80mm cheapo psu fan cfms?

[MiracleMan]

Anyone could estimate how much cfm have that cheapo psu 80mm fans? could 4 80mm fans like that overperform one 120mm (using at my huge radiator)? :eh?:

[RangerJoe]

prolly not, the fans in psu's are made to be quiet, not to cool really well, so go out and get one of those delta 120mm's, they put out 190 cfm, that would cool your radiator just wonderfully. but if you want a quieter one, go for panaflo, their H1A will do 90 something cfm, with only 40 db. which is good for a 120mm

I know that an Adda 120mm ($20 canadian) puts out 108CFM...
Cheapo PSU fans push around 8 CFM most of the time.

[MiracleMan]

Argh! Only 8cfm? I can't believe this 80mm could be that lame!
Oh, yes, I'm looking for the silence side of things... ;)

[The Overclocker]

they are abit more then 8CFM, closer to 20CFM.

because the fins on radiators are quite close together the fans benift from having increased pressure caused by added depth. cheap fans do not work as well because they use slim (25mm) designs

[MiracleMan]

Oh well, and I forget to say I'm on the cheap side of things too! :beer:
And I'm in Brazil, and that's virtually inpossible to find Panaflows, Sanyo Denks etc... we have to fight all the odds to make things work here (or pay +$20 to get stuff shipped from USA)! :confused:

What works well for me, yet quiet is 2 of those panaflo 120x38 69cfm in a push-pull sandwich on the radiator and supplying the intake air for the case, 3 of those quiet panaflo 80x25 24cfm along with the PSU fan as exhaust.
