High static pressure vs high air flow fan as an exhaust fan with restrictive heatsink in front Anonymous 2016-07-15 10:38:12 Post No. 55585747 [Report]

I'd like to replace my only case fan which is a Noctua NF-P12. My mainboard can't properly control it since it has no PWM which means it's too loud.

My case is fairly small (Cooltek C3) so the fan is wedged directly in between the case grille and the CPU-heatsink (it really touches both).

My question is, do I need a high static pressure fan (because there's restrictive stuff in front of the fan - the CPU-heatsink), a high air flow fan (becase there's no restrictive stuff behind the fan - except for the case grille) or something in between (see second pic).

Which fan should I order? They all cost pretty much the same.

You should use static pressure fans in most cases (intakes and heatsinks and radiators). Use airflow fans only for exhaust, but static pressure fans work too.

To add on, exhaust as in case exhaust only. Not heatsink exhaust.

I'd love to but there are no mounting options for intake fans, only holes in the bottom for air to be sucked in.

>>55585777

So, NF-F12 it is?

I get it: i bought a 40 dollar cooler myself to get a silent pc but why the fuck would you need extra premium exhaust fans with a cpu cooler like that?

Can't go wrong with the NF-F12.

get a fan that is in the middle, that is both high pressure and high air flow hybrid

Thanks bruv.

Just talked to Noctua and they recommend the high air flow version in that case because of airflow already present because of CPU-fans

i you have an AMD you can buy a fanless heatsink since AMD is the coolest cpu in the market (especially FX series) at the moment. you may need to sacrifice a bit of mhz though.
