Use the vented back of the polycarbonate housing, not the sealed waterproof one. Maybe that will keep it a little cooler. Just pop a 32G in there, a nice fresh battery...set it and forget it!
"With a single battery, you will get approximately 2.5 hours of continuous video recording time in mild and warmer temperatures*. Cold temps will reduce run times somewhat, however the camera helps to minimize this by transferring the normal heat generated during operation towards the battery"

Answer
Recording time will vary according to the resolution setting used and the card capacity. Here are the average recording storage times for an HD HERO2 camera with a 32GB SD card:
1080p (30 fps): 4h 21m
960p (30 fps): 5h 26m
720p (60 fps): 4h 21
720p (30 fps): 8h 09m
WVGA (60 fps): 8h 09m
Reduce the record times to half for a 16GB SDHC memory cards.
