With a Noctua NH-D15 and about 30 minutes spent tweaking the motherboard fan curves I was able to get my 5950x to not thermal throttle without producing any noticeable fan noise.

This seems extremely over-engineered and sounds like it could have been solved by using Noctua or similar quiet fans.

The author specifically mentions (multiple times) that they are using Noctua fans...

Not exactly the optimal Noctua fan, considering it's a high RPM redux.

How did you achieve this? tweaked by hand? i'm in the middle of building a pc and would love to know more.

I just played around with the fan curves. The Noctua fans are pretty damn silent below a certain speed (especially with GPU fan noise usually being louder). So I tried to keep them running faster than necessary at lower speeds and only ramp up a little bit when the temps go up, except at 80-85 or so degrees at which point I ramp up much faster until they're basically at max at 95 degrees. The CPU never really seems to hit those temperatures, as the NH-D15 is an over-sized cooler even for that chip.

Most of the work is in stress testing the CPU to see what you can get away with without thermal throttling. Also helps to do this in the summer if you're in a no-air-conditioning-by-default country.
