After about 1 minute of live-view you need 8 minutes off for the sensor to be back at the temperature it started.
I've read that the flip out liveview is far more desirable as it moves one of the largest causes of thermal noise in the camera (the LCD screen) away from backing directly onto the CMOS chip, as in the case with the fixed LCD screen DSLR's.

Whether or not this was concerted opinion or backed up with any actual tests or not I really don't know. Seems quite plausible. If that is the case I wonder what the difference in thermal noise from the LCD screen difference is between flip out and fixed position LCD screens.
