Summary: Very simple installation (it is only a fan though!) and extremely quiet at 300rpm. However if they get up to 1300rpm you will definitely hear them - not an awful noise, but quite loud if you expect silence! Cables are quite long: 28cm for RPM cable (single into 3-pin) and 28cm for PWM cable with an extra 7cm for the extension to the next PWM fan.
Summary: Not much to say hear buy this fan looks sexy in the case, is very quiet and comes with a 6 year warranty. Be warned, this fan can only be used as a exhaust fan in the case; if you're looking to buy this fan to be used as an intake fan for your case it will NOT mount.
Pros: Price, quiet, looks and brand., 6 year warranty.
Summary: The Good: Quality PWM fans at a great price. I was looking at much more expensive fans just because they were what everyone else has been using. I'm so glad I took the time to research Arctic Cooling products. These fans are high quality and have features of much more expensive fans.
Summary: I brought 2 of these to replace my 2 Xilence wings fans which were super quiet but suffered drastically in pushing and pulling air.
Any how, once installed the temp of the case dropped dramatically as well as being able to blow cool air to the back of the case which is a mega bonus
I would highly recommend these
