Design and Installation

The waterblock/pump assembly for the Eisbaer coolers contains a window to check on your coolant, and the hoses feature anti-kink springs at both ends.

The top of the assembly has a refill port and a logo that is illuminated with a blue glow during operation.

The pump is Alphacool's DC-LT Ceramic Ultra Low Noise model, which can be operated at both 12v and 7v by adjusting the motherboard header setting (if available). I tested this at the standard 12v from my motherboard's primary system fan header.

The base of the block is copper, with a flat, smooth surface. Mounting hardware for both AMD and Intel is included in the box, and Alphacool is now offering AM4 mounting kits for AMD Ryzen processors.

Next we have a look at the radiators, which are of a premium all-copper construction and feel very substantial:

Both radiators have the same thickness, and I was curious to see whether a 280 mm or 360 mm solution would be more effective (though much of this has to do with the fans, of course). Here we see that Alphacool has preinstalled anti-kink hoses on the radiator side, as well.

Next we have a look at the included fans, the Eiswind-12 and Eiswind-14:

The Eiswind-12 fans are rated for PWM operation from 550 – 1700 RPM, while the larger Eiswind-14 fans are non-PWM, and spin at a fixed 1100 RPM.

Installation begins for both coolers in the same way, with the proper mounting bracket (both AMD and Intel brackets are included).

The completed bracket installation also involves bolts, nuts, washers, and springs; though this was easy enough after glancing at the instruction book for the proper order.

I installed both coolers onto my LGA 2011 test system, so I did not require a bottom bracket (also included). As with most liquid CPU coolers, the water block/pump assembly does not interfere with surrounding memory or other components.

Next we will take a look at the performance of both Eisbaer coolers on the test bench.
