OC and Cooling
OC and Cooling
Hey everyone, at 35 and 70 it seems fine for the i7 7700K with Prime95 at 5.0 GHz.
Great motherboard. Those VRMs can withstand some serious stress. You might want to try increasing the speed if you wish, but I must admit Prime95 is no longer a good choice for testing your overclocking. Please test your CPU again with AIDA64 Extreme. I rely on it often and discover it actually leads to more crashes than P95 when an OC is near unstable. This makes it helpful for refining your settings.
Hello, I'm checking if a temperature of 35 and 70 is suitable for an i7 7700K running Prime95 at 5.0 GHz. It's fine as long as it's below 95°C, but I prefer keeping the CPU under 80°C. If your motherboard supports it, you can push it a bit higher. What model is your motherboard and power supply?
We haven't completely stopped using P95 for CPU testing around six years ago.
a) The previous version of P95 involved no AVX instruction sets, which could risk CPU damage if voltage spikes by 0.13 volts.
b) The newer P95 model poses concerns due to these factors.
c) Research shows a CPU can reach P95 stability for up to 24 hours before failing during a multitasking benchmark (RoG Real Bench) within two hours.
Thus, we lack a clear idea about whether the current OC will remain stable in regular multitasking scenarios. Temperatures are acceptable, but long-term effects remain uncertain. We avoid seeing temperatures drop to 80°C under stress tests, which might suggest breaking around 70°C during normal use—though actual performance could vary.

We haven't completely stopped using P95 for CPU testing roughly six years back.
a) Did you use the previous version without AVX instruction sets to avoid harming the CPU when AVX is active and voltage spikes reach 0.13 volts?
b) The newer P95 model can be concerning due to this.
c) We discovered a CPU could maintain P95 stability for up to 24 hours before failing during a multitasking benchmark (such as RoG Real Bench) within less than two hours.
Thus, we lack a clear idea about whether that setting will hold in regular multitasking scenarios. Temperatures are acceptable, but long-term effects remain uncertain for years ahead. I prefer avoiding temperatures near 80°C during intensive tests, which might reach around 85°C in some simulations—meaning I'd rarely exceed 70°C under normal everyday use.
You can review this information, but it isn't a large dataset and doesn't cover temperatures.

JackNaylorPE shared his thoughts on CPU testing practices. He mentioned that he hasn't stopped using P95 for about six years. He questioned whether the older version worked without AVX instruction sets, especially considering voltage spikes of 0.13 volts. He also noted that newer P95 models can be concerning due to these factors. He found that a CPU could reach P95 stability for 24 hours before failing during a multitasking test in under two hours. He expressed uncertainty about the long-term stability in normal multitasking environments, though temperatures were manageable. He warned against immediate damage below 95°C and noted that long-term effects are unclear. He also mentioned not wanting to see temperatures drop to around 70°C during application stress tests, which might be closer to 85°C in some synthetic tests. He believes he won't experience such high temperatures under regular use. He provided links for further reading and shared his own setup details, including software updates and BIOS changes.

Hey everyone, is a temperature of 35 and 70 safe on an i7 7700K at 5.0 GHz?
Yes, it's fine. Staying below 95°C is practical, but keeping CPUs under 80°C is ideal. 70°C during load works well.
If your motherboard supports it, you can push the speed a bit higher. What model do you have and what power supply are you using?
I'm in good shape. My board is an ASUA 270E with Crucial 16GB DDR4-2400 and an EVGA 850 B2. I haven't installed a video card yet, but I plan to get one.
Is this your setup?
Weberdarren97 is asking about temperature limits for a specific setup and is seeking advice on CPU and power considerations.

Do you have the same board?
