The Alphacool Eisball expansion tank with integrated pump top has a unique design. The unprecedented spherical shape opens up countless new possibilities for you, especially in the modding area. From static, monochrome lighting to the R2D2 mod: there are really no limits to creativity. Another special feature of this version: the pump is already pre-installed. Alphacool uses the tried and tested D5 VPP655 ice pump. Versatile mounting options Don't be limited to a single mounting option! Thanks to the adhesive mat and 2 different mounting plates included in delivery, many different mounting ideas can be realized: whether on the radiator, the fan slots, or a 2.5" SSD space. Alternatively, you can of course also use the tried and tested universal Alphacool pump mounting. In conjunction with the VPP655, the Alphacool Eisball can even be operated upside down. However, only and exclusively with the Alphacool VPP655 pump. Standard Laing D5 pumps cannot be operated upside down due to the spherical bearing. Note: The ice ball cannot be operated upside down with the VPP655 pump!
