Scythe Ultra Kaze 3000

I've had and used these fans for my past radiator testing, they are a good value fan for 3000RPM speeds, but...like most ultra high speed fans...have a strong tick when undervolted.

NOISE LEVEL
About average, slightly higher than the yate medium and about 1dBA higher than the Panaflo U.

NOISE QUALITY
Poor when undervolted, it has that typical 38mm fan tick when undervolted although I'd subjectivly say it's not as strong as the panaflo. Still not going to be anywhere nearly as smooth as a good 25mm fan at lower speeds.

**Bing has noted that a good PWM controller may go a long way in eliminating the motor tick. I will check into this. If I can build a remote (no computer necessary) PWM controller, I will retest..

EFFICIENCY/POWER CONSUMPTION
Seems to match pretty well with the Yate down low, but it extends that trend a LONG ways up there, drawing about 7 watts at 12V, so make sure you're watching and looking at your fan controller specs. Many fan controllers can only handle 20 watts or so, so you could easily exceed that amount with just 3 fans in series causing failure in the controller.

RANGE
Exceptionally good RPM range from 950RPM to 3000RPM.

OVERALL
A good value 3000RPM fan, but it's very ticky at lower volts. The Ultra Kaze 2000 is much better on the motor tick, but not nearly as smooth as some 25mm fans. I would recommend using the fan at 12V and leave it there if you can handle the noise level.

Bottom line, good value 3000RPM fan, but noise quality suffers when undervolted.
