Iâ€™ve been doing the quiet computing thing for a while, and this is my first rig Iâ€™d consider silent. It could be quieter (cutting the fan grills, more HDD dampening), but it runs 24/7 in my closet negating the need to go much further in the silencing.

The cooling of the computer is controlled by a Scythe Kaze Server fan controller. It offers more adjustability then any hardware based controller Iâ€™ve seen, has analog outputs for lower noise, and is actually a PI if not a PID controller. If any of you have ever done anything with control systems, the advantage of this in a quiet apparent.
In the picture above, the controller is displaying (from left to right) CPU temperature and rear exhaust speed, northbridge temperature, HDD temperature and intake fan speed, and PSU temperature with PSU heat sync fan speed. All but the northbridge are set to â€œsimi-autoâ€
