Vrm temps when overclocking
Vrm temps when overclocking
I just assembled a new PC.
V21 thermaltake matx
8600k @4.6 ghz @1.26v
120m liquid freezer aio push pull fans
200m bifenix case fan in front intake
Z370m mortar horizontal in the case
970 evo 500gb
600watt evga 80+bronze
1070 ti mini
It took me some time to understand this build because my board had very limited power limits. I adjusted both to 150 and the throttling stopped. I also set the fan speed in bios for the liquid freezer—70° at 100% push pull fans. It wasn’t too loud. Real temp reached 72 °C with Prime95 AVX on. The CPU was drawing 147 watts, according to hwmonitor. CPU temps were fine, but hwmonitor showed four sensors: one up to 98°, while the actual temperature never exceeded 72°. So I stopped using Prime95 and installed a 120mm high-speed fan blowing straight down at my motherboard. Connected it to a fan controller and restarted Prime95. Once it started drawing over 100 watts, the temperature began to rise. When the sensor reached 75°, I increased the fan speed. The fan is very loud but fast; I managed to set it to a manageable noise level while keeping the temperature at 84°C under 145W draw. That said, while gaming at 4K resolution, I’ve never seen that sensor go above 42°—probably what Prime95 is built for. My question is, do people really pay attention to their VRM temperatures when they OC? I’ve built a lot of rigs and never focused on any VRM temps before. If anyone has tips on handling these temps, I’d appreciate it. If you have suggestions to raise the build without increasing noise, that would be ideal.
There are some cases that provide adequate airflow to keep the VRMs cool, but this can become a problem during extreme overclocking. It shouldn't be a concern for most users. Try Prime95 v26.6; newer versions include AVX, which games don't utilize. Alternatively, you can run CPU-Z's stress test to monitor gaming temperatures.
