Sapphire Offers an Alternative Radeon HD 7870 GHz Graphics Card

Sapphire Technology, a renowned supplier of graphics solutions, has added an alternative model of AMD Radeon HD 7870 GHz Edition to its graphics cards model line. The new model is primarily notable by the integration of a two-slot Dual-X cooler that facilitated the process of entitling: Sapphire Radeon HD 7870 GHz Dual-X Edition. This cooler consists of a voluminous aluminum heatsink, a couple of large fans, and a few copper heat pipes which are covered by a plastic lid.



Graphics card Sapphire Radeon HD 7870 GHz Dual-X Edition is based on Pitcairn chip with 1280 current processors; it is developed under 28 nm technological process and Graphics Core Next architecture. The core is able to operate at the nominal 1000 MHz frequency. Blue printed circuit board is the heart of the adapter. PCB is designed particularly for PCI-e 3.0 x16 bus and houses 2GB of GDDR5 memory with 256-bit interface. The memory is capable to achieve the clock frequency of 4800 MHz.

PC Chassis SilverStone Sugo SG09 Review

Model SG09 is the ninth chassis of Sugo series designed by SilverStone. Upon the whole, the series consists basically of compact parallelepiped casings that presuppose the integration of small-sized mini-ITX motherboards only. Still, Sugo SG09 features more voluminous dimensions (354x220x295 mm) and cubic-like casing that widens its compatibility area a bit. All previous Sugo models were perceived primarily as compact solutions with a quite aesthetic design. But Sugo SG09 positions itself as a reliable platform for a powerful PC system.



Layout


Chassis SilverStone Sugo SG09 has got rather unusual layout due to the need to accommodate a full-sized PSU, a lengthy graphics adapter, a voluminous CPU cooler, and some kind of data storage system in a casing of 23 liters in capacity. As a result, the developers created a one-volume casing with vertical PSU in the frontal part, vertical motherboard tray, and vertical bays for hard drives located on the reverse side of the tray. The …

Cougar Vortex Fans: the Secret of Success

Nowadays a lot of hardware developers employ Vortex fans from Cougar in the design of various PC components, including CPU coolers and graphics cards. Such demand is primarily explained by an elaborate approach to the fans' framework construction. Profound testing is not the last thing to contribute to the company's success. Indeed, since the launch date in 2011, Vortex line has been enjoying great popularity throughout the world and, especially, on American and European markets.



Therefore, Cougar has designed unique fan impellers that ensure a balanced correlation between such parameters as static pressure, noise level and airflow. The implementation of aerodynamic elements on the internal part of the frame in combination with the grooves on the impellers are able to promote for an improved airflow focusing; this is achieved due to the acceleration of airflow in edge area.


All Vortex fans are based on a hydrodynamic bearing that provides for the prolonged lifetime and …
