We should probably start a separate pump noise thread rather than "spam" up this one.

However...

In my experience pump noise can be dramatically reduced (or even removed) with the correct mounting.

The best method I have found to isolate the pump is to suspend it from string (using an old HDD cage) although in my latest build I have used cut up tube to isolate the pump which also works well.
Foam isnt very effective in my experience.
