Someone in the local LLM community has a CPU cooler for Threadripper and has agreed to sell it to me! Once it arrives, I'll be able to run it at maximum boost clock speed!
The cooler that came with the workstation when I bought it was just a standard AIO liquid cooler for Ryzen series processors, so the cooling was a bit of a problem. I'm using a Threadripper Pro 9965WX CPU.
