I've got my eyes on Scythe S-Flex 800 RPM, but I've also heard a few rumors about some "ticking" or something.. I might be willing to take the risk though. It performed very similar to Noctua's fans in this test: http://www.silentpcreview.com/article695-page5.html#sflex - but listening to the audio recording I found the Scythe tone more "flowing" if you know what I mean.

Any other suggestions or any comments for any existing Scythe/Noctua users? :)

The S-Flex fans ticked on my eVga 680i board but not my Gigabyte P45 board.

Scythe has a new fan out, slipstream and its very good. I'd recommend that. I put one on over my old S-Flex and it lowered my CPU temp ~8C

I have a Scythe that came with my TRUE120. It's very quiet on low to mid, on high it's loud, but I have a silent system so anything will be noticeable.

Wow thanks for bringing that to my attention; I just checked out the apparently latest fan roundup (http://www.silentpcreview.com/article832-page3.html) and it apperas that Slipstream is not only a tiny bit more efficient but also half the price of S-Flex. Sweet, thanks for the headsup :)

I have question though, how is it that you underpower the fans to less RPM and noise levels? The only available Scythe Slipstream fan in my country at the moment is the M model that runs at 12V/1200RPM//46CFM/28dBA at default.

You just hook it up to a fan controller or to a fan header on your motherboard. Basically what you're doing with a fan controller is just lowering the voltage, which causes it to run slower. The same thing is done when changing the fan speed in the bios, it is just done digitally.

I'll have to take a look at the slipstream. I have a bunch of S-flex 1200rpm fans right now. None of them "tick" and they are pretty quiet.

Sycthe D's are good
So are Yate Loon low speeds
Stay away from SilenX
Noctuas are ugly but very solid and quite fans

If you really want control over noise/performance then you must get a decent controller.

Go for the KAZE Master ACE. Its killer.

Looks interesting. Though I call bull**** on those specs until I see an objective measured test. The specs from these I just found when googling looks even more bull****: http://www.silenx.com/ixtremaprofans.asp

I run the D12SM-12s and the D12SL-12's, they do hum but they aren't loud by any means in my opinion. I have the Ultra Kazes too, and those things push a ton of air but are loud as hell and they do not take undervolting too well.

The Scythe S-Flex line is really good, I have the SFF21Es, G's and F's these things are QUIET and have a great cfm/db ratio.

The s-flex's are great for medium airflow and silence.

i use a s-flex with my tuniq tower. very quiet and the sony-made bearings last a long time and make the fan noise sound different than crappy sleeve bearing fans. much more tolerable on the ears.
