EDIT: 3DFXCool Alpha P3125 slot 1 heatsink I believe called. Back in the day I had a pentium 2/3 slot 1 massive black aluminum heatsink with a copper core. Had a silver colored steel shroud and dual fans.. made by Alpha. That all I remember.. i dont remember what the name was but atleast know the manufacture. Was tops back then and heavy and loud. Been looking for years. I have like 1 pic of it installed and I'll upload it later on. If ya think you have it tucked away please look for it and name your price!
