Can someone remind what this thread is actually about? I've just read it twice and by the time I get to the end I've lost the plot again.

PS Aircon in the centres is definitely to support the equipment. (Alright I'll admit that's not the only reason but it's the mandatory one) There are contingency plans to mitigate against failure and none points to cooling the fat b@stard in front of the screens. Normal ops, air is pumped into the consoles at 16⁰C to keep the computers cool. Consoles don't work above 43⁰C and they reach that about 20 minutes after the aircon fails if alternate cooling not available (meaning removing cowls and bringing in fans).
