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. >The manual recommends a heat sink with a thermal resistance of 2C/watt >or less for ambient temperatures up to 50C. 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. -- These are my opinions, not necessarily my employer's.
