120mm Fan Testing on an MCR120 Radiator Round 6

[Martinm210]

Triebwerk TK-122 Mid Speed Fan

Special thanks to AceBaran for sponsoring this fan..

NOISE LEVEL
Very good, particularly at higher speeds. It was roughly matching the yate medium at it's lowest 4V setting improves to about 2dbA lower than the yate medium at the upper end with the exception of a resonance bump at 9V. Relative to the mass of fans tested so far, the noise level is a fair amount better than average and leading at the 2000RPM level.

NOISE QUALITY
Variable. I think it has good noise quality at higher speeds, but I do hear a little motor noise at lower volts and there is one small resonance bump picked up at 9V on this particular test setup. It is probably the best 38mm or wider fan tested so far. Because this fan has a smaller than typical hub, it seems to sound more like a 25mm fan motor than that of a large hub 38mm fan and has less of an issue with motor tick than most 38mm fans do at lower volts.

FEATURES
This fan was specifically made for water coolers, so it has a fair number of features worthy of note. The rubber mounting system is exceptionally good and completely isolates the fan from hard surfaces including the screw. The noiseblocker S3 was the only other fan to incorporate a system quite this good. The fan also has a built in shroud for pull condition, a special daisy chain feature for connecting more than one fan without all the cable mess, and M3 and M4 screws. My only complaint is no 6-32 screws for radiators like the MCR120. The fan also has a metal wire frame and a cone shaped hub nose which should all help reduce the dead spot on radiators.

RANGE
Very good range, starts up at 4V or 830RPM and runs clear up to 2010RPM, so lots of RPM options.

THICKNESS
This could be good or bad, depending on your needs and preferences. I personally like the looks of the extra thickness for external setup, but this could also be a limiting factor on many internal setups where space is at a premium. At 55mm, it's over double your normal 25mm thickness fan.

VISUAL
I do like the looks of this fan. Probably my favorite looking fan, just because it's so unique and massive.

COST
At $19 each at SWC, they are definitely a high cost fan, although there are several other fans that cost even more.

OVERALL
A very good noise level fan particularly at higher speeds, with a very good 800-2000RPM range, variable noise quality, lots of unique features, and high cost.

I'll give the fan a thumbs up for it's mounting system, daisy chain feature..and it's 2000RPM low noise level/quality..
