Another fan sponsored by Shazza

Since Shazza let me pick the fans, this was just one of those grabs because of the batwing blades. I also noticed the blade is removable so I was curious how it did.

NOISE LEVEL
It was about 1-2 dbA higher than the yate medium.

NOISE QUALITY
Very good, no apparent or obvious motor noises, ticks, or resonance peaks.

EFFICIENCY
Not quite as efficient as the yate medium, but close and still kept it under 2W at 12V.

CFM per RPM
Not quite as good as the yate medium. Not sure the bat-wing style is the most efficient, but perhaps it gives it that smoother air sound.

OVERALL
I liked the smooth sound, but it was a higher noise level than the yate medium. Removable blade might come in handy for cleaning or adding lube to the bearing long term.
