I was in the same boat as you recently. Used to get headaches from the high pitched pump whine. I modified my MCP355 (converted it to 3pin) and connected it to a fan controller to be able to control the pump speed. IIRC that pump runs full bore at around 4200-4400RPM, I was running it at ~3000RPM. That helped a little, but the best advice has already been given earlier in this thread. You must decouple it from your case before you can make it silent.
