Pump

The P400 housing is made of a hard plastic and sets on a removable pedestal, which comes with mounting screws. Because of the way it mounts to the liquid tank you can turn it 90 degrees and mount it.


The back of the P400 provides cooling vents for the motor housed inside. Thermaltake doesn't mention if the motor is brush-less. The rated voltage is DC 12 V, 900 mA max. current with a sleeved 4-pin connector.


The best design of the P400 or what I like the best is how easy it is to open and clean. The outside housing cover is held on with plastic clips and after removing the intake fitting the cover is easily removed. We can see the heart of the P400 after only removing two screws and twisting the top of the pump cover free of the molded slide lock, which we can see in the picture below in the red square.


The P400 runs on ceramic bearings and has a Lifetime rating of 70,000 hours (MTBF) which is a good 20,000 hours higher than most pumps in its class. The noise level is rated at 16 dBA and a blue LED is on the top backside of the P400. At 16 dBA the P400 is hardly audible.
