Wasn't sure if this should go in the PSU sub-forum, but I figured the right kind of builders would see it here.
Trying to wrap my head around picking a good replacement, I know that the Noiseblocker PC-P is recommended.
The SP120 (Quiet) moves more air but has lower pressure.
The SP120 (Performance) seems overspec for CFM, but almost has enough pressure to match the stock fan. It's possible that it would spin so slowly that the sound might be lower, don't know.
After looking at all the specs here, the Noiseblocker actually seems underspec for the job. It moves almost the same amount of air, and has 2/3rds the pressure.
Based on the research I've done, matching CFM and Static Air Pressure are the two most important things for swapping this PSU fan.
AD0812HB-D70:
Airflow 29.9 CFM
Static Pressure 3.2766 mm/H2O
Sound Level 33.4 dB/A
Speed 3200 RPM
Power Draw 12V 0.18A 2.16W
SP120 Quiet Edition:
Airflow 37.85 CFM
Static Pressure 1.29 mm/H2O
Sound Level 23 dB/A
Speed 1450
Power Draw 12V 0.08A 0.96W
SP120 High Performance Edition:
Airflow 62.74 CFM
Static Pressure 3.1 mm/H2O
Sound Level 35 dB/A
Speed 2350
Power Draw 12V 0.18 2.16W
Noiseblocker NB-BlackSilentPro PC-P:
Airflow 30.6 CFM (max)
Static Pressure 1.89 mm/H2O
Sound Level 25.8 dB/A
Speed 2500 RPM (max)
Power Draw 12V 0.13A 1.56W
Anyone have any insight here? Basically just trying to find a high performance, quiet fan that meets the thermal requirements for the PSU.
E: I have no idea how to format those numbers better.
