Information about CoolIT Systems Domino ALC

[Rebella]

The choice between air and water cooling for the CPU is a matter of conscience for many users, because both systems have many advantages but also disadvantages. While good air cooling can be realized already relatively cheap, easy installation and maintenance, there are in the border area between the minimum volume and maximum performance or significant reserves. However, offer Chillers extensible and customizable, extremely powerful systems for the entire PC as well as low noise as required. The high acquisition costs and the much more complex initial installation scare many, especially something inexperienced users, however. Occasionally, some manufacturers try to combine both systems and simple, powerful cooling to liquid-based complete with radiator, pump and CPU-cooler in a closed loop create. For example, storage specialist Corsair has the " H50 "definitely reap good reviews. A similar concept CoolIT system and has wants to unite with the "Domino ALC" for some time an "all-in-one liquid cooling for the CPU, the best cooling performance, simple and maintenance-free operation and low noise background, in the offer.

The CoolIT Systems Domino ALC (Advanced Liquid Cooling) combines the three main components of a liquid cooling in one system. Basis of the design is a compact, copper CPU cooler in a 50 x 50 mm format with internal micro-structure for effective heat dissipation. The flat contact surface to the CPU is nickel plated to prevent corrosion effects. A universal standard, diagonal adjustable four-point support for the supported Intel socket is threaded, which can be replaced if necessary against the accompanying delivery AMD counterpart. Quality leaves the CPU cooling element has a very ordinary impression. Two very inflexible, about 25 cm long plastic tubes that are connected very safe with cooler and radiator, the material is transported unspecified coolant to the heat exchanger. Here, a 120-mm standard model comes with corrugated aluminum fins and very closely with some distance in the centimeter liquid-carrying capillaries used. The radiator measures about 157 x 120 x 27 mm and fits just so in the 120-mm rear fan position of most ATX cases. Was placed directly on the radiator, the control center of the cooling system in a little less impression of the quality, but still sturdy plastic housing. This was designed so that when the chassis with side window about 45 x 25 mm large backlit display can be read. In enclosures without view window, the LCD has placed there, however unfortunate. Case with additional fans or an air tunnel in the side wall may even be incompatible with Domino for cooling.

The display indicates the current operating mode, the coolant temperature and the speed of the pump. The CoolIT system offers the user three different modes of operation, differing only in the speed of the radiator fan. The minimum small, on the control box fixed 12-volt pump operates constantly at about 3,000 rpm and can not find any speed respectively noise reduction by Voltage dimming, but failed even at moderate reduction of tension, accompanied by the alarm of the CoolIT product, their service. Three operating options offers the Domino ALC, which can be switched through a button right on the side of the control unit. "Quiet" and "performance" to describe this speed spectra between about 1,100 and 2,500 rpm, which is controlled based on temperature-dependent differences in the structure control curves. During the full load test process moving minutes, the speeds in "quiet" mode with our sample 1000-1700 rpm, in "Performance" mode about 1500-2100 rpm. Depending on the workload and stress can lead to differences here, however - min quiet operation below 1,000 rpm, the system sees unfortunately not yet available. "Full" as the third option, however, describes the constant maximum speed of 120-mm fan, which is located minutes at 2,500 rpm.

From the factory, the installation of the 120-mm-type fan with four screws on the radiator in sucking position. This means that sucked in to cool the warm air inside the housing through the heat exchanger and transported to the outside. As will be seen later, is, in terms of a minimum CPU temperature, a blowing fan installation but significantly more useful. Then, however, the complete cooling system are matched in the housing so as not to generate excessive chassis and component temperatures. A general Replace the fan is unfortunately very difficult. CoolIT has been devised for fan and pump, a common power supply via a 3-pin fan connector. Already turning the fan turns due to the short cable as a real challenge. A real change is probably only can therefore be sized by hobbyist skills to the loss of warranty. The assembly concept of CoolIT Systems Domino is relatively simple. With removed the motherboard is suitable for the system back panel is selected and tightened the already prepared with thermal grease CPU cooler with the four spring nuts alternately. Now you have the motherboard along with the cooling system will be reinstated into the case. It could be to act with appropriate care, as the nearly one-pound radiator part is still unfixed and cause damage.

The attachment of the heat exchanger at the back of the case turns out to be patience. On the one hand, the place is just enormous dimensions, on the other hand, prevent the rigid tubes comfortable maneuvering. The attachment of the radiator is to reduce noise using four rubber mounts. These corresponding to thread into the holes of the housing also requires some skill and nerves of steel. A big problem is the dismantling of the heat exchanger. The rubber decoupler present themselves but very fragile and break with stretching a preference. Rapidly since the two additional copies came with are gone. A more durable solution would be but very desirable. As a suitable case for the test assembly in the closed, stagnant ATX System Case King provides us with the Silverstone TJ-09S , a spatially generously sized basis. In addition to the generous space available here is mainly the position of the power supply on the bottom crucial to a fair test conditions because of the fans of our 650-watt Lian-Li Silent Force power supply can develop there is no effect on the processor cooler. Shall elaborate the only case fan with the Scythe S-Flex 800 is a silent 120mm rear discharge model and supports the CPU cooling in the active and semi-passive test modes. Thus, the most important cornerstones of the system, which appears in the general survey as follows, first outlined:

• Intel Core i7 920 "Bloomfield" (4 x 2.66 GHz)
• Intel DX58SO "Smackover" motherboard
• 3 x 2 Gb OCZ DDR3-1066 Platinum XTC
• Asus ATI Radeon X850 XT (cooled by Zalman VF-900Cu)
• Lian Li Silent Force 650 power supply (with 140-mm-ventilation)
• Silverstone Temjin SST-TJ09S case (Case Fan: Scythe S-Flex 800)
• Samsung SpinPoint F1 HD322HJ Hard Drive
• Thermal compound: Arctic Cooling MX-2

he temperature measurement results are often quite strongly linked to the test platform used and can vary significantly depending on the configuration. You should only as a guide and gross trend, however, are not regarded as absolute. The measurement of the volume occurs in the particular operation of that cooler (the fan is powered by a passive power supply) in 40-cm intervals with a Voltcraft-320 sound level meter that the noise emitted by the known A-weighting curves in a range from 30 to 130 decibels interpreted. The overall volume of the measuring room with subjectively perceived silence is 30.4 dB (A). Above this threshold, the noise emitted from the radiator can not be resolved by the instrument. To about 35 dB (A) depending on the sensitivity of the user can rate and character of the sound to assume that the fan noise when the housing is closed, respectively not be perceived any more. 40 dB (A) of our scale, the noise can be clearly heard to very clearly, from 50 dB (A) starts the very disturbing area. Furthermore, it was generated by the fan wind speeds measured with an anemometer and indicates the maximum speed as an indicator of the volume of fluid. From this value can be obtained on the conclusions generated by the fan air flow rate. To obtain the most meaningful picture of the cooling characteristics of the subjects, we test the coolers in various CPU modes that target due to different clock speeds and operating voltages and case ventilation intensities tasks to the respective products. For example, while in "standard mode" the demands of a retail coolers are still relatively reasonable, few can top cooler can withstand the demands of "performance" mode with low active speed. Supplemented the list of "semi passive test," in which disabled the CPU fan and using only the air from the only case fan at different speeds is guaranteed.
