I recently posted (http://www.xtremesystems.org/forums/showthread.php?t=162307) about a new line of Scythe fans the Ultra Kaze. When I posted the link I purchased the 2000RPM model from www.aerocooler.com. The transaction when smoothly and I received my fan Thursay October, 18th.
Currently I am using a Thermaltake 120MM Smart Case Fan mounted on a Thermalright XP-120. With TT's rheostat I am able to control the fan from 1300RPM up to 2700RPM. For day to day use I kept the fan at 1800RPM because that offered an acceptable amount of cooling and noise. Upon ordering the Scythe Ultra Kaze 2000RPM I set my Thermaltake Smart Case Fan to 2000RPM and ran some tests. The results will be included.
Here is a picture of the XP-120, it seems like the fins are fairly close together and the added static pressure that Scythe promises (http://www.techpowerup.com/img/07-10-15/Scythe-Static-Pressure-Comparison.jpg) might of benefit.

Some of the pictures are blurry, I borrowed the camera so I don't know all the tricks to make close up shots clean and crisp.

The Test
For the test I ran OCCT and allowed Everest Ultimate to montitor the temperatures. Before I ran OCCT I opened Everest's Monitoring tab to see what the RPM the fans were reporting.

Noise
For this test I tried to isolate the fan from background noise and other sounds that may affect the test. I used an old PS2 SOCOM microphone along with Nero 8 WaveEditor to record 5 second clips of the fan. I positioned the microphone 5 inches away from the fan pulling in air. Because of the forum file upload limitation I had to compress the .wav files to .mp3 format. I used Nero 8's LAME profile to compress the audio files. Download the files, extract them and listen for yourself. Subjectively I would say that the Thermaltake fan at 2000 RPM has a higher pitch than the Scythe running at 12V.

Conclusion
Well there you have it. The Scythe doesn't seem to perform as well as the Thermaltake fan set to 2000RPM. While the TT fan was spinning faster than the Scythe the few extra degrees is not worth putting the TT fan back in my machine. On the plus side the Scythe fan is quieter than the TT fan at roughly the same RPM. There is the information for you to look at and now you can decide if you want buy some Scythe Ultra Kaze fans. Only time will tell now if the sleeve bearing gets louder and how long the fan will last.
