Noise Level Results
Part of the reason the temperatures were so high is that the move to achieve silence has won over the need for performance. With the CPU idling and 7.5V running to both fans I got a sound level result of 29dB, which is barely audible.
Sound levels do jump a bit when 12V is pushed to them, but even here they only come up combined to deliver 51dB of noise level. The nice thing is you have to be in front or behind it to get that level, from the sides it is much quieter, so once in a case this should be a very mild hum to deal with.
