I followed the PDF from nostr:npub1lrjgpa9m2dl6esdah5pq7m005ymwh4glq4aet76q2zlz2f83esfsa2zvrj and installed the Noctua fans.

They did something with that guide man. And Noctua is great
i tried the 120mm fans on another unit and they are fine - but not as quiet as the 140mm with the adapters. .... running at 666 watts 🤘(6.9TH/s) is pretty damn quiet and plenty of heat for my office. .... oh, and i'm solo mining. thus, i call them "lottery heaters" 😆
