mini fridge upgrade

Hello everyone, I found a Thermoelectric mini fridge at the dump a couple weeks ago and so far I have been disappointed with how cold it gets so I figured I would replace the peltier chip with a higher wattage one, the original ran on only 12v with 60watts but the new one uses 16v and 192 watts, so unfortunately when I switched the chips the fridge makes a clicking noise presumably from drawing to much current. the questions I have are, how can I build or cheaply obtain a variable (it would be nice to control power) 16v 12amp power supply or modify the existing board to output more power, would it pose a problem to run the fridge with no load attached to the previous 12v supply, and is it necessary to replace the fans with higher power ones? any other advise would be much appreciated, thanks in advance :)
