Scythe Ultra Kaze 2000
Yet another fan sponsored by Shazza
I've used the UK3 in previous radiator testing and alway thought they were a great value fan for high speeds, but they had a tendency to tick when undervolted....so I wanted to try the UK2. The good news is the fan is much better with the ticking problem I think is more apparent in the UK3.
In general I thought it has a bit more motor whine than 25mm fans at similar performance levels, but slightly less wind/blade type noise.
It actually performed fairly similarly to the yate medium speed 25mm fan with the exception of a few bad voltage spikes. It seemed to resonate at around 5V, 8V, and 10V with about a 1-3dbA spike over the normal trend with the biggest spike at 8V.
As far as CFM/RPM it does very well, a bit better than the yate 25mm fans. The fan is also more electrically efficient drawing about .5 watts less than the 25mm yate medium.
Overall a pretty good value fan for higher speeds, but if you plan to run lower than about 1700RPM, you'd be better off with a 25mm fan. If you do undervolt, you may want to tune off of those resonating points.I also thought the motor sound was a bit whiny in general at lower volts.
