Rosewill Black Medium Speed

This fan came out of a rosewill challenger case I bought on egg for my son's computer I built from leftover parts. The fan itself has nice curved blades and doesn't look all that different from a normal yate loon.

But that's where the similarities end...

NOISE LEVEL
About as bad as it gets, it was right up there with the worst of the worst.

NOISE QUALITY
Also very poor, while 4 and 5 volts was relatively smooth 6 & 7 volts had pretty strong harmonics, and medium to high volts also included a pretty strong motor tick. Not good.

EFFICIENCY
Fairly poor compared to the yate loons high quality

CFM per RPM
Suprisingly also fairly poor compared to the yate.

OVERALL
Poor. I really hoped this budget fan would be another option to the yate, but it's not. It might get you by in a pinch, but I wouldn't recommend this fan..it just did not do well on a radiator..
