is anyone using these fans on their rad. im looking for opinions on noise (quiet system is #1 priority) and on performance. i would be putting these on my sig rig in a push/pull config.

now before everyone starts suggesting other fans, 25mm is the max thickness that will fit in my case, and i want them to be blue leds. these fans are also only $6 at svc.com and $10/fans is the most im willing to pay.

I'd use Zalman ZM-F3's instead. R4's aren't that good on a restrictive surface.

R4's have terrible static pressure. They're good for case fans, but not much else. I recommend Yate Loons. http://www.petrastechshop.com/12yalod1blle.html They have decent static pressure. The link is to Low speed, I'll try to find some medium or highs.

EDIT: here's some high speeds, http://www.frozencpu.com/products/61...2SH-124UB.html

the R4's vs yate loons of same cfm have 1.52mmH2O to 1.1mmH2O. do you know what the actual pressure is on those high speeds ones.

i found them in stock here

I have a bunch of these fans for my case and rad. They are pretty much the variable speed version of the R4s. What I noticed is that they really don't have the static pressure to push/pull the air - off the rad at max speed, you do notice a huge amount of air going through (albeit the high pitched noise) but when on the rad, it doesn't have the strength to pull even nearly as much air.

The ones that I had as case fans are great though, so I have to agree with others: case fans - yes, rad fans - not the best option.

Btw, the static pressure that CM posts for these fans (5.6mm H2O or smth) is nowhere near what it really is. Same for noise - at 1900rpm it is definitely way louder than 19dBa.

Hope this helps.

EDIT: For what you're looking for, here are some High Speed Yate Loons if you don't care about the noise, and low and mid speed if noise is a concern.

I am using them with my GTX 240 and I am getting horrible temps (Maybe due to the fans or the horrible GTZ block with dings) So I would suggest no don't use them.
