Probably not. The PSU is a switcher that has the temperature control integrated and that controls the PSU PWM which is powered by AC. Here's a thread about all of that with representative schematics.

There's nothing to prevent you from using some of the temperature sensing stuff there to close a relay to call for cool for bang-bang control. You probably can find an electronic thermostat on Amazon or Alibaba that would do the temperature sensing and output a control signal or just make your own. Lots of help here if you want to go that route.

The relay output on some of these says 20A at 14V. That should do it.
