gregkwaste - if your H80 was rattling in the upwards position and stopped when tilting the case, that's the bearing issue. Now if you move the radiator below the pump, the air will go to the pump, which might stop the rattling, but in turn you will have worse cooling efficiency.
If you want to experiment, you can get a 3-pin to 4-pin adapter and use a motherboard fan header instead of a fan controller. However if you get a fan controller, make sure it's not a PWM controller (like the one the H80 uses for its fans) but a normal voltage controller. Zalman FanMate might work, it's a simple as it gets. Sunbeam Rheostat would be a next step up, but it uses the same basic functionality, a potentiometer on a base of a power transistor. The downside of those controllers is that they have a scale of 0V to (about) 12V, so the range of your interest, 10V to 12V, will be just a little turn of the knob, so not much precision there: http://www.silentpcreview.com/article84-page3.html
ChronosZ - it appears that the official fix will be in place soon, as Ram Guy said on the official forum. The noise is indeed annoying, but the H50 I have is making the same noise and buzzing like an old transformer on top of that, at least the H60/80/100 problem can be addressed but not this
