I just sold 30# of aluminum heatsink approx 8"
wide x 4" high x 5' long for
$40.00. 9 other identical pieces were scrapped out for about $15.00 each. My
understanding is that they were in the $100.00 + catagory when new.
And that sounds like it was for stock extrusions. If you add all sorts
of machining so the heatsink actually touches the processor, you can
add a bunch more on to the price.
Fans are cheap and effective.
And the last place *anyone* wants to go is liquid cooling.
