120mm Fan Testing on an MCR120 Radiator Round 6

[Martinm210]

Delta AFB1212VHE 38mm

Special thanks to Old Chap for sponsoring this fan..

I think I've found the GT of high speed, this fan has exemplary CFM/noise ratios at high speed!!

NOISE LEVEL
Nothing short of outstanding noise level per CFM, this fan is a good 5dbA lower in noise level than the best San Ace 109RH model and around 9 dbA lower in noise level than the Ultra Kaze 3000... wow

To rub salt in the wounds, the San Ace signs off at 61.5CFM, where this Delta model is just warming up...it carrys on clear to 82CFM...

NOISE QUALITY
This fan as most 38mm fan does have some ticking at very low voltages, but it seems to clean up pretty quickly in comparison. I would say it's mostly smooth by 6V and gone by 7V and of smooth noise the rest of the way. Granted any fan at 60+ dbA is what I would call very loud, this fan is doing much better than all the other 3000RPM capable fans in my opinion.

RANGE
1578-3843RPM is what I ended up getting when undervolting from 5V to 12V, pretty good.

KING OF POWER
By a fair margin, the strongest fan tested in this round so far.

INDUSTRIAL QUALITY
It's of very high industrial quality

OVERALL
This fan is the Gentle Typhoon of high speed fans, nothing short of amazing CFM per dbA ratios, and very good noise quality above about 6V. I'll give this fan two thumbs up for it's amazing CFM/noise ratio and awsome raw power.

Here is the link, but still processing...it should be up later tonight.
