I needed a slim fan to fit in the front of my PC case. I wasn't particularly bothered about how loud it was but after fitting it is running quietly. It's a 3 pin fitting so I cannot adjust the fan speed but for creating a bit of airflow through my PC case, and for such a low price, I think it's a great product.

Great little fans. Love the look of them and at 15mm thick they are just slim enough to fit my case.
While the performance obviously won't be as good as standard width fans, it is very good for a fan of this thickness and moves a good amount of air.
They run quietly (not at full load) and I've had no issues running them at low voltage.

My only real criticism is the ugly red/yellow cable. Sleeve it, colour it black, wrap it, whatever but leaving it like that makes the fan seem like it is poorer quality than it really is. Not a big issue but aesthetics are important in a pc too and shouldn't be overlooked

Great fans, nice and quiet, supplied with anti vibration rubber mount and metal screws, (can use either) and a 4 pin molex converter.
Also provided was a small 4 pin cable, I mistook this as an extension cable, it is however a speed reduction cable.

These are the best for the office, just enough air to keep cool, quiet and very long lasting product.

Works very well. Runs very quietly.

Thes fans are quiet, and I really like them. You get a short extension cable in the box with a resistor inline that reduces the voltage the fan gets, which makes it pretty much silent due to the reduction in speed. Everything is curved in the airflow too, which is Silverstone's attempt to reduce noise, as straight lines are apparently more noisy than curved ones when it comes to grilles. I have their GD08 HTPC case too, and that ethos is demonstrated there too.
