Depends on which Scythe GT and GELID fans you're referring to. I only compare apples to apples, meaning both fans have to have similar RPMs. I tried the AP-15 (1850rpm), AP-45 (2150rpm) and GELID's PWM Wing 12 PL (1800rpm). The AP-45 matches the GELID PWM in static pressure, but at a 350rpm difference and much higher noise level. The pressure on the AP-15 feels noticeably less than the GELID PWM, not surprising since the sp rating on the AP-15 is 0.081inH2O or 2.05mmAq (0.081 * 25.4).
I kept my search for 120mm narrow. I focused on fans between 1500rpm - 2000rpm (+-200rpm) or had a very good static pressure rating (2.0+). Here are all the brands I've sample before settling with GELID's PWM, keep in mind that I had strong preference towards the AP-15 and Noctuas since so many people rave about them on forums, but in the end I can't deny the science.
Noiseblocker M12-P, Cougar CF-V12HP, Noctua NF-F12 PWM, GELID Wing 12 PL, Scythe AP-15 & AP-45 and bequiet! SW1 (2200rpm)

I know I don't hold all the knowledge about fans, but I own 4x NF-P12 PWMs and they really have blown all the other fans I've bought out of the water. (I'm one of those guys to blow hundreds on pointless things like case fans (yes I said pointless because in my case, they are, pun not intended). I don't know how other Noctua fans compare, but these are near silent and they push a good amount of air. I've tried sleeved bearing, ball bearing, and now this SSO bearing (is it just a proprietary FDB?). Are you buying stuff like San Aces or Delta fans? My Megaflow 200's are $17-20, depending on where you buy them, a piece.
I can't help but to question the legitimacy of your claims of "blowing 100s of $$$ on case fans" when you fail to come up with a specific amount because normally when people are making stuff up they unconsciously use very broad and general terms like "100s of dollars". Few other things I find questionable is how you claim to spend 100s of $$$ on case fans when your case is only worth $160. And how did you acquire your volume license key for Windows 7 Enterprise? Do you own a business with over 250 PCs?
San Aces and Delta? Ummm, my whole discussion so far has been about noise, why would any noise conscious person use server grade fans?
The noise on those are unbearable unless you have your setup where the tower is in another room, but since you brought it up, I never experienced San Ace fans but I did try 2x Delta TFB1212GHE 120x38mm just for giggles, because 26.44mmAq of static pressure was just too tempting not to try, not to mention the sound of two 4600rpm fans on full blast.
Don't mean to belittle 200mm+ size fans, but they do virtually next to nothing other than waste electricity while inefficiently occupying space they're mounted on. The current state of giant size case fans are aesthetics and does next to nothing in terms of cooling. However, if they made a 200mm x 50mm intake fan @ 1600rpm then we'd see some real performance, but until then……

Relatively very good acoustics though. As always, there can be differences in samples and performance in different environments.
The non-PWM version is a waste of time if you're planning to use it on a heatsink. The PWM version spins 300rpm higher at 1800rpm and has a static pressure of 2.66mmAq vs 1500rpm version with 1.925mmAq. That's quite significant difference in static pressure and when it comes to heatsinks and radiators, it's all about static pressure.

If I'm being completely honest, I swear the Scythe's are pushing more air (and with less noise) than my Noctuas.
If you're referring to the AP-15 then the fact is, they are pushing more air. Mainly because the GT series uses a heavier blade vs other case fans.Edited by barcode71 - 3/15/14 at 12:46am
