Step 1: Materials
CPU liquid cooler
PVC Water Hose Pipe
Small water pump
Step 2: Production
Remove the radiator from the cpu liquid cooler and attach the pvc water pipe to it using aquarium silicone, the water must travel thru the radiator. We cannot use the water pump from this model of liquid cooler because we cannot attach the hose to it. On other cpu liquid collers the water pump can be used because they have hose connectors.
Attach the water pump to the hose
Cut holes in the icechest lid for the cpu liquid cooler and the air inlet and outlet
.Use screws to attach the pieces and insulating material as you can see in the pictures
The cpu cooler fan need 12v, the battery can deliver only 5v, it is ok for the 6v water pump but a DC-DC booster must be added to raise the current to 12v for the fan
Step 3: Result
Connect the battery and turn it on.
Use cold water and ice to make it more efficient
