Anybody checked temps on the Obi chips? I cracked mine open as soon as I got it, and the 12/3.3 Volt DC/DC chip is the hottest I have ever seen in any ATA I've looked at! By far...
My little infrared thermometer was saying 70 deg C, PCB by itself, wide open!!! And the chip itself must be quite a bit warmer as the "beam" of my themometer is way too wide to cover the chip alone.
Anyrate: I already cut a piece of 486 CPU heatsink and epoxied it in place. Did the same to the main CPU as well, while at it. Also cut big openings in the SIDES of the plastic case, and covered with mosquito screening...
Oh yea: also soldered a Anderson pigtail for best "lead acid"-style 12 Volt DC uninterruptible power supply. (I like my telephones to be direct "lead-acid" power, NOT AC...)
