You've gotten a lot of feed back already, but I'd suggest if your CPU's below 60C, you don't need to worry. If you have some major bucks to spend, and you want a quiet, easy to install, and eye catching cooling system, Zalman makes a great water cooling kit. The water pump is submerged in a 3 liter (!!!) tank, and is completely quiet. It can eliminate the CPU and video card fans (optional). Definitely how a "wow!" factor. http://www.zalman.co.kr/
