Heatsinks... no such thing as too much?????
 
Well maybe there is for an Aleph 3.

I have obtained a large number of 15" long 1/4" x 2" extruded aluminum angle pieces. My intention is to mill back one of the legs to ~1-1/4" and mount these on a couple of copper bars to fabricate a large heatsink. The overall dimensions would be 18" x 20" and wind up with 18 legs, each 1/4" x 2". Each of the two sinks would weigh about 20 lbs.

What say you?

One and only?

You can't really go wrong with big lumps of metal! :)

The only issue I can see with heatsinks in the diy arena is cost...

Hey, if you need more space, I'll lighten the weight. Send a couple to me.

You`re right, I can`t. Therefore I sold many of them:

Still have a nice bunch though:)
No idea when IŽll have the time to use them, maybe when I`m old and deaf (but when I`m not blind too, at least I have a nice eyecatcher to look at).;)
