120mm Fan Testing on an MCR120 Radiator Round 6

[Martinm210]

Gentle Typhoon AP-13 (Old Batch?)

Another thanks to Vapor for sponsoring this fan..

With the 15 and 14 doing well, I figured the 13 would follow suit and it does.

NOISE LEVEL
It falls pretty much in line with the AP-14 in being one the the very lowest noise/CFM levels for it's range, although there was a little bump at 9V.

NOISE QUALITY
It's fairly good like the other GTs, but I think at these really low RPM levels the ball bearings start to become one of the more pronounced noises. Some of the other sleeve or FDB (Sleeve variants) don't have that. It's really quiet and minor, but I think as you approach the 1000RPM and below range some of the other options begin to look more promising. I'll call it average to above average since there isn't any motor tick, but some ball bearing noise. I did find one little resonance bump at 9V, but it's pretty hard to detect other than the sound meter picking it up.

RELATIVE TO THE GT14 & GT15
I think it's roughly the same as the GT14, and a hair better than the GT15 at like performance levels. The GT15 seems to have more problems with resonance bumps than the lower speed family. This could all be sample variation, but what I've seen so far.

OVERALL
Very very good at 12V with a dbA level about 4-5 dbA lower than most fans, but that slowly diminishes as you lower the RPM levels. I think once you get down to about 800RPM, it's no longer doing any better than many other fans if you consider both noise level and noise quality. Some of the other fans have quieter bearings using sleeve, or FDB. With that said, it's still doing a fair amount better than the others at 12V or 1200RPM. It gets fairly competitive below about 800-1000RPM.

I'll give it a thumbs up for really low noise/cfm ratios from 1000-1200RPM.
