Teamviewer overheating hosts' computers

A coworker and I are both using TeamViewer to host working sessions on our MacBook Pros (mine 15", 2016, retina) and his (2011, 13" MBP).  Whenever a client logs in to watch, our host laptops immediately begin overheating.  It gets so hot you could fry an egg -- too hot to keep in our laps!  The fan goes to max and is incredibly loud.  Heat builds up faster than the fan can dissipate it -- even at max.  We have no other programs running.  I checked Activity Monitor, and TeamViewer is hogging over 80% of the CPU cycles and all the network traffic.  This only started happening to both of us when we upgraded to TV version 13 last week.  Anybody have any suggestions?  We can't use TeamViewer anymore if it's going to fry our MacBook Pros!
