No I didn't, but I still might :- ).
Originally I wasn't impressed at all, in second KitGuru review, when they normalized noise to 40dB, there was only 2C improvement compared to Noctua. It originally simply had 3000 rpm ultra high-pressure industrial fans. Everything works with those. Looks like they now have regular Arctic P series just off-brand. I only watched the Linus review, but he didn't have 3990X to test it with.
When Linus compares it on small-die i9 chip, it really shows it doesn't have better thermal transfer or dissipation at all, it's even defeated D15 tower. So all the benefits on Threadrippers is due to die coverage, something that is issue in 3960/3970X (4 dies in middle, spread into 280W) but not at all for 3990X (8 dies across chips, very comfortable dissipation with U14S, but nothing else on market).
I would love to see 3990X test, at noise normalized testing. My bets it would loose, or tie.
But I would probably order it for fun as well. Don't see why they cheapened and made it out of aluminium though, not even the base-plate is copper.
