I do not believe you should put your cat in warm water at all. For one reason, it would only increase the humidity.
Another suggestion is to wipe down your cat's paws with a cold/cool wash cloth or even an ice cube. Surround him with ice packs
How hot is it inside? Although I had ac where I use to live, the temp inside rarely was below 82. I put lots of fans on the floor (which is where my cat would lay). When I lost power for several days, I and Ritz stayed with my sister.
Tile/wood flooring I generally cooler than carpet. I'd try to get your cat to stay in these rooms.
