The replacement fan for PH-F140SP is not a PH-F140MP fan.
While they look like PH-F140MP they are not the same .. nor do they have same specifications. Best I can tell they are no-name / no-model number fans that have PH-F140SP outer housing and motor with a PH-F140MP impeller.
I have not been able to get any of these MP impeller case fans, but Phanteks told me
F140MP_BK (3Pin for case installation)1200RPM +/- 250 rpm.
Which is rpm specificaton of PH-F140HP_ii and PH-F140MP at 1200rpm
CFM will be the same as MP
I think that means at PH-F140MP at 1200rpm performs the same as these new case fans .. which is about 66cfm
PH-F140MP are PWM controlled 500-1600rpm; 68.1cfm; 17-25.3dB(A); 1.62mm H2O
"No Name/No Model #" are variable voltage 1200rpm; xx.xcfm; 24.2dB(A); 1.31mm H2O
CoolingTechnique tested the PH-F140HP_II .. the same fan in round housing versus square housing on PH-F140MP
CoolingTechnique testing data is at 1222rpm there is 68.1cfm, and 1.71mm H2O
CoolingTechnique testing data is at 1416rpm there is 79.9cfm and 2.286mm H2O (1416rpm is below 1600rpm spec because load resistance lowers fan speed and all specs are +/-250rpm)
PH-F140MP specification data is at 1600rpm there is 68.1cfm and 1.61mmH2O .
Phanteks shows PH-F140MP and PH-F140HP_II having same performance, but CT test data is radically different from Phanteks data.
I tried PH-F140MP on CLC radiator and the worked quite well. I have not compared them on my Siltent Loop 280mm cooler but suspect they would work well.
I'm trying to get a couple of these newer 'no-name/no-model #' fans to test.
