A few years ago I used a Noctua U9S in a different case and sold them together. For the M1 I bought the Atlas, so I can provide you with temps but not a comparison. Because Alpenföhn discontinued the Atlas I think there are only a few around sitting in a NCase. Out of my memory the Atlas is a bit more hefty and the dual tower design should also help. I am guessing maybe a few (max 3°C) difference to the U9S at same settings?!Performance wise I am really happy with the Atlas. I am using the NCase M1 V5 with the glass panel so the Atlas should be one of the best coolers for that. Before changing the GPU I used a deshrouded GTX 1070 with bottom fans pushing hot air out. The Atlas is taking cold air from the rear. Chanced the Atlas fans to the NF-A9 chromax a year ago. Since then the only source of audible noise where the two bottom fans under GPU load. The processor under the Atlas is a R7 2700X with PBO enabled. Reaching 3,8Ghz to 3,9Ghz allcore at high gaming loads. Max Temps are around 75°C, but with a fairly conservative fan speed around 900 rpm I think. At the moment I am not really able to test, because the RTX 3070 is heating the whole case by a massive amount.The GamingPro should be a decent deshroud candidate, but I planned going watercooled with an external radiator. Unfortunately my RTX 3070 does have quiet some coil whine issues, so I hesitate paying a lot of money just to be able to hear loud coil whine without fan noise. Deshrouding with the GTX 1070 worked pretty nice, but under gaming load the computer was far from "silent".Maybe we could find a "baseline" to compare the performance of the Atlas. Something like 1000RPM and 100W CPU Package Power (according to HWInfo)?
