Replaced a water cooler with a traditional heatsink as a precautionary measure. I've been using this AMD Threadripper 3990X 64-core CPU for two years, and I really liked it! I'll probably use it for at least two more years.

what kind of air cooler can handle this for instance? Will a regular consumer-grade chunk like NH-D15 do?

I bought this:

Noctua NH-U14S TR4-SP3, Premium-Grade CPU Cooler for AMD sTRX4/TR4/SP3 (140mm, Brown)

Continuing the legacy of Noctua’s classic NH-U-series, which has received more than a thousand awards and recommendations from international hardware websites and magazines, the NH-U14S has become a...

i wonder why they don't have 15 models for threadripper socket. Is it that the surface is so large that it cools better?

They have relative performance numbers at noctua.at/en/products/cp based on their Noctua Standardised Performance Rating (NSPR). NH-D15 is one of the oldest designs in their current product line and desperately needs an update. It's still their highest performance cooler though.

NH-U12A has NSPR 169 which is really close to NH-D15 183 because it has their newer heatsink and fan designs. They only made a single Threadripper cooler because it's a tiny market. You can see they don't list it as having maximum turbo perf for 64 core: ncc.noctua.at/cpus/model/AMD

Their timeline is Q4 2022 for the next generation 140mm fans and Q1 2023 for the next generation NH-D15 using those. Zen 3 Threadripper got delayed for years and hasn't launched as a retail product. When AMD and Noctua finally launch those, there could be a Threadripper NH-D15.

For the time being, these are the only air coolers able to get the best performance from 64 core Threadripper or overclocked 32 core Threadripper: icegiantcooling.com Beats best closed loop water coolers for Threadripper but it's ridiculously large / heavy and isn't cheap.

i use u12a. Didn't know d15 was an old model but just the balance of the size and the performance seemed to hit the diminishing return point at u12a.(and reviews seem to show that 169 and 183 are more like 179 and 183; no difference)

The NH-U12A has 7 heatpipes compared to the much larger NH-D15 having 6. I think it would have at least 9 heatpipes with the new design. Those new 120mm fans are also so much better than the old ones. The new 140mm fans are going to be amazing. Has been so delayed though.
