Alphacool Eisbaer Pro HPE Aurora 360 CPU AIO (13074)

The Alphacool Eisbaer Pro HPE Aurora 360 CPU AIO is a pre-filled AIO liquid cooler with a 360 mm radiator. It mounts on AMD AM4, AM5, TR4, sTR5 and SP3 and on Intel LGA 1700, 1851, 2066 and 3647, among the sockets listed below. It features the NexXxos HPE Performance all-copper radiator, which Alphacool calls extremely powerful, equipped with three high-throughput Aurora Rise 120mm fans. Thanks to the quick-release fastener the loop can be expanded with additional components.

Fit

For compatibility with the sockets above, the box holds one mounting set for AMD and one for Intel. LGA 4189, LGA 4677 and LGA 4710 need a bracket that is not in the box. For LGA 4677 that is the XPX Pro/Eisbaer Pro LGA 4677 Mounting Bracket (article no. 13764). Alphacool's manual shows brackets for both LGA 3647 versions, SQUARE & NARROW.

Thermal compound is in the box. The manual has you clean the old paste off the CPU, apply a pea-sized blob and spread it evenly with a plastic strip into a thin layer. Tighten the nuts and screws hand-tight only, without tools. The manual adds that the radiator usually goes in the top or the front of the case.

Custom loop parts in an AIO

All of the components used come from the classic DIY water cooling range. For the most part they are also used in Alphacool's enterprise products for servers. Alphacool describes the cooler as a high performance all-in-one water cooling system. In its words it is as easy to install as an AIO, but offers the performance of a pre-assembled and pre-filled custom loop.

New HPE radiator

The NexXxos ST30 HPE Radiator uses the same materials as previous NexXxos models but, as Alphacool puts it, takes it a step further technically. Due to the condensed internal structure, the number of water channels and copper fins could be increased. Thus a larger volume of water is in direct contact with the cooling fins, and Alphacool calls the heat transfer enormously improved. The higher number of fin rows and their shortening also makes much more efficient use of the cooling surface, it says.

Alphacool's own comparison tests with the conventional NexXxos radiator have shown that a performance increase of 4.5K is possible when using the HPE radiator, it reports. At higher ambient temperatures and higher fan speeds, Alphacool says the performance gap with the normal NexXxoS radiators even increases progressively. It speaks of the gap reaching a possible performance increase of up to 6K.

Cooler & pump

On the respective processors the cold plate bottom covers the entire surface. Its fine cooling fins are distributed over an area of around 55 x 42 mm, which Alphacool says exceeds the core areas of all known processors. That way all hotspots of a CPU are directly covered and cooled, which Alphacool calls optimized cooling. In total there are 58 cooling fins on the base of the cooler, each 0.4 mm thick, with what Alphacool calls an optimal distance of 0.4 mm between them. The bottom is only 3 mm thick, which allows an accelerated transfer: the heat can reach the water and be dissipated as quickly as possible.

The cooler uses the very compact and small DC-LT 2 pump. Alphacool says it provides enough power to add another component to the circuit, such as a GPU water cooler or another radiator.

Fan

The Alphacool Rise Aurora fan offers a wide control range as well as what Alphacool calls superior Digital aRGB LED lighting. The individually controllable 5V aRGB LEDs, paired with the fan's special design, create unique effects, it says. Via the 4-pin PWM connector the fan can be controlled from 0 to 2500 rpm. Additionally it offers a Zero control, which allows the fan to be regulated down to 0 RPM. It then starts at approximately 350 RPM. Alphacool says that at 800 rpm the fan is nearly silent but still offers good airflow (118.9 m³/h) paired with high static pressure (3.17 mm/H₂O).

DIY connections and ES hoses

The hose connections are from the normal DIY segment and therefore use a G1/4 thread. Thus it is very easy to replace them. Like the connectors, the black TPV hose comes from the Alphacool ES series, which is primarily installed in servers and workstations. The hose does not contain any plasticizers and, unlike classic PVC hoses, does not deform at high temperatures. The quick connector is not made of heavy brass but of nylon, which Alphacool calls extremely light, durable and robust. Alphacool adds that the quick disconnect is compatible with many other models in its product line.

Full Digital aRGB illumination

The cooler pump assembly and the fans are fully equipped with Digital RGB LEDs, also known as addressable RGB or aRGB. The illuminated pump unit and fans give a nice visual effect.

How to connect everything

The loop arrives pre-filled with its tubes pre-mounted, so it needs no fittings. It can be opened and extended at the quick-release coupling. The manual says the coupling is opened or closed with its lock, marked by a white arrow, and is not necessarily required. Further couplings are sold as item no. 17452, our HF Quick Release Connector Kit TPV. The fillport on the cooler can, of course, be used to refill the loop if necessary.

The fans connect through the included Y-adapter 4-Pin PWM to the mainboard, and the pump goes directly to a 3-pin or 4-pin header there. Extensive lighting effects can be set with the included controller or a Digital RGB controller on the motherboard, through the 3-Pin JST to 3-Pin 5V adapter. For easier control via a controller, the fans and also the pump can be connected in series as a daisy chain. This enables a neat wiring of the individual LED components.

Notes

• When you refill or expand the loop, use only clear, transparent water cooling fluids. Alphacool warns that the particles and additives in Pastel liquids can clog and permanently damage radiators, pumps, coolers and hoses, which can also void the manufacturer's warranty.
