Title says everything, what is best? my room gets kinda dusty, but i don¨t know if i should still get SP for less dust or AF for cooling, CPU is Water cooled, rest is  air cooled.

SP is for rads and heatsinks.

 

AF is for cases.

^^^^ this

 

You could get away with using an SP fan on your case but only if it blows directly onto a drive cage. Else AF all the way

I've read somewhere (i think it was in OCN) that putting filters (or any other obstruction really) on AF basically kills the CFM of the fan. like up to a third.

 

But that guy may have been biased to SP fans.

Corsair AF are practically useless, SP ones are better in every case; they only have a bit less airflow but much more pressure and tehy're quieter.

Check on coolingtechnique

Static pressure is useful if your intakes are filtered.

Dust filters or any obstruction do inhibit a lot of performance for both AF and SP fans--it probably halves performance more the a third but it may depend if there are other obstacles in the mix.

AF120's have a fine amount of static pressure for just about anything that isn't a dense heatsink or rad.

Where'd you get that SP120's are quieter? From personal experience, specs, and every review I've seen, AF120's are quieter and perform well for most tasks.

my point (or the way I understood it) is, if you're gonna filter the intake, SP dat slot.

I did--I don't see how that matches what you posted. 

CFM and static pressure measurements don't directly translate to performance. Aerodynamics isn't that simple.

For comparison on performance/noise on a heatsink, look at SPCR's comparison: http://www.silentpcreview.com/article1342-page9.html

 

my point (or the way I understood it) is, if you're gonna filter the intake, SP dat slot.

Static pressure is always needed but every fan has static pressure. How much is optimal depends on the restriction and AF120's have plenty for dust filters.

That was for audio files. Moreover, we're talking about case fans not radiators

The SP have a better design overall

Audio through a microphone don't give the most accurate representation of what the fan sounds like. I have both and AF120's sound quieter. 

The fans were tested on a heatsink and not a radiator. The fin density is very different between the two. Cooling a heatsink with a loose fin array is also better for testing case fans since the performance difference of swapping out case fans are marginal in comparison and harder to compare.

How do SP120's have a better design? The fan blades are so large that the trade of airflow for static pressure usually only benefits for dense heatsinks or rads compared to AF120's.

By "radiator" I meant both. In fact, heatsinks ARE radiators.

Point taken. My source actually is  this http://www.overclock.net/t/1394467/ocn-daves-air-cooling-guide

 

This may have been a very biased guide. Or just outdated.

Technically, most ordinary matter is a radiator but such a definition isn't practical for everyday usage or when discussing computer cooling.

The guide gives good general points but airflow is a bit too complicated to be that clear-cut. Most good fans have a decent amount of static pressure even if they are more airflow-oriented.

Interesting. You make a good point, but you just shattered my whole "put Scythe GTs everywhere there is a fan slot" on my build.

 

I will go back to researching other fan choices now T_T

GT's are still great fans--there aren't many better fans to change to from them.

Yea, I just knew lately that they were actually made to be case fans, not radiator fans. So yea, looks like my "GT all slots" philosophy still holds. hahaha
