I’m running at 4.7ghz @1.34v with all cores at full speed for the first hour, then they gradually drop to lower core usage. After about eight hours I noticed the CPU dropped to around 40%. The temperatures peaked at 58°C under load and ended with a 17°C thermal margin. I think this is throttling. Should I lower the clock speed to 4.5/4.6 or increase the voltage? It hasn’t stopped freezing.

Don't require Prime95 beyond 10 minutes using aircooling or 30 minutes with liquid cooling. With small FFT, the main advantage is reaching the highest CPU temperature possible under full load. Stability checks work better with Asus RealBench. If your CPU slows down after p95 testing, it suggests cooling isn't sufficient or the case lacks proper airflow. A TM of 17 at the end would be acceptable, especially if it's a peak value; otherwise, throttling likely occurred due to heat.

With small FFTs, the main advantage is reaching the highest CPU temperature possible under full load. Stability checks work better with Asus RealBench. If your CPU slows down after p95 testing, it suggests either insufficient cooling or poor airflow in the case. A TM of 17 at the end would be acceptable, especially if it's a peak value; otherwise, throttling likely occurred due to heat.

It was indeed the last figure at 40%. Since there’s no case, there’s ample airflow, so I slowed it down to 4.6ghz and will check upon returning.
