## Long description

The Koolance EX2-755 12 cm Black is a liquid cooling kit engineered for high-capacity thermal management in desktop computer systems. This ambient liquid cooling system includes a dual 120 mm fan aluminium radiator, an adjustable-speed pump and reservoir, and multiple control options for temperature-based automation and manual adjustment. The unit is supplied in a black finish and requires user-supplied tubing, fittings and coolant to connect to cold plates or components.
Advantages
The EX2-755 delivers up to 590 W of cooling capacity with a 25°C liquid-to-ambient delta at a flow rate of 4 LPM, making it suitable for demanding CPUs and multi-component cooling loops. Fan speeds and pump speed are adjustable with automatic temperature-based control or manual selection across ten levels, while three included temperature sensors and a configurable relay provide advanced monitoring and alarm capabilities. The unit supports multiple power input options and uses standard G 1/4 BSPP threads for fittings, simplifying installation with commonly available water-cooling parts.
Suitable for
High-performance desktop CPUs and overclocked systems
Custom liquid cooling loops for multi-component systems
Workstations and servers requiring consistent thermal headroom
PC builds where a 120 mm fan radiator and black aesthetic are desired

How to use
Install the radiator and fans in your case or external mounting location, and attach tubing and fittings to the G 1/4 BSPP ports on the unit. Fill the loop with compatible coolant and purge air by running the pump at a low speed until flow is stable. Connect power either to the computer Molex plug (12 V DC) or use the separate AC adapter if available. Configure fan and pump speed using the automatic temperature-based controls or select manual levels as needed. Position the temperature sensors near the components you want to monitor and set the audio alarm thresholds and relay behavior according to system requirements.
Usage recommendations
Use coolant and tubing materials that are compatible with aluminium radiators to prevent corrosion; follow manufacturer guidelines for coolant concentration and change intervals. When assembling the loop, ensure all fittings are tightened to specification and perform leak testing before powering other system components. For best thermal performance, maintain a steady flow rate near 4 LPM and allow the automatic controls to adjust fan and pump speeds based on measured temperatures.
