The results of our load tests show that the 80% fan speed setting is the sweet spot, at least in terms of overall noise. Of greater interest is the sizable cooling improvement as the system fan speeds are increased with the CPU temperature dropping 4°C going from 60% to 80%, with another 3°C reduction at 100%. A 1~2°C decrease is more typical with ATX towers, even with models with more than two fans. However, the GPU fan speeds required to achieve the target temperature are fairly high at each level.

All together, this suggests that the P100 would benefit from having an additional fan, and that the exhaust fan may be more effective than the intake fan, due to the fixed drive cage getting in the way. I later found that removing the front filter had no effect on performance (incredibly rare!), confirming that the front intake vents aren't the issue. The open sides behind the door are a great way to feed fresh air into the system.

On load, the effect of a higher CPU fan speed and the GPU fans spinning up, doesn't affect the overall sound quality greatly. The video card fans give the machine a rougher character but the system doesn't sound at all unpleasant, aside from the actual volume.

Compared to previously tested budget cases, the P100 generates middling temperatures at a slightly higher noise level. For our system configuration, it's not efficient as the SilverStone KL05 or the Fractal Define S. It's notable that every other case tested had an open space at the front directly next to the video card which obviously allows for better airflow, suggesting again, that the impedance of the P100's fixed cage is the likely cause for its somewhat higher temperatures.
