2400MP Projector cooling

I was wondering if anyone knew if it was possible to extend the 90 second cooldown period following shut-down of the 2400MP projector. The projector shell still seems too hot to place in the carry case even after 6-7 minutes.

I conduct training for organisations and sometimes they are waiting to close-up their business when I'm finished, leaving little or no time to wait for a longer cooldown of the projector.

Thank you in advance.
