Building a Silent Workstation

The purpose of this paper is to describe how to build a silent workstation. By silent, I mean inaudible in an office with a closed door, or in a suburban home. These are locations with fairly low background noise levels (40dBA - 45dBA). Lowering the noise level of a computer, especially a high-performance computer, to be inaudible under these conditions is a significant task. Keeping the component temperatures low enough to deliver a long life can be even more difficult.

Assembly

The power supply was the first thing to be paced into the case. No problems were encountered. The power drops were temporarily run out the back of the case, to keep them out of the way while the rest of the components were installed.

The CPU and heatsink were placed on the motherboard prior to installation into the case. The heatsink had to be mounted before the motherboard could be installed in the case, as it has a backplate (part of the bolt-through kit).

It's time to add the heatsink.

In this orientation, the heatsink is a bit too close to the 16-lane slot, and to the first memory slot. This also shows that the Scythe Ninja (similar in width to the Thermalright HR-01 Plus) would be too tight of a fit, as would other heatsinks of a similar size (which includes all of the heatsinks with a 120MM downward-facing fan).

We rotated the heatsink, and there's now quite a bit of space around it. Memory is easy to access, and the video card is unobstructed.

After the motherboard has been installed in the case, it is necessary to block the openings above the expansion card slots. This space was opened up (perforated) by Antec. In a case with more air being blown in than out, this works fine. Unfortunately, it's difficult to achieve that state with the Solo. Leaving these openings unchanged allows heated exhaust air from the back of the system to be drawn back in. Blocking these openings (I used some packing tape) causes the additional air to come in from the front of the case.
