Does SP fans push less than air than AF even in open space?

theProvider

I'm trying to decide whether to just use SP fans on everything including the front intake and rear exhaust.  Does anyone know or have a video or article that did this test?

Look at the cfm rating of the fans, normally the they blow about the same air with no pressure.

 

for example with the corsair af120 vs sp120, the sp is 62.7 cfm and the af is 63.7 cfm. Corsair doesn't give a proper data sheet, you cant see the pressure vs airflow curve.

At the same rpm, the AF fans move more CFM than SP fans.

Both are pretty bad though, something from noctua or bequiet will move similar amounts of air while being much quieter.

I guess I'm just wondering if those ratings are as advertised... lol

ratings are normally pretty good, esp for the big oems like delta, ebm papst, and others.

 

Really, just get the sp fans and spin them slower if you want it quiet.

noctua also costs more doe

That would be because their fans give the best performance per RPM for whatever use case they're used for. In the case of their new series, of which only the 120x15 and 200mm's are available, they are the best in all categories of real world usage since nobody runs fans completely unobstructed or flush against a wall.

You need very little actual airflow in a pc build to make it run cool and quiet. the difference between an AF120 and SP120 is largely negligible, so I would suggest just getting whatever affordable SP fan you want and call it a day. You don't need more than 1-2 fans in a system anyway, beyond that you're going to be getting minimal temperature improvements in most situations.

 Yeah, it won't have quite as high CFM, but it's close enough.
