CoolIT ECO A.L.C. water cooling system review

As per the Domino, CoolIT's ECO ships with its own 120mm fan firmly attached to the cooler's radiator. Whereas fan speed on the Domino was controlled by a button on the unit itself which allowed you to cycle through three performance profiles, this time around the 120mm fan is controlled via a four-pin PWM header on the motherboard itself, allowing the ECO to adjust fan speed dependant upon CPU temperature up to a maximum of 1800 RPM. We're a big fan (with every pun intended) or PWM-controlled fans here, so in our book this is a definite improvement over the manual controls offered by the Domino, although of course your mileage may vary.
