unknown . . . please let us know if you test it

Noctua NF-A12x25 PWM did work for the R10 without the diagnostic startup error, but this is subject to change with every BIOS update

@DanM77 

nf-p12 redux-1300 has 1300 rpm max and its 3 pin NON PWM so its not going to pass EPSA Diagnostics. 

ePSA Error 2000-0511
fan failed to respond correctly.  
Dell fans  Are 4 pin PWM  7M0F5 are 4000 RPM.  Fans without at LEAST 1700 RPM will fail POST startup.

They can be found for a reasonable price in USA.

Some Dell fans use non standard wiring and 5 pin connector.

These 1500 rpm 3-pin fans work in a Dell with no diagnostic startup error

I can second that for an R10. Gave me zero issues and they are great fans.

The noctua site clearly states 1300 Rpm max.

Startup error perhaps but EPSA test will fail.

Others also noted needing 4000 rpm dell fans to pass epsa self test.

Which is why i changed to dell fans on my R10.

The Noctua link I provided was to correct your posted misinformation that the fan referenced by OP was "NON PWM".

The fans in the photo are Aerocool 3-pin 1500 rpm fans that were presented to correct your posted misinformation that the fans need to be 4-pin, and that 1700 rpm is the minimum required for a successful POST.

fans need to be 4-pin, and that 1700 rpm is the minimum required for a successful EPSA DIAG test not post startup error. Working fans are 4 pin PWM 2000 Rpm.

This simple fan makes a world of difference if one chooses to keep the stocks fans in these R10-12 machines. It actually pulls the air out with less turbulence and restriction. It is serving me well and it’s actually very quite too. I play with a HPg2 and sometimes with the AW510H so I’m not worried about the stock fans at 49% while gaming. Without this simple fan my cpu/10900KF would run 5-8 degrees higher. These cases lack exhaust ports for flow to exit the case kinda like a automobile.

Lol ! Yeah that’s definitely directing air for sure. But the double top fan is quit an overkill. I’m still searching for a spot for another exhaust somewhere in the back. If There was a way to detach the psu that would help the case out a lot with air flow.
