What model Dell is that from? I have a 350 watt peltier I am building into a water chiller for the laser cutter and need a monster heatsink to remove heat

I have some of those very same heat sinks, mine came from a Optiplex 620 and Optiplex 760.
Hope that helps

Thanks! Found one on ebay cheap. Need to measure the peltier and see if it is a big enough contact patch.

Let me know what they go for on ebay, I could send you one FREE!! just pay shipping.
OR let me know what size you're looking for I'll dig into my grab bag of stuff .
At the FD we MUST trash older computers , being in their IT dept  8) I get first pick. I think I have about 6 of these!

Think it was $15 shipped... but my Peltier is huge... 62mm square! The one I was looking at had a ~ 57mm square contact patch... so back to the drawing board. I may go with a water cooled unit but they are not cheap!

That's not huge! IF google is correct, 62mm is only 2.5 inches. Let me dig into my stash and see what I've got.

I know for sure my wife would love to have some of these out of the way  ::).
They don't weigh much at all, I'm certain the fans that keep them cool are 3x3inches.

the aluminum fin area is huge, the copper heat spreader is smaller!
