Sp or af

If I were to swap out fans on a heatsink, should I go for airflow or static pressure?? Also howwould I differentiate an airflow fan from a static pressure one??

PS I love this forum, it's soooo alive. Im glad I signed up here

static pressure as you need to push air through the fins of the heat sink,personally I'd use corsair Sp 120 or for a budget wise nearly same performance (though material is less sturdy) I'd go for a coolermaster sickelflow .

Most leading manufactures sites show the static pressure,tho as linustechtips showed corsair are most accurate in the model specifications.

It kind of depends on the heatsink in question.

If you are using it on a case with filter higher static pressure can help, but if it is just a honeycomb style vent, you do not need a powerful fan, you just want to move more air.

Depends on the heatsink...

I have had excellent success with my Hyper 212 with a pair of 110CFM fans on it. For a more "Dense" type of heatsink I'd definitely recommend static pressure. The less room for that air to flow; the harder it is to push through. The static pressure being higher helps eliminate that issue.

cooler is gonna be hyper 212 evo, so how can i tell if a fan is best for cfm or SP?? most fans on most sites like newegg have no mention of static pressure

You'll have to search for the manufacturers page if it doesn't have the ratings on newegg. However, the fin width on the 212 is quite good, so I don't see it making a huge difference. Honestly, when I crank my pair of FM 121's they sound like a jet engine and make it impossible for me to hit 65C no matter what I do at 4.4Ghz ~1.25v load temp.

I'm gonna do corsair sp's on it, since I'm filling my case with them and af's
