120mm Fan Testing on an MCR120 Radiator Round 6

[Martinm210]

San Ace 9S1212M401 25mm Medium Speed

Special thanks to the finisher for sponsoring this fan..

The is very similar to the 9S1212H4011 except it turns at a lower speeds.

NOISE LEVEL
It's fairly close to the yate medium, very slightly higher at slower speeds and slightly lower at higher speeds. Relative to the rest of the fans tested so far it's about average.

NOISE QUALITY
I think 4,5,6V was about average and 7-12V was very good. Generally has a good smooth sound without any resonance or motor ticks. The lower volts just had a little roughness compared to the higher range is all, but generally a good smooth sound of air/wind/turbulence for the most part and nothing obvious or sharp like a motor tick or resonance.

OVERALL
It's a very well built industrial quality fan with about average noise level and average to better than average noise quality.

COMPARED TO ALL FANS TESTED SO FAR

Well then, I suppose I'm happy I never invested in the Sanyo Silent series. It's a good thing I'm cheap The performance seems acceptable, but not for that price...

I'm cheap too, and why I ordered the next contender...
