HardTubes enjoy great popularity, and Alphacool is constantly offering new products in this area. Anyone who want to see clear, clean lines in their computer can hardly go without them. The most popular HardTubes are clear and transparent. HardTubes made of brass and carbon are also catching on. Now, under its “Eis” product line, Alphacool is offering the “Eisrohr”. Its surface gives off the appearance of ice and feels like it too – somewhat rough, but still smooth. With the “Eisrohr”, you effectively change the look of your system. You can especially see its true effects after refilling the system. The water has the appearance of frosted ice. With clear HardTubes, when the system is lit by LEDs, you see the reflection of each individual LED very clearly. Not so with the “Eisrohr”. Instead, the light is diffused and you get a softer, better illumination. Notice: The “Eisrohr”, like all acrylic HardTubes, can be bent with the proper bending tools For use with Alphacool fittings only.
