Big Boy Heatsinks: The 64-core AMD Threadripper 3990X Cooler Test
Reported today on TechSpot For the full article visit: https://www.techspot.com/review/1995-amd-threadripper-air-cooling/ Big Boy Heatsinks: The 64-core AMD Threadripper 3990X Cooler Test After reviewing the Threadripper 3990X, it was made clear the 64-core/128-thread beast from AMD lays waste to every HEDT part we have ever tested. It's an insane productivity CPU, that we pushed to extremes to torture a few motherboards just this week. Then we thought, why not try out some big bulky coolers as well? To date all our TR 3990X testing has been conducted using a large 360mm custom loop setup with Corsair's HydroX bits. This allowed us to keep the 64-core part under 70C during an hour-long Blender stress test, though as expected temperatures did climb rapidly when overclocking, peaking at over 90 degrees. This had us wondering just how practical air-cooling the 3990X would be, especially for those wanting to overclock. As luck would have it, on hand we had four purpose-built Threadripper air-coolers from the likes of Noctua, Arctic, DeepCool and Cooler Master. For testing we're using the DeepCool New Ark 90SE case from our VRM test setup, tested under a 21C ambient temperature. We used the Gigabyte TRX40 Aorus Xtreme motherboard and the Gooseberry Blender workload to stress the CPU. All fan speeds were controlled via the motherboard using the CPU PWM fan header and with the F4a BIOS for the Aorus Xtreme, we've left the 'normal' fan profile active, so the fan curve has not been altered in any way. With those notes out of the way, let's jump into the results and then I'll talk about the cons and pros of each option. Benchmarks First things first, here is how each cooling solution works with the Threadripper 3990X at stock. As expected the Corsair HydroX delivers the best result thanks to that large 360mm radiator, but we've go
