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 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:

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:

Beats best closed loop water coolers for Threadripper but it's ridiculously large / heavy and isn't cheap.
