The Dell OEM industrial grade server fans have a top speed of about 4,000 rpm. So if your Noctua NF-F12 are at their 100% of 1,500 rpm, AWCC will show them as 37% (1500 / 4000 )
I see, but i’ve tried this and theres no audible difference or thermal difference. I did notice in HWiNFO some crazy rpms, like 5000 on the chassis fans so im wondering if theres some software conflict happening? Definitely not going to run at that speed.
I only used a Y splitter for the 2 fans on the radiator, but it wont be too big of a deal. It’s getting equal thermals without them being on 100% all the time which i can appreciate. Thanks for the help
Thanks a lot for the clarification. I do have 1 question though. Do you think it be bad for the fans if I set them to a percentage higher than 37? Or is the controller just telling it to run at its max?
Noctua is a top quality fan designed to run at max rpm, as needed. With air flow being so stifled in the Aurora chassis, I would definitely keep the fans running at 100% rpm. Fortunately, Noctua fans are quiet. You actually could have gotten the Noctua NF-A12x25 FLX 3-pin fans which would run and a constant 2000 rpm . . . quietly.
@ProfessorW00d Question, professor.. Would the FLX 3pin fans run at full capacity constantly, (the 2k rpm's you cited) without the 4 pin connection to the mobo?

AWCC % are hard coded to the original fans. You will need to increase to 75% or higher for the Noctua fans.

Fan controller cannot be read by third party apps, only by the AWCC application.
It might not make a difference as the flow in the R10 case is not the best. You can try 100% and see what happens.
Also make sure you did not use the LNA adaptors that came with the Noctua's.
