Had my previous housing already outrageously expensive and highly praised 120mm Nocuta had fans that I had to go back immediately because of the noise 45 ° at the outlet side and given the price miserable processing.
A comparison of the technical data of NDS140-1100 with competitors showed (apart from the life of) an unbeatable price / performance ratio.
In short:
+ No annoying humming noise
- Drive is in the lower speed range (at 7V) at a certain temperature softly Tickergeräsuche of himself'm sure if that was not the case at room temperature or contaminated system.
+ Sleeve makes a decent impression, compared with cash BeQuiet
+ @ 12V / 1100rpm only 14.4 dB (A)
o life 80,000 hours, according Nanoxia
o 7V resistance adapter has white connector and no Sleeve
Appearance
The fans have black 3-pin molex connector, the harness has a high quality and robust-sounding black Sleeve comparable to those of BeQuiet power supplies.
The fan chassis is made of black plastic, the struts slightly soft, which indeed seems cheap, but a very positive effect on the attenuation of structure-borne noise from the drive.
Remarkably, that a manufacturer has got it at a ~ 10-silent fans that the distance between the propeller and the housing must be evenly all around, many fans are flattened at the even-numbered pages on the inside, so that the turbulence will be compressed on the wing tips on reaching the flat area what has annoying induce hum.
The propeller is made of green colored Makrolon, slightly uneven surface, but when you look else please NEN standing fan.
Conclusion
Who wants to have a lot of capacity in as little dB for narrow money is perfectly consult with the NDS 140-1100.
