I have a Pi3B+ that i thought was running a tad hot at 56.7 C. with heatsinks...within spec but too warm for my liking..
This clam-shell heat-sink seemed worth investigating...

Arrived today and seems very well constructed.
I have assembled it and monitored the Pi for several hours...37.6 C consistent !!! same usage as previous measurements..wow that's such an improvement.. (I have the passive unit without fans....)
