Hard to justify cooling you poorly when you have to use the energy or money to make or buy the ice. You will be needing extra electricity to power the pump too.
The water pump will draw an average of about 0.5 to 1 amps.
I know the pump draws 2 amps, I think the pump will only run about 25% of the time.
This system will draw less electrical power than what it takes to engage the electric clutch on an A/C compressor, never mind what it takes to constantly run the engine cooling fan and the blower (up to 25 amps continuous load) and the engine power it takes to drive both the A/C compressor and alternator.
I have already established freezing the ice and using it for targeted cooling will only require a tiny fraction of the energy needed for traditional blanket cooling an entire vehicle, no matter how you cut it.

The lower cooling pad is only 1 of up to 4 cooling pads. Lower back pad is next.

How is it cooling poorly me if after 20 minutes its cold enough to be uncomfortable and at 30 minutes its cold enough to start to physically hurt?

. The original goal was nearly met with my quick and dirty proof of concept test then far exceeded by my first build.
