I'll bet it's good enough, at least to get started.

Mine is just barely warm.  I have a large heat sink, but it doesn't have much 
in the way of fins.

If you have a large chunk of 1/8 in aluminum, that might be worth a try.  Say 
3x the area of the bottom.

What's your ambient?

You can get slightly better cooling if you turn it on its side/end, or lift 
the fins off the surface with a couple of spacers so the air can get in there 
better.
