The Koolance CTR-CD10BK 5.25" Pump & Fan Speed Controller is a speed controller and temperature monitoring unit for 12 Volt pumps and fans that mounts in a standard 5.25" drive bay. It includes all features found in Koolance's top-end cooling systems, with a newly revised controller circuit for operation with a Koolance PMP-400 or PMP-450 pump.
The CTR-CD10 has two 3-pin fan outputs. To connect more than two fans, simply add them together with a wiring harness. The pump output is also 3-pin, requiring a 4-pin adapter if using the Koolance PMP-450 pump.
