Hey there, I own an 8700k with a 5.1 ghz @ 1.34v cooling setup, including Rockit cools copper IHS and liquid metal. The Asus X Hero Z 370 BIOS is the latest. The cooling system is still quite old but it performs decently for its age. The thermal paste is black, and it has a solid black color.

I know it's outdated, but it still works well. The water cooler pump stopped working, so I did some overclocking to improve performance. My RAM is 16GB with two 8GB TRIDENT Z RGB 3000 MHz chips at 1.35V. I installed them manually at 4000 MHz CL-17-19-19-39 and adjusted the second and third timings slightly. Both DRAM and VCCIO/VCCSSA are stable at 1.21V.

My stress tests included CineBench R15 with 10 loops, reaching a peak temperature of 72°C with a score of 1689. For Prime 95, I got 26.6 with small FFTs over 3 hours, maxing out at 82°C. The Asus Real Bench Stress Test for 16GB RAM showed a similar result: 3 hours with a max peak of 82°C.

I also monitored the hardware using a 64-bit HW Monitor and saw no errors. All temperatures were normal in my 23°C room during summer.

I believe you were talking about the Thermalright True 120 CPU cooler. If that's correct, it's a great choice for its time. Voltages could be high, but temperatures match the clock speeds and voltages.

Yeah, I've had it since my Intel E6600 a long time ago, hehe, she's quite old, I know.
