My Chroma Polaris get really hot just stitting there. When turned on I play it occasionally during the session after a good while it gets quite warm where the heat sink is and the keyboard OS eventually crashes. In a hot room ( summer , lights, etc.) the crash happens sooner. Usually no sounds are lost but I can't really use it further until after it has been shut off and has cooled down.

Any ideas as to what is going on? Improvements or repairs to be made to stop this? Similar experiences? Or does everyone else's keyboards work fine in this regard?

I've got to be able to play it in a warm if not hot room and depend on it being functional to be of any use. One would think that originally the keyboard would have been built to be robust, but man that heat-sink looks like it was designed to dissipate a lot of heat!
