OK, after sitting on my desk during the night (turned off) the multimeter said 21C, and the empeg immediately after boot 24C. I believe 21C to be closer to the truth, as it sure didn't feel like 24C in the room...

In the car, with the heat and fan on max, everything going out the central vents just above the empeg, I couldn't get it to read above 31C.
But when I pulled it from the sled, it was definately warmer to the touch (I'd say hot, but not overly or extremely) than it was last night, sitting by the computer....

Go figure.
