Are my CPU temperatures safe?
Are my CPU temperatures safe?
My computer setup includes a NZXT source 530 with four exhausts and four intakes, an i5-4690k processor, Noctua nhd15, and MSI z97a gaming 5. I'm just starting out with overclocking, so all the tips are useful! I pushed my CPU to 4.5ghz at 1.25v. During stress tests, the temperatures reached:
- 75°C during an Intel burn test
- 83°C using prime95, after which fans sped up and it settled around 80°C
I'm curious if these readings are safe for stress testing, especially since I don't expect to hit those numbers while gaming. I also live in Southern California, which is cooler now, but what should I do if temperatures rise further?

Consider using Prime95 version 26.6 if you haven't yet, as it might yield more accurate temperatures. As ak47jar3d mentioned, I aim to keep it below 80°C. After installing 26.6 (previously 28.7), the peak temperature reached was 62°C. Not sure if that's accurate. The main thread also states: "Optimizing for CPU architecture: Unknown Intel, L2 cache size: 256 KB, l3 cache size 6 MB" compared to another version that mentioned "core i3/i5i7". I ended up settling for a lower frequency of 4.4GHz, since the temperatures are more acceptable and I don’t think I’ll regret the slight loss of speed. 26.6 seems the best choice for newer systems, likely due to issues with other versions causing unrealistic stress. 62°C looks reasonable.
Sergeant_Sneaky suggests using Prime95 version 26.6 for better accuracy, aiming for lower temperatures. Ak47jar3d advised keeping the temperature under 80°C. After trying version 26.6, the maximum reached was 62°C. The documentation mentions specific CPU details, while another version listed a different architecture. Ultimately, the user chose to reduce the clock speed to 4.4ghz, finding the results satisfactory.

Later I chose to lower the frequency to 4.4GHz. The temperatures are more to your preference, and I don’t think I’ll miss that extra 0.1GHz too much.
26.6 seems the best choice for newer systems, possibly due to unrealistic stress in older versions. 62°C looks reasonable, especially with a cooler. You could also check your gaming temperatures if you want more details.
