Assistance for OC I7-9700K on Aorus Z390 Pro
My setup includes an i7-9700k, Aorus Z390 Pro, Corsair 16GB 3200mhz, Noctua D15, and NZXT H700. I used the Gigabyte guide for 5GHz and achieved stable performance with AVX offset -3 at around 1.31v. On Prime95 with AVX, it ran smoothly at 95c without issues; without AVX, it peaked at 87c without problems. In games, the CPU stayed near 75c. Are these temperatures safe for continuous use, or should I adjust the offset?
Those temps are higher than average. 75c when gaming and that's in winter? You're looking at 80+ in summer.
Technically these temps are usable, but I think you should drop a notch by 100MHz and some voltage, running warm is not worth it for something like extra 100MHz.
Too high for me. You aim to maintain temperatures under 80°C for full load OC readings.
Gaming at 75°C is still too high. With the Noctua, you should really be achieving much lower temps. I’d suggest targeting around 55-65°C for gaming loads. 70-80°C for stress loads.
I agree with Gaidax. Reduce it slightly. Keep your prime95 temps under 80°C and work from there. Perhaps even lower the frequency by 200MHz for all core overclocking to stay below 80°C.
I’ll recheck later in the games and see if I was mistaken. If you skip the 75c in-game, are the stress test temperatures acceptable?
Should I run the tests on prime95 with AVX or without?
Do I need to reduce the voltage as well?
I really hoped to reach the 5 point.
When the voltage drops, performance improves since it reduces temperatures and hinders electron movement.

- Are you asking about 80c on prime95 with AVX enabled or not?
- Should I also reduce the voltage?

🙁
For me, 87c without AVX seems too high.
That's exactly what I meant. As Supahos mentioned, lowering voltage will lower temperatures. The goal is finding a balance among temperatures, voltage, speed, to get consistent results.
Yes, some chips can hit 5GHz while others can't. It really depends on the silicon. Sadly, it's a lottery each time.
I'll look into it this evening and let you know, thanks. Also, could the thermal paste be applied incorrectly or are the screws not seated properly?
so here are the findings—
with prime 95 at stock speed, the minimum temperature stays at 35°C (my room is roughly 25°C), while the maximum reaches 70°C.
with prime 95 no avx at 4.9GHz @ 1.31v, the peak temperature is 82°C across three cores, with the rest around 79–80°C.
by the way, winter here is about 19–29°C, so it isn’t that cold.

at 4.9ghz with 1.3v, the peak temp hits 82c on 3 cores, and the rest falls between 79c and 80c.
by the way, winter here is about 19c to 29c, so it’s not that cold.
note though, ambient conditions affect your PC/cpu temps too. but you still need to consider that.
at 82c with [email protected], you’re right at the limit for me. others might say differently. i wouldn’t go beyond this point and stick with what you have. testing with prime under those settings for a few hours will confirm stability. don’t just test for 20 minutes—my optimized builds run overnight for 8 hours, plus 20 minutes for basic checks.
