I have The 1700 with the boxed Wraith RGB Spire cooler and it is silent. The threadripper has a Wraithripper tower HSF unit that is fairly silent and mounts with 4 screws through the top of the HSF. In tests at Phoronix, it cools quite well even with 64 threads banging away. On my older Phenom II X6, the venerable CM Hyper 212+, I changed its sleeve based fan for a rubberized "QUIET" dual row ball bearing fan which has inaudible noise while still having more airflow and cooler than the stock fan. Even the attach points have rubber grommet sleeves to further reduce noise. I have to look to see if it is running. Its that quiet. You could look at the cooler review at Phoronix for some ideas.

2990WX cooler review.
