Alphacool Eisblock XPX 1U CPU Water Block, Black

The Alphacool Eisblock XPX 1U is a CPU water block for 1U server racks, for AMD AM3, AM3+, AM4 and AM5 and for Intel LGA 1150, 1151, 1200, 1700, 1851, 2011, 2011-3 and 2066. Five of its seven G1/4 connections are on the side, so the tubes can leave sideways and the block with its fittings stays inside the height of a 1U server case.

Properties

• Intel sockets: LGA 1150, 1151, 1200, 1700, 1851, 2011, 2011-3, 2066
• AMD sockets: AM3, AM3+, AM4, AM5
• Cold plate: Nickel-plated copper, 81 fins of 0.2 mm
• Top: Acetal, black
• Ports: 7 x G1/4 (3 x IN, 4 x OUT)
• Size: 65 x 65 x 25.5 mm

Fit

Alphacool says mounting material for all mainstream sockets from AMD and Intel is included, and that the Eisblock is compatible with many sockets from Intel and AMD, as well as for all 1U cases. Its current compatibility list is the one in the Properties above, and the mounting steps in its manual are for LGA 2066, LGA 1700/1851, LGA 115x, LGA 1200 and AM4 / AM5. The manual shows one pair of brackets for those Intel sockets and one pair for AM4 / AM5, a backplate, and a set of four screws for each group.

Alphacool does not include the mounting materials for some Intel Xeon sockets and the AMD Threadripper. For these oversized processors it recommends its Eisblock XPX Pro series, which offers adapted mounting material and an enlarged cooling surface. We stock that as the Eisblock XPX Pro 1U.

On the Intel sockets that use it, the backplate is attached to the mainboard from behind. Then the mounting frame and the mounting screws, which can be pre-assembled separately, are attached directly on the CPU block, and block and frame are screwed to the backplate. The manual has you tighten the screws hand-tight only, without tools. It also notes that the rubber and screw caps it shows are not included with this block.

What the loop needs

The block has seven G1/4 threads: 3 x IN and 4 x OUT, with 2 x IN and 3 x OUT mounted on the side. One IN and one OUT take the compression fittings for your tube size, which are not in the box. According to the manual, all IN and OUT can be combined with each other. Its accessories page lists five G1/4 screw plugs and a tool for this block, to close the connections you leave unused.

Straight fittings up to a size of 13/10 mm can be connected at the side, and Alphacool calls its TPV connectors, developed for the Enterprise Solutions series, ideal there. Larger fittings can be used at the side only in specific circumstances, with angled adapters. On top, all connections up to a size of 16 mm outside diameter can be used, no matter whether for soft tube or HardTubes. The manual puts the limit for a connection at a diameter of 18 mm. There is no lighting to connect. To run, the block needs a pump and a radiator in the same loop.
