Wil1948:

I never pelt cooled. Mostly becuase I never found it practical to my setup.

Your approach lowering amps is one way and the simplest. It will cause a lot of heat generation and thus power loss but the other way is PWM and that my friend will require effort unless you have cash to buy a pre built module for it.

For PWM my approach would be to use a microcontroller which will sense temp and lower or raise voltage accordingly. I might build such a thing in a few days for some other application.
