You think that they would know their stuff. But their heatsinks don’t quite do that. They get close. My 3 PRS10s are all bolted to heat sinks supplied by SRS. There are two versions of sinks that I have, a older thick ribbed type and the latest non ribbed U shaped type which I must admit looks terribly over-priced. The latest one is slightly better and keeps the measured temp at the baseplate surface to 42°C in a 25°C free air environment. The older one keeps it below 43°.
