The heat sink of a computer processor is also reminiscent of the Chill Solutions Thermoelectric Chiller. You'll attach it to a water pump instead of a probe. The pump will then circulate tank water into the chiller and back into the tank through tubing. It can also lower the temperature in aquariums up to 30 gallons in size, whether saltwater or freshwater.
How does a thermoelectric chiller work in an aquarium?
