I've had my 1000/500/600/+4/+4 Pi hit 85C before, at which point the overclocks were automatically disabled. Normally it ticks over at about 65C (average 30%-35% CPU load at the main menu in Amber, no h264 block enabled). Not sure what caused the temperature to ramp so high, it wasn't playing any video at the time so those blocks shouldn't have been active but it may have been due to the ARM core being maxed out at 100% for a long-ish period.

Edit: In Amber, on the TV Show -> Recently Added list (in List view), with the highlight on a TV show where the Plot is sufficiently long enough to cause vertical scrolling, and the CPU is pegged at about 70%, and the temp has so far peaked at 80C...
