To read the sensor he is using a Cooler Master Aerogate 3 and the sensor plugs up right to it. And he will not be using that controller if he gets this LCD device.

My brother was thinking of getting one of these and I had some questions about the LK204-24-USB(MX421):

1. Is the 12v fan controller strong enough to control 3 x 0.52amp fans?

2. Will the 2 wire water temp sensor he already has work? Click here for sensor
