Not silent - but very quiet
I've installed 2 of these to replace the stock fans in a Fractal Design R3 case - which were quite intrusive. The result is a much quieter PC that now just emits a low frequency noise rather than the whine and buzz of the stock fans.
Looked at it the wrong way and one of the spokes fell off. Solved the resulting vibration problem by letting it hang nonchalantly from a single plastic fastener, where it swings back and forth looking preposterous while reducing the case temperature by a few degrees. I've given it 10 out of 10, as it's the best swinging, spoke-challenged fan in its class.
Many thanks for the humorous review and sorry to hear about the fan. If you would like it to be replaced under warranty do get in touch.
Can't believe I didn't upgrade sooner. This is very, very quiet, easy to install and comes with all the bits you are likely to need. Highly recommended. Also the postage of the item was super quick, thanks Quiet PC!
I currently have two of these connected to my fan controller and I can get RPMs down to 260- at these speeds they really are silent, even with your head directly next to the case. Naturally, airflow suffers at this RPM but as most of us know, just a little airflow makes all the difference over HDDs etc
When cranked right up they are noticeable but never really distracting. It's a very 'even' sound that most people would get accustomed to. In all practicality, you would only ever need to turn these right up when gaming. You then wouldn't be able to hear them over the sounds from your game so this shouldn't matter on a day-to-day basis.
In an Antec P183 case (as is the case with my set up) with it's excellent sound dampening properties, you could easily afford to have these at a respectable RPM without noticing a difference in noise levels.
To summarise, this is a perfect case fan if you want silence at the expense of high airflow.
