i7 8700K clocked at 5.0GHz with a peak temperature of 81°C using the NZXT X53 (240mm) AIO cooler.
Your i7 8700k is running at an OC of 5.0GHz with temperatures reaching up to 81°C, which is the highest you've ever recorded. Idle temps sit around 34°C, Chrome open brings it to about 41°C, and gaming peaks at roughly 63°C. The new Thermal Grizzly Kryonaut paste seems to help keep things stable.
On what job? Tasks below 100 are acceptable, but 81 in demanding workloads are okay. Temperatures above 1.3V are normal if voltage exceeds that threshold.
You mentioned a voltage around 1.35 to 1.38 volts, but didn't specify the exact value.
These conditions are excellent. If everything holds steady, it looks promising.
You're looking for a balance between performance and cooling efficiency. At 5.0GHz, higher voltages can boost speed but also raise heat. Aiming for around 72°C suggests moderate voltage—possibly around 1.2V–1.3V per core or using advanced cooling solutions like liquid cooling or optimized airflow. Experiment with lower voltages and monitor temperatures closely.
All CPUs vary, so determine the correct voltage for your i7-8700K at 5.0GHz.
