Core i9 12900K OC at 5100 MHz 1.3 volts
Time for overclocking. Our Core i9 12900K was set to 5100 MHz at 1.35 volts. 1.3 V and higher voltages could cause severe problems for Coffee Lake CPUs because of the TIM used under the heat spreader. Luckily, the 9th to 12th generation uses solder again. Again, wPrime 2.10 (3 times, 1024 M) was used. IDLE temperature measurements are taken on the desktop, with almost no stress to the CPU.
The temps shouldn’t go beyond 90°C, as otherwise, the CPU might degrade and throttling can occur (primarily applicable to the AMD Ryzen range, which generally operates at lower temperatures). Air coolers usually have a tough time with our Core i9 12900K. The Alphacool Eisbaer Aurora 360 HPE performs well. So let’s try to push the voltage beyond the 1.3 V mark.
Core i9 12900K OC at 5100 MHz beyond 1.3 volts
There are four stages for the charts below:
- Default
- 5.1 GHz @ 1.3 V
- 5.1 GHz @ 1.35 V
- 5.1 GHz @ 1.4 V
The Alphacool Eisbaer Aurora 360 HPE managed to keep the CPU temperatures under control until 1.35 V. The result is still really nice, but the noise increases.
