I'm using my 15 inch rmbp as a desktop replacement, power the apple TB display, and the LG 34 inch display. I noticed my laptop getting pretty warm so finally installed istat and see that temps from doing normal operations (browsing, itunes, no flash, document editing), temps range from 51 celsius to 65 celsius. If i unplug it and just use it as a laptop, temps drop to ~35 celsius. When connected to screens, it's on a 12 south hirise, lid closed, for better air circulation. I'm not too worried at 60 celsius because from what I've read, it's designed to run as hot as 100 celsius when under heavy load. I'm just concerned that the temps go up almost 30 degrees celsius when it's plugged into the displays with its lid closed. Its lid open while connected to displays doesn't help, it actually gets even warmer (gfx card under heavier load i suppose) Normal? Okay for the long term? Should i just consider a refurb mac pro?
