Asus to Start Shipping Radeon R9 290 DirectCU II OC Graphics Card

Next week Asus is going to start shipping its newest graphics card from Radeon R9 series. Codenamed Radeon R9 290 DirectCU II OC, it is based on an original PCB with black-and-red design and the incorporation of an exclusive DirectCU II cooling system. Plus, the availability of ‘OC’ in the codename implies the availability of factory overclocking.



Asus Radeon R9 290 DirectCU II OC takes GCN Hawaii core with 2816 stream processors as the basis. It operates at an overclocked 1000 MHz frequency. The model is equipped with 4 GB of GDDR5 memory (512-bit bus) that runs at an effective 5400 MHz frequency. Just for a comparison, etalon adapter from AMD runs at 947 MHz/ 5000 MHz for GPU/memory correspondingly.


DirectCU II cooler consists of a heatsink, four copper nickel-plated heatpipes (two of them feature 10 mm dimensions), and two high-performance fans: one ordinary and one CoolTech. The card receives power via 6+8-pin connectors and might require not less than 600 W PSU.

New Eisblock XPX Water Units by AlphaCool

Transfer efficiency of the thermal energy flux from the CPU to the cooling liquid in the circuit depends on the water unit. The AlphaCool Company, being famous for its liquid-cooling system components, has presented a new water units series, called Eisblock XPX. They’ll take the place of the previous model, NexXxoS XP3. The series of Eisblock XPX water blocks will be released on the market featuring various colour schemes, including the mountings colour. The manufacturer has taken into account the latest trends.



In new models the heat-exchange zone microchannel structure is refined: the fin spacing is reduced to 0.2 mm, and the fins number has grown up to 81. Thus, the heat-exchange area has become larger. The brand Ramp technology is applied to the heat-exchanger, which guarantees the absence of the coolant flow vorticity and its steady passing through the microchannels zone. At the same time the hydraulic circuit has been optimized to diminish flow resistance. Eisblock XPX …

Xigmatek Manifests Specifications of Apache III

Xigmatek, a Taiwanese manufacturer of PC cooling solutions, has just promulgated the specifications of its new cooler series entitled Apache III. The series consists of two models only, which differentiate themselves by the casing's material and color. Model CD901 is housed in a silver aluminum casing, while model CD903 – in a black anodized aluminum casing. Both models have been developed specifically for CPU cooling purposes; they are able to support various platforms offered by Intel and AMD: LGA 775, 1155, 1156 (Intel), Socket AM2 and later (AMD).



Both models in Apache III series are equipped with a voluminous aluminum heatsink and 92 mm fan with half-transparent orange ribs. The fan is based on Long Life bearing and features PWM facility that allows for the adjustment of fan rotational speed. The speed span variates between 1200-2500 rpm, depending on the CPU temperature and loading. The noise level does not outreach the measures of twenty dB.
