i've been looking around at some sites for case fans and i'm unsure what to get.
part of my problem is dBA:cfm. whats good and what isnt?
some numbers: (all from the 2cooltek web site)
vantec stealth 92mm at 20dBA : 28cfm ($11.00)
80mm at 21dBA : 27cfm ($11.00)
vantec tornado 92mm at 56.4dBA : 119cfm ($18.00)
80mm at 55.2dBA : 84.1cfm ($18.00)
from the numbers i can see that the tornado is almost 3 times louder, but how loud exactly is 56dBA? (deltas are always called 'screamers' and they are only 48.5 dBA)
28cfm seems really small in comparison to 119...
cooling as of right now (mid sized tower):
bottom front 80mm intake, or maybe its a 92.
80mm exhaust in the back ducted to the coolermaster that came with my 1.4 t-bird
hard drive cooler in the front with the fans turned around to exhaust (my hard drive is actually mounted in the lower rack)
the side of the case is off
what i'm thinking of:
+ 2 80mm fans on the side of the case, intake. one over the cards and the other over a thermalright ax-7
+ a 92mm fan to exhaust on the top of the case
maybe getting rid of the hard drive cooler. if i keep it i will be mounting a hd behind it and turning the fans around
q's:
those fans are just examples, does another company make some with a good compromise between dBA:cfm?
instead of the 80 over the cpu would a duct to a hole in the same place work almost as well?
what about high cfm 80mm fans over the cards, on the heatsink and a 92 exhausting out the top with a low cfm over the cpu?
how hard would it be to install a (rheobus/rheostat.. whats the diff?) on each of the 3 new fans?
with 3 80s blowing in do i really need a fan on the top to exhaust?
a good place to order some of this stuff (fans, grilles, heatsink) from? pref. in canada.
thanks for your time.
