I am about to order a new heatsink and fan (Vantec Iceberq) for my Rad 9700 Pro - the original ATI one is slowly packing up.

A couple of questions hopefully someone will know the answers to-

How loud is this fan and can it be 7v modded safely, bearing in mind its gotta cool an (unclocked) Radeon 9700 Pro. I'm not too concerned that the LED's wont work or be as bright. The card is in a Shuttle SB61G2 so not the best airflow in the world!
