First off, I think it's a waste to get one, but if the stock cooler is too loud then so be it.
With that being said, the H7 is really top quality, at a nice price. The Thermaltkae isn't too shabby, but it's smaller as well. With that H7's size, it allows it to grab more heat and cool better. I have uing the FrioSilent, but looking at it, and reading up on it, I wouldn't go for it, when the H7 isn't that much more expensive.
