Awesome results!

It seems as through the added thickness of these fans isn't paying off on the low restriction MCR120 tests, hopefully the 38mm fans will make a comeback and show their power when tested with the GTX 120?

Yeah, 38mm isn't the cure all it seems. We always think 38mm = higher pressure than a 25mm fan which is not the case in the yate loon. For every RPM the 25mm yate produces more air through the rad than the 38mm variety.

I think it's probably due to the larger fan hub leaving less blade surface area, but I'm not sure..

Enermax Magma

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.:shrug:

Loving all the testing your doing, from all your data it seems that so far the Yate Loon is still the best fan.

I'm just using the Yate Medium as my baseline comparison. There are better. The Zalman is slightly better and I expect the GT will be as well...hope to find more as well.

Too bad you couldn't asked reaper to donate you some GT 2150RPM and GT 3000RPM fans. He bought them on the Nidec website with bare wires, so he had to install those 3 pin headers.

Gelid Silent 12

Special thanks to charliehorse55 for sponsoring this fan..

It's a PWM fan and seem to exhibit some odd behavior for start up. It did not want to start any earlier than 6V and both 6 and 7V were really low RPM, then suddenly a big hop up at 8V. In the end, I really only was able to produce good results for 8, 9, 10, 11, and 12V.

Those results were fairly similar to a Yate medium with about .5 to 1dBA higher noise level. Noise quality was ok, nothing major bad jumping out at me, but also nothing really special in smoothness.

I do like the looks of the white on black though. It also didn't quite scale as high in performance as the yate medium, so it's really geared for low/mid RPM duties.

Overall did ok, similar to a yate medium with lower top end RPM and PWM ability.

Yate Loon D12SL-12 from P.T.S.

This is a fan I had lying around for a while, bought at Petra's since they had the better higher quality yates.

Yates have been known as an exceptional value fan for some time, and I have used them on several builds myself.

The finish of the fan is generally a little low, the stickers are never on centered and it seems like the blades are not quite balance, but in the end they do really well from a noise/CFM perspective. They also do not come with wire sleeving or any accessories...not even a box. They are basically an OEM type package, fan only.

Regardless of the absent package, the fan does really well. No apparent undervolting issues, no harsh vibrations or motor ticks, and a relatively good sound. Perhaps not a smooth in sound as some other, but the noise level is low and consistent throughout the voltage range.

My results had this fan pretty well matching the medium speed model with perhaps slightly lower noise levels. I say perhaps because 1dBA is possibly within testing error and 3dBA is considered barely perceptible. Personally, I can't tell the difference between the SM and SL models at like performance levels.

Previously I had thought the SM was better than the SL, but with this I think they are the same.

This fan gets my "Amazing Value" thumbs up.. ...
