A 486 fan will do fine. The 486's ran off 5v, and produced one heck load of heat compared to even a modern 3d graphics chip ( I know, I once touched a heatsink that had no fan, and was nursing my finger for a week...)
You guys might also be interested to know that there are new BETA drivers up on 3dfxgamers.com..version 1.5.01 ...look for the forum message that I put up not so long ago for the link ,cos i lost it now...
