AMD Threadripper 2990WX Cooling Performance - Testing Five Heatsinks & Two Water Coolers

And during the graphics/gaming type workloads, the Threadripper 2990WX stayed nice and cool with the 32-cores / 64-threads not being loaded.

Lastly is a look at the Threadripper 2990WX temperature over the five heatsinks and two water coolers tested. This was about two hours of continuous benchmarking on each of the Threadripper cooling products tested. The Enermax Liqtech TR4 240 easily did the best overall with a minimum temperature at idle of 23 Celsius, average of 41 degrees, and peak of 52 degrees. The new Cooler Master Threadripper heatsink did the best overall of the air cooling solutions on the 2990WX with an average of 51 degrees and peak of 67 degrees. The Cooler Master heatsink was followed immediately by the NH-U14S TR4-SP3 from Noctua that was doing a great job if that 140mm cooler will fit within your chassis otherwise the NH-U12S and NH-U9 also did the job well -- and the NH-U9 TR4-SP3 will fit within 4U enclosures. The only cooling solution that was woefully underequipped as expected was the Dynatron A26 2U heatsink that isn't designed for the 2990WX but was tested anyways for seeing the thermal throttling impact where as the other coolers didn't encounter any measurable throttling with the heavy multi-threaded tests.

If you didn't look at them yet, be sure to check out all of our AMD Threadripper 2990WX Linux benchmarks in full. If you are interested in more TR4/SP3 thermal benchmarking there is my recent AMD EPYC Noctua cooler tests.
