Description

With the Eisbaer Alphacool fundamentally revolutionizes the AIO cooler market. If classic AIO CPU coolers are disposable products that are neither expandable nor refillable, the Alphacool Eisbaer has a modular design and can be extended, converted or refilled at any time. This means that the Polar Bear is not simply an AIO but is based entirely on classic water cooling components. This means it is quieter and more powerful than the average AIO solution.

The components in detail:

radiator
Alphacool relies on a radiator made of solid copper. The basis of the radiator is the popular Alphacool NexXxoS series which is extremely popular worldwide. The pure copper construction increases the cooling capacity enormously compared to the usual aluminium radiators of classical AIOs. The low fin density provides enormous cooling performance for low speed fans. This means that the power of the polar bears decreases much more slowly when the fans are turned down than with radiators with a high fin density.

tubes
The flexible PVC hoses facilitate the installation of the polar bears. This makes it easier to install the hoses and bring them into the correct position. To prevent them from buckling and thus stop the flow of water, kink protection springs are fitted on both hoses. The size 11/8mm also comes from the normal water cooling range and is a common size here besides 13/10 and 16/10.

quick-release fasteners
The Polar Bear has been designed directly for extensibility. Therefore you will find a quick-release fastener on one of the hoses. This quick release is compatible with the Alphacool HF quick release fasteners, which makes it easy to add a radiator with a graphics card cooler to the circuit.
Furthermore, the Eisbaer is compatible to the upcoming Alphacool GPX-Pro graphics cards AIO which will use identical quick-release fasteners.

blower
The Eiswind fans are specially designed for radiators and generate a high static pressure to push cool air between the fins. Both fans can be controlled via PWM over an enormous range of 550 to 1700 rpm. A PWM Y-Adapter is included with the Eisbaer, so both fans can be controlled via a PWM connector on their mainboard or a separate fan controller.

outlets
All connections are based on the classic G1/4 inch thread, the standard thread for water cooling. Therefore, all connections can be exchanged for others at any time if desired. This also means that they can later use thicker hoses or even hard tubes to make their system more individual.

All these features make the Eisbaer cooler something very special. The upgraded optics through the illuminated logo and the illuminated compensation tank in which the pump is also located, make the interior of every PC shine in new splendour. The soft-touch surface of the pump housing is another optical highlight.
With the Polar Bear you get an all around perfect product that is not only extremely powerful but can also work very quietly.

pumps
The basis of the pump is the Alphacool DC-LT Ceramic Ultra Low Noise which is also available separately. The pump runs extremely quietly and can be regulated from 7 to 12V. Control via the mainboard is also possible. Who operates the polar bears alone, will have hardly a loss of performance on 7V as various test results can testify. The insulated pump housing further perfects the noise development and also ensures that vibrations are almost completely absorbed.
The bright and smooth polished copper base of the cooler also ensures optimum heat absorption and can pass this on to the water quickly and efficiently via the fine cross slot structure of the cooler.

CPU coolers

Computer cooling is required to remove the waste heat produced by computer components, to keep components within their safe operating temperature limits. Various cooling methods help to improve processor performance or reduce the noise of cooling fans.

Cooler properties

i

Cooler properties

A cooler is used for heat dissipation, which usually results in a reduction in temperature. A heat sink absorbs the heat, the cooling medium (usually air or water) ensures that the heat is dissipated.

Watercooled

Water cooling is a method of heat removal from components and industrial equipment. As opposed to air cooling, water is used as the heat conductor.

CPU socket
i

CPU socket

A CPU socket or CPU slot is a mechanical component that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the CPU to be replaced without soldering.
Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with a large number of pins, either zero-insertion force (ZIF) sockets or land grid array (LGA) sockets are used instead. These designs apply a compression force once either a handle (for ZIF type) or a surface plate (LGA type) is put into place. This provides superior mechanical retention while avoiding the risk of bending pins when inserting the chip into the socket.

Voltage

The voltage between two points is a short name for the electrical force that would drive an electric current between those points. Specifically, voltage is equal to energy per unit charge. In the case of static electric fields, the voltage between two points is equal to the electrical potential difference between those points. In the more general case with electric and magnetic fields that vary with time, the terms are no longer synonymous.

Fan Properties

Fan Properties

A computer fan is any fan inside, or attached to, a computer case used for cooling purposes, and may refer to fans that draw cooler air into the case from the outside, expel warm air from inside, or move air across a heatsink to cool a particular component. The use of fans to cool a computer is an example of active cooling.

Air flow

Air flow

The volumetric flow rate in fluid dynamics and hydrometry, (also known as volume flow rate or rate of fluid flow) is the volume of fluid which passes through a given surface per unit time (for example cubic meters per second [m3/s] in SI units, or cubic feet per second [cu ft/s]). It is usually represented by the symbol Q.

106 m3/h
Static pressure
i

Static pressure

The hydrostatic pressure exerts a force on each surface in contact with the fluid that is proportional to the size of the surface - the larger the surface, the greater the force acting on it. This form of pressure is therefore a special form of elastic stress that is characteristic of ideal liquids and gases.

Manual

A user guide or user's guide, also commonly known as a manual, is a technical communication document intended to give assistance to people using a particular system.[1] It is usually written by a technical writer, although user guides are written by programmers, product or project managers, or other technical staff, particularly in smaller companies.

User guides are most commonly associated with electronic goods, computer hardware and software.

Thermal grease
i

Thermal grease

Thermal grease (also called thermal gel, thermal compound, thermal paste, heat paste, heat sink paste, heat transfer compound, heat transfer paste (HTP) or heat sink compound) is a fluid substance, originally with properties akin to grease, which increases the thermal conductivity of a thermal interface by filling microscopic air-gaps present due to the imperfectly flat and smooth surfaces of the components; the compound has far greater thermal conductivity than air (but far less than metal). In electronics, it is often used to aid a component's thermal dissipation via a heat sink.

Eisbear 280

Im Grossen und ganzen ist diese AIO WAKÜ ganz in Ordnung. Ich habe mich jedoch an dem Pumpengeräusch doch gestört und dann kurzerhand ein eigenes System zusammengestellt.

Kühlleistung ist sehr gut. Jedoch haben bei meiner die Lüfter schon nach relativ kurzer Zeit begonnen zu klappern. Auch die Pumpe gibt gelegentlich ratternde Geräusche von sich.
