902+True fans

[ETNiES]

Been thinking about upgrading my 902 case fans wondering is it even worth it?

If I was to get 3 of these what kind of temp difference would I be looking at? and noise difference?

Also my True Spirit, Would it be worth adding another fan to it? or replacing the current fan?


I don't really no much about fans at all so opinions welcome :>

http://www.overclockers.co.uk/showproduct.php?prodid=FG-015-SY&groupid=701&catid=57&subcat=4 would be a better choice as far as specs go (a nwes site did a test a while back) I'd buy 3, try 2 in the case and 1 on the Cpu cooler, if it makes that much of a difference buy another

Fan specs are primarily BS and only meaningfull value in there is RPM which affects to both airflow and noise.
TriCools themselves are acoustically mediocre at best with speed switch being only saving thing.

Noctua S12 might be very quiet fan but that's because blade geometry is nearly pressure impotent and back pressure brings airflow to crashing halt.
Scythe Gentle Typhoon has very smooth bearing, low noise and very high pressure capable blade geometry but because blade area is small (that big motor) in low impedance situation its airflow/rpm ratio probably is rather mediocre so as case fan achieving similar airflow to good normal fans could cause noise to be at higher frequencies.

If you're keeping Tricools at medium then 1200rpm SlipStream M should roughly match noise level but with clearly higher airflow and 800rpm SlipStream L would achieve slightly more airflow for less noise than TriCool at low. Their weakness is that as sleeve bearing fans they don't like running in horizontal position. (also wouldn't put them to densely spaced high impedance heatsinks)
