Help with rad fans

[metro.cl]

I got a swiftech 2x120mm rad here for my new watercooling set up, and i'm looking for some powerfull fans for it.

I saw this ones:

Scythe 133CFM 120x120
http://www.petrastechshop.com/12x38scdfuka2.html

Delta 185CFM but 127x127mm
http://www.petrastechshop.com/12x38deefcaf1.html

Delta 120CFM
http://www.petrastechshop.com/12x38deefcaf.html

Now i would take the 185CFM model but im not sure if it will fit 120x120 fan holes to screw in the rad, if it doesnt, should i take the Scythe or the Delta 120CFM?

It has to be from petrashop

Did some math, and the distance between fan holes on the Swiftech rads is 19mm, the amount of room you need to mount the 185CFM Delta's is 22. 2mm,...so, no fit for you!

Of the other 2 fans listed, looks to be evenly matched. The Scythe appears to have a static pressure of 88.66Pa in a review I found, and the Delta has a static pressure of 10.90mm H2O. Now you can't evenly compare the different scales but we can convert them. I found a converter that does this online and Petra's Pa # is just a wee tad off (it's actually supposed to be "IN H2O"), as the converter gave me a 106.9Pa. The Scythe has a RPM wire whereas the Delta lacking this feature. The Scythe also makes a tad less noise and is also $3 cheaper. I'd have to go with the Scythe myself as the extra pressure provided by the Delta couldn't overcome the noise, price, feature handicaps IMO.

wow pretty noisemakers...

i'd probably go with the scythe's also and under volt them... or you could try emailing Quoc and ask about Sanyo Denki San Aces if he has any... you never now until you try.

also note that PTS website is not always updated, for instance they already have EK anti cyclone plate available, but not on the website yet...
