Another thing we had to do while out on tour, outside, sheds in 100+ deg heat... Also with the digico consoles and their power supplies...

We hung open bags of dry ice in front of the vents and put a fan, forcing some of the now cold air in the humid hot environment into the machine. Never shut down after that...
We just asked the dry ice people for a bag. It was cloth mesh style bag. Just filled her up, and hung in front. Worked great...

Just a thought.

I know in Singapore, without the dry ice, i was overheating and shutting down 4 catHD as well as 4 hippos.
