Time for the overclocking. 1.35 V and higher voltages can cause serious problems for Coffee Lake CPUs because of the TIM used under the heat spreader. Luckily, the 9th generation uses solder again. Our Core i9 9900K was set to 5000 MHz, at 1.35 volts. 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 also throttling can occur (especially applicable to the AMD Ryzen range, which normally operates at lower temperatures). Air coolers usually have a tough time with our Core i9 9900K. The Deepcool AS500 is not an exception. Let’s try to push the voltage beyond the 1.35 V mark.

 There are four stages for the charts below:

  • Default
  • 5.0 GHz @ 1.35 V
  • 5.0 GHz @ 1.4 V
  • 5.0 GHz @ 1.45 V

The Deepcool AS500 managed to keep the CPU temperatures under control until 1.35V, the measurement at 1.4 V was already above 90 degrees. The final result is nice, considering the size of the cooler (as it's a very slim one).
