Like Siegfried said, they can be mounted either way with no problems. You'll see the GT fans have quite a large following on the forums. They are good as case fans and as heatsink/radiator fans due to high static pressure. I think you'll enjoy having a case full of them, they are very good performers.

I tried the Enermax T.B. Silence and I liked the Scythe Kama Flow 2's much more than these. They push more air and are quieter (At least in my testing).

The Kama Flow 2 1900rpm model is tolerable at full tilt, but nearly inaudible at 1100rpms. I would highly suggest grabbing the lower RPM ones and/or getting the higher rpm ones and a fan controller.

I currently have 6 of these in my case and it's incredible how silent my rig is.

Interesting, I haven't used the Kama Flow fans. How would you describe the noise character? No clicking or anything?

Is their bearing suitable for horizontal mounting? I might try the 900rpm model as the bottom intake in my next case. (I love trying new fans <3).

How about the 135mm Kama Flex fans?

A few big, slower (> 1000rpm) 140mm fans will generally be quieter than 120mm fans moving the same air. Since you don't really care about static pressure with case fans, go with the quiet fans that can move the most air. This link may be valuable to you; the same site also has 120mm-only and 140mm-only fan round-ups as well. The top fans moving the most air quietly are Noiseblocker multiframe and blacksilent fans, Scythe Gentle Typhoons and S-Flex fans, and the Thermalright TR-FDB.

The conclusion page has some good info.

I suspect this depends on what kind of cooler your GPU has. On a card with a Twin Frozr cooler, for example, it vents most of the hot air out of the sides between the card and cooler; an intake would only be helpful if it was below the card's cooler so it can suck air upward, otherwise it would only push the heated air back to the card.

Definitely look into the info posted by BBEG. And the Kama Flow 2 is designed off of similar architecture of the S-Flex fans (Don't quote me, just what I've heard) which he says are listed as one of the top fans.

And I'm not quite sure how to define the noise character, but there is no clicking or anything, just the minimal noise of airflow. They mount great vertically or horizontally, I currently have 3 in either positions (Soon moving everything around but this is irrelevant). You will not regret buying them (Your wallet might though) .

I have 2 of these, at one point I had one mounted at an angle like this \\ , and it made clicking noises. I swapped it out with a Slipstream and haven't had an issue with the Slipstream clicking. The other Kama Flex I have mounted vertically and it's nice and quiet.

I run SLI with OCd Twin Frozr 580s and have a 166cfm 200mm side intake fan. My gpu temps never go above mid 60's.

You know what - I love you guys!

Just about to order a major upgrade so thanks for the invaluable insight.

*edit* I went ahead and bought 5x 120mm Scythe Gentle Typhoon 1450 rpm cooling fans. It should keep the new GPU happy hopefully

Thanks again!

How much did you pay for them each? I just grabbed two of the 1850rpm models and I paid a hefty price tag on them.
post #19 of 23
I paid $16 for my AP-15s, but I also had to wait a few weeks for them to arrive from a UK vendor. Couldn't find any State-side.

Boygor, do you have an idea of where you'll be putting the fans in that R3?

This seems counter-intuitive, but I won't argue with results. Have you tried turning the side intake into a side exhaust, or plugging the hole altogether?

Oh my question was directed towards Boygor, but damn I paid quite the premium over yours. I found one vendor that had them in the states but it's hard to admit that I just dished out $25 a fan .
