Alphacool Polar bear solo water block

With the Alphacool Eisbaer Solo, Alphacool offers a compact yet powerful foundation for small cooling circuits. The core of any water cooling system is the CPU cooler, along with the combination of a reservoir and pump. The Alphacool Eisbaer Solo combines all of this into one product.

The base features a smooth-polished cooler base made of pure copper, equipped with very fine cooling fins. This choice of material and the fine fins ensure high cooling performance. Directly above the cooler base is the combination of pump and reservoir. The reservoir has the IN and OUT connections. Both connections use the standard G1/4" thread, making them compatible with all common water cooling fittings. The Eisbaer Solo is filled through the fill port, which is also located on the top of the unit.

The DC-LT Low Noise Ceramic Pump used here is successfully employed in many Alphacool products, including the very popular all-in-one CPU coolers Eisbaer and Eisbaer LT, as well as in other products like the external water cooling system Eiswand. The DC-LT operates at 2600 rpm and can be regulated between 7 and 12 V. This can be done via an optional adapter cable or a potentiometer. With a power consumption of only 4W, the DC-LT Low Noise Ceramic Pump is one of the most energy-efficient on the market. Despite this, it boasts a delivery head of 0.85 m, making it anything but weak. Many tests of the Eisbaer CPU AiO solution confirm that the pump is among the quietest available.
