splitters and fans can be found at www.newegg.com
i believe it's a 68mm, maybe its 60 mm are the small fans your talking about, yes you could put one on, but you'd have to find one on newegg with some way to attach it,an 80mm fan wold work too if you couldn't find the small ones, or you could just mod your case and put a fan in front of the heatsinks. i think under one of those heatsinks is hte northbridge chipset but i'm not sure, cooling them probably isn't too important though.
