On the topic of fan noise, I noticed that the fan by itself makes very little noise, although it does vibrate. Its only when it makes contact with something that can project the sound does it become annoying. Kinda similar to a tuning fork. Anyway, I mounted the fan onto a piece of sheet metal which is then attached to the bottom of the inside of the amp. The fan is isolated form the sheet metal with soft rubber gaskets on both sides. If you tighten it too much, compressing the gaskets and allowing the vibration to transmit, you will start to hear the fan noise. I was able to tighten it enough to keep it secure but not have any noise.
