Most good heatsinks have the ability to accept 80mm and 92mm fans out of the box. It's only the retail (IMO crappy) heatsinks that you have to worry about the hair dryer fans. I'm sure its MUCH better than what you had, but if you want quiet, you should have gotten a 60mm to 92mm adapter and a Panaflo. Then that system would be near dead silent. It looks good though, I'm sure it's a lot less annoying now

PS - don't anyone jump down my throat about calling retail heatsinks crap. I just either a) overclock the hell out of my systems, or b) want them as quiet as possible, so the retail heatsinks are a no no for me.
