I contacted a a few places around here regarding rebuild, and thay just looked at me with a big question mark!!!! Try P/N 19114 on http://www.perma-cool.com/Catalog/Cat_page16.html It is sold by many distrubutors. Jegs.com is one of them. I am running P/N 19008 in my ATX and have no complains. hope thuis hekps
