Last week I finally replaced this ancient beast with a Fractal Design Define R4 silent PC case, which came with two of Fractal Design's own 140mm case fans, one fitted at the front (intake) and one at the back (exhaust). Being unfamiliar with Fractal Design's fans, and being naturally suspicious of manufacturers pushing their own accessories as 'freebies' with their main product, I was expecting having to replace these 'free' fans with Scythe equivalents.
To my pleasant surprise, however, I find them to be at least as quiet as my Scythe Kama Flow2 fans, so I have since ordered another Fractal Design Silent Series 140mm case fan and fitted it in the second slot in the front to keep my seven hard drives cool.Read more ›
Running at 7v, you can only just hear the fan if you put your ear right next to it.
I installed this in a Coolermaster elite 110 case (mini itx) to replace the noisy 120mm fan it came with.
Highly impressed, great airflow and dead silent, cant fault it. Would recommended to anyone looking to build a quite system.
Regarding installation, the rubber fittings are best, but, a pain to install.
Once most of the rubber fitting is pushed into the fan, I'd recommend using a phillips screwdriver to push the remaining part of the rubber fitting tightly in place.
Comes with 4 rubber "screws" and 4 normal screws - I use the normal screws on the roof of my case, I just don't trust the rubber ones with... well, gravity, essentially. Maybe I'm just paranoid. Also comes with what looks to be an "extension cable" ? Could be completely wrong, though.
Some fans give people a headache from the noise they produce when horizontal (ie, on the roof/floor of the case) - no such issues with these.
Inside the box you receive:
Screws, black in colour and fit all mounting points on fractal cases and are of suitable quality.
Rubber noise dampening standoffs, good to use where you can but I could only mount one fan with them as they are too difficult to install in thigh corners of your case also don't make much difference to noise.
Low noise resistor, Good quality full black and sleeved. good if you don't have a fan controller but most fractal cases have one built in and they make a mess of any lovely cable management if mounting on your motherboard. Does lower the noise but your better of with a fan controller.
Fan, good looks with the two tone black and white and would fit into most cases. Good pressure output for radiators* (most radiators are 120mm). They output little noise when on half power (500-600RPM), on full power you will notice the noise generated but it is manageable with a good case.
Highest RPM achieved: 1200RPM

Virtually silent and very fast. Great airflow. It made a difference of 2 degrees C to my gpu (nvidia 650ti) under load. Would highly recommend!Published 13 months ago by Abel S.
