Mounting the HF-A14 Flx in pull configuration?

post #1 of 7
Thread Starter 
I am new to the forum and don't have extensive knowledge of case fans. After some research and reading reviews I am sold on the build quality and engineering of Noctua fans. I am looking at the HF-A14 flx and want to mount it in a pull configuration. After reading all its specs, however, it appears that the areodynamic features of the Flx suit a push mount and if mounted for pull these special areodynamic benefits would not be realized. Am I missing the boat on this issue? Will a pull mount detract from the potential benefits of the flx fan

Thanks

Are you talking about adding it to a heatsink that already has a push fan? Or are you looking at using this as an exhaust fan in a case?

Does it really matter if it's mounted for push or pull? I imagine it only makes a minuscule difference. Either way it's a solid fan.

Also, if you want you can wait a week or two for the Noctua NF-A14 PWM version.

I think that with case fans, the most important considerations are airflow in CFM and the fan's speed in RPM. When it comes to a heatsink, a more important consideration is the static pressure due to needing to push air through a heatsink (or a radiator). The weaker the pressure, the less effective it will be for a heatsink. For a case fan, the static pressure is almost unimportant unless the fan is mounted as an intake and blowing air right at something. Otherwise, a case fan's most important aspect is how much air it can move.

Thanks for that key information. And that is my goal, to to pull as much air out of the case as possible.
post #7 of 7
Well as exhaust case fan it's more push than anything else since it must push the air through the rear grill, or am I missing something?

Also it's the NF-F12 that is kinda weak in pull, the A14 should be good for that - through for heatsinks the best would be the F12, in push configuration.
