when choosing a HSF, you have to take alot of different things to look at. how much to spend, how cool do you want it, how loud a fan you can stand...etc. my suggestion for the best bang for your buck is the svc goldengate w/ 40 cfm fan found here:
linky. mind you, that fan is one loud lil sucker tho so if noise is not your concern, that copper unit does a great job and for that price? good lawd. if not, the thermaltakes do the job well and aren't as loud. so you really have to sit back and put all those factors in when you're choosing your HSF. gl.
