The graph below shows the average temperature over a 20 minute stress test using Prime95 with the Blend preset. We found this test to be the best at visually displaying the performance of the coolers as it has the highest range of results. We performed a range of different tests to get a broad range of results. The software we used in these tests was 3DMark Time Spy CPU Test, Prime95 with the Blend preset and AIDA64 CPU+FPU which really puts the CPU cooler through it's paces with a heavy AVX based load. We also used Aida64 to monitor temperatures. You'll be throttling in any stress test with a Hyper 212 EVO on a 9900k. Even if you're running max fan speed. Our Flir One Pro thermal imaging camera shows some noticeable differences in heat soak throughout the cooling tower itself between 50% and 100%, which is to be expected. There is also a slightly lower thermal signature in the adjacent regions at full speed, which indicates the added benefit of improved airflow.

Data comparisons are based on data collected from testing performed on our new Intel i9-10850K system, including re-visiting many previously covered products which were originally covered on the prior testing platform which pivoted around an i7-5930k (4.20ghz @1.20v). The performance of the Hyper 212 EVO is where it really shines, and is the reason why it is regarded as one of the best air coolers for the money. We have used various versions of the 212 for years so the results were not surprising at all. Test System SpecsIt boils down to this. You need to dissipate around 200W of heat if you're running at 4.6 Ghz and your cooler has a TDP of 150W. You'll never get full performance out of a 9900k with your Hyper 212 EVO.

Cooler Master Hyper 212 EVO V2 CPU Air Cooler with LGA1700

All tests were conducted in a temperature controlled room at a constant 21°C. All fan speeds were set to the BIOS default setting of "Normal", which worked perfectly as none of the coolers we tested had excessive noise levels.
