Raff,

 I found this site, looks like the VSA-100 takes a 40mm:

Try a Titan CUV2AB. Nice copper look and very strong cooling ... but rather loud.

Hi Raff,

  Thanks for the recommendation, but I really don't want to get that involved and have to take off the heat sink too.  I just want to replace the fan.  Does anyone know what size it is, 40mm, 50mm?  I've found a bunch on Ebay as well as newegg (I'm in the states).  Any other ideas?

Hi there,

   Glad I found this site.  Much better than other 3dfx sites out there.  Hats off to the owners.  I just recently purchased a Voodoo 4 4500 PCI.  Guy I bought it from shipped it in a flat bubble mailer!  It looks like it made it ok though, nothing bent as far as I can tell.  Thing was dusty too, had to clean it up.  Anywho, fired it up and everything looks ok.  Fan doesn't sound healthy and I'd like to replace soon.  Anyone know where I can buy a replacement that would fit the VSA-100?
