HIS Radeon R9 290 IceQ X2: Graphics Card with an Offbeat Cooler

HIS has recently replenished its Radeon R9 series of graphics cards with a new model – the Radeon R9 290 IceQ X2. Based on AMD Hawaii Pro chip, this card is a combination of an ultimate efficiency and an offbeat design. The integrated GPU runs at an etalon frequency — 947 MHz. No changes have been incorporated into the frequency mode of GDDR5 memory: the 4 GB memory with 512-bus interface runs at nominal/effective 1250/5000 MHz frequency.



The major peculiarity pertained to the model is the employment of a proprietary two-slot cooler, codenamed IceQ X2. It consists of a spacious copper base (40x47.5 mm), a large aluminum heatsink, a pair of 89 mm fans, and five nickel-plated heatpipes: 2x 8 mm and 3x 6 mm. The cooler also accommodates additional heatspreaders, which dissipate heat in memory and VRM sections. Moreover, the framework boasts a dedicated stiffening plate that reduces loading on the printed circuit board.

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 …

Graphics Card Palit GTX 660 Ti JetStream Review

All graphics solutions represented in the market can be divided into three main groups: high-end cards that are destined for inveterate gamers and professionals, mainstream products for ordinary needs of average customers, and budgetary items for basic PC needs. Each of the segment is constantly replenishing with new products to satisfy the rising demands of consumers. Graphics solutions from Nvidia are widely represented in all three groups and enjoy popularity due to their advanced facilities. The company's latest adapter GTX 660 Ti doesn't have its own reference model, so each graphics card manufacturer is able to adjust it exactly to the individual model. Hence, Palit released its own card on the basis of Nvidia GTX 660 Ti adapter and codenamed it JetStream.
