If it were my job to run around in a Barney costume and hug little kids all day, I would want nothing less than an industrial sized air conditioner.
About 20 percent cooling, and 80 percent extensive, I'd wager.
If you're not a fan of metal, then test your mettle with wood!
Just in case you worry about the adapter becoming too hot.
For those of you who might be a little bit confused, a GPU heat sink is supposed to look a little something like this. The one pictured is about as useful as a fan with no blade!
