Need help on cpu temps
Need help on cpu temps
Hello everyone, I increased my i7 8700k from 3.70 to 4.99 ghz using 1.424 V. I’ve been experiencing temperatures between 40 to 50 degrees while browsing and watching videos. During gaming, it ranges from 60 to 72 degrees, sometimes spiking up to 80, though it drops quickly. My setup includes two front fans—one on top and a thermaltake water cooler with a flow rate of 3.0. The AIO pump spins at 1448 RPM, the CPU fan at 1778 RPM, and others at 1072 RPM. Is everything functioning properly? Should I be worried? I’m still getting a bit overwhelmed by this level of detail.
I took some photos while playing:

I observed that all cores usually stabilize around 70, sometimes reaching 80, with one spiking to 91 very briefly.
Here are some screenshots of videos I watched:

Slightly warm today. I usually try to keep things under 85, just as a guideline. In theory 90 would be acceptable, but if you pushed the system or played in extreme heat like 40°C, you could go higher. That’s quite a bit above the 105°C limit, so for better durability I’d reduce the clocks or voltage slightly.
Can you adjust the voltage? Also, what are your LLC settings? The Load Line Calibration helps counteract voltage drop when the CPU is under stress. You can apply a bit more voltage at idle so it matches your full-load value.
I’d open the BIOS and start with low LLC levels, then monitor core voltages to ensure they stay above your minimum required voltage during load. For example, my desired voltage is 1.2V, but at idle it’s 1.216V.
From your screenshots, I see your Voltage at max reaches 1.498V, which is quite high. If you plan to use it for gaming, I’d definitely lower it.
Regarding cooling, just run the pump at full capacity all the time—they’re usually quiet.
Thank you for your assistance. I just restored it to the original settings after the CPU overheated by 128 degrees unexpectedly, which made me quite nervous. I set it back to 3.70 GHz, and although I still have much to learn about overclocking, it did help clarify what was going wrong. Thanks again!
