Best fans for radiators?

post #1 of 28
Thread Starter 
Hey guys,

Am just wondering what the opinion is of these Koolance fans, FAN-12025HBK?

I'll need 18, or 36 if I go Push/Pull, for 5 radiators. 3 120.4's and 2 120.3's. The reason I've chosen these one's so far is because of the small things like 32.8dBA at 2600RPM's biggrin.gif and 5.4mm pressure (I've heard that's needed/better for rad's?). If anybody knows of some better fans, please lemme know! thumb.gif

P.S: I'm not building this rig anytime soon (in sig rig), I don't exactly have $14-odd thousand laying around in spare cash or change, hahaha tongue.gif I'm waiting for the Kepler 680 and to see if the LGA2011 Ivy is any good, plus it's always good to be prepared and gives me plenty of time to find the best WC'ing loops and placement of things.

Cheers. thumbsupsmiley.png

People rave about Gentle Typhoons.

Are you going for pure performance, low noise or a compromise?

For pure power, Deltas are probably the way forward. For silence, any fan under 1000RPM is going to be fairly quiet. For noise / performance you just can't beat the Scythe GTs at the moment. I have yet to seem them put up against the new Noctua NF-F12 (hoping it is a lot better than the P12) or Swiftech's new Helix fan so that may change soon, but I doubt it will be by much.

Oh, and take the manufacturer's specs with a large grain of salt, they often have a very liberal interpretation of testing procedures.

For me, personally, noise isn't really a problem/factor. As I listen to music most of the time I'm on the PC, and for low pc usage I can just turn all the fans down. But yea, noise doesn't phase me as I play with a 7.2 surround system and such.

So I guess, pure performance would be what I'm after. I plan to do some serious overclocking of the 3960X (or Ivy equivalent) and three 680's (or 580 counterparts).

Yea, I know. I just looked at a youtube vid of the 12025HBK but it's almost impossible to gauge the sound of fans online because of volume levels, and mic quality. Seen a few posts here and there about them though, some say they're great for rad's but are a little on the noisy side. but as I said, that's fine with me.

I'll look around for the fans that have been mentioned here and see what comes of it.

I have three 2200 RPM versions of these fans on a koolance 360 rad with a high fin per inch count and I'm satisfied with the performance. The noise is low compared to the stock GPU fan and H50 cooler but what wouldn't be. If your gonna get a fan controller they're probably OK but I'm sure you could find the yates cheaper though. Also you need to keep in mind your fins per inch on your rad, that will have alot to do that you will need high or low fan speed.

Gentle typhoons are the way to go. They deliver great performance and sound great. I would check out the AP-15 version. Would be a great pick for your setup.

Rad's I'll be using are the Black Ice GTX 480(3) and 360's(2). Apparently they're both 20 FPI. Not sure what to make of that, though... you tell me tongue.gif lol.

Oh, and anybody know if these actually do help at all? Phobya Plexi Radiator Shroud

Yes I know they're for 140mm's but I'm sure if I looked I could source the 120's from somewhere...
post #10 of 28
Shrouds help eliminate dead spots from the hubs of the fans,(good thing). 20 FPI is about med density so 1000-1800 RPM fans will probably be about the sweet spot for max performance as more RPMs wont be as effective.
