....thought I'd ask here, maybe theres something in the automotive world that can help me out. Looking for a strap on heatsink for a cylindrical piece I'm trying to cool. The cylindrical piece is approx 2" in diameter x 4" in length.

I'm thinking about trying an oil filter collar cooler thing from the automotive world, or a slip on heat sink for tube amplifiers. Any other suggestions?
