I have about 890 high heat dissipation finned aluminum heatsinks for sale. These heatsinks were custom made for a power supply I was developing when I had to abandon the design. These heatsinks are 5.6 inches long and 1.4 inches wide and 1.75 inches tall. I would like to sell these as a lot. Two years ago I paid $8.50 each + a $1200 one time tooling charge for them. They are still in original package as received. I have a drawing and photo available.
Let me know if you or anyone you know might be interested.
