Can I replace the fan on my retail HSF?

I'm looking to cool down my oc'ed 2500+ chip and also get the noise level down as well. Could I just replace the fan, and if so what size is it? I don't think its 80mm.

If not, I'm thinking of replacing it with a Zalman AlCu, thoughts?

I'd replace the whole thing. Heat sink and fan. I would highly recommend the Zalman AlCu. It's great. Is your 2500+ unlocked?
