Alphacool “Eisflügel”: The flow indicator with added value! Water cooling in a computer always serves as a visual upgrade. Neatly arranged hosing or HardTubes make for an impressive sight. With the Alphacool “Eisflügel”, you can add in an extra eye-catcher. The silent revolution of the fan wheel will always show the direction of the flow. The combination of acetal and plexiglass is a winning combination which fits seamlessly into any system. Besides the two G1/4" screw threads necessary for the water flow, Alphacool “Eisflügel” also has another screw thread on the upper side which can be used for many purposes: illumination, fill port, drain port, or as an angled piece - functionality is still guaranteed even if the upper thread is used as an outlet. The fan with six blades inside is also made of plexiglass and the outer sides are marked in two different colours, blue and yellow. The side with the greater contrast can be chosen depending on the colour of the fluid.
