You might could get someone at Fry's to do it for you, but they'd charge ya $10 or $15. I say might because they'll test mobo/cpus you buy there for a fee, but... you already own this CPU. Anyhow, I'd just go ahead and get the new CPU fan. Even if your CPU is broken and needs to be replaced, a big, badass CPU fan is always worth the money.

What is it they say about silence being golden?
