higher than the board, but this is likely because the CPU reader is ON THE TEMPERATURE PRODUCING ELEMENT. And, for sake of safety, always believe the highest temp.
Good guidelines to go by as what eire mentioned. I've experienced the same ordeal with AI Suite and it drove me crazy as well. If it still concerns you, you might want to make sure your cooler is proper seated once more. '~';
I did redo the cooler once more using the "grain of rice" method and not spreading it, I also realized I had my voltage too low, after adjusting, I was at 4.2 GHz and the highest temp was 75 within 3 hours. I just upped it to 4.4GHz and am testing now. So far I am at 74 degrees for the highest but haven't been running as long
edit: after about half an hour, the highest temp is 80 degrees. Not too sure if I wanna try and push it further. What do you guys think?
Ah, running low can be worse than running high! Those i5 and i7 CPUs have voltage control capabilities on-board, and during a weak power bit can actually raise the voltage up MORE than the deficit, which means hot!
Again, a question I never asked!
Have you let the paste even cure before overclocking?
no, but im sure it's cured now
Not sure which i7 you have, but I have an i7-930 overclocked to 4.01GHz and watercooling. It idles around 41C and under load get to high 50's. Might want to include which i7 you have since it would make a difference trying to overclock to 4.6GHz.
oops! forgot that! I have the i7 2600k
