Pump - 5 Liters Of Water A Minute

To keep water flowing through the cooling system at a decent clip, you need a pump. In general, any aquarium pump will do, as long as its flow rate and electrical connections are adequate. We used a centrifugal pump with a maximum flow rate of 300 liters per hour (according to the manufacturer), which is actually more than sufficient. In reality, the flow rate ends up being lower, due to narrow hoses and adapter interference. However, this pump is more than sufficient to cool an AMD Athlon processor at a loss rate of up to 85 percent, depending on the version and clock speed. You could use the same set-up to cool an Intel Pentium III or an AMD K6-2 (Socket 7) effectively. The following pictures show the pump and its inlets from different angles. In addition, we've prepared a table with the pump specs.

This small aquarium pump suffices to keep the water circulating in a cooling circuit.

The inlet and the outlet have been fitted with hose adapters.

The adapters reduce the inlet diameter, which allow small hoses to be attached. The sealing rings prevent leakage.

The pump and adapters are ready to be hooked up.
