[Coco] CoCo 3 Voltage Regulator heat sink

[Rick Taylor]

I had found a heat sink in a box - it's something I pulled out of an old
switching power supply, I think, maybe 3.5 inches square aluminum with fins.
I have it vertically mounted, seems to be adequate, but barely.
Incidentally, while putting the thing vertical, I applied a bit too much
torque and crunched the D880. I went to Jameco (with the mobo) and picked up
these at their will call counter, with a little help from them figuring out
what to use

I'm running it off a 200W AT style power supply. It's getting fairly toasty
but it's been running for about an hour and nothing's caught on fire yet
:-)

You can hold on to it for about three seconds before you go "wow! that's
hot!" and let go. I'm not particularly good with electronics. What would be
a better replacement that might run cooler?
