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 …

SilverStone Outs Strider Platinum Power Supply Units

SilverStone technology is about to launch three new PSUs which join Strider Platinum family. The ST55F-PT, ST65F-PT and ST75F-PT offer 550 W, 650 W and 750 W power correspondingly. The new-comers are housed in a classic black chassis, featuring 150x86x140 mm dimensions, and are based on Sirtec platform. The latter complies with ATX 12V 2.4 requirements. Moreover, all models boast 80Plus Platinum certificate, since their efficiency achieves 94% in 230V networks.

SilverStone Strider Platinum units feature an entirely modular design. Cooling is ensured thanks to a pre-installed 120-mm fan that rotates at 1500 RPM on 100% loading and at 1000 RPM on 70% loading. It produces not more than 18 dB noise and might operate trouble-free for some 100 thousand hours.

These PSUs come equipped with all-new safety options, including Active PFC, overvoltage, overloading, overheating, and short circuit safeguards. The list of integrated connectors embraces standard ATX, EPS 12V (4+4)-pin, a …

Motherboard Biostar A55MD2 Review

Good overclocking facilities are what the majority of customers look for in contemporary motherboards. In this light, the manufacturers establish various price ranges, depending on the product’s overclocking potential. As usual, boards from budgetary lines cannot boast such potential, though there are some exclusions. Biostar A55MD2 is considered to be one of the cheapest solutions for FM2 platforms. Still, its layout marvels by the availability of CPU boost facilities, as well as gigabit network interface.

Design and Layout

Motherboard Biostar A55MD2 distinguishes itself by rather compact dimensions: 226x178 mm (uATX form-factor). The model accommodates an amplifying board that is made of a metallic fusible element. The chipset is cooled down by a small-sized aluminum heatsink, while field transistors are avoid of any cooler. This might signify about some inconsideration pertained to thermal environment. Power supply activity is realized by means of 24-contact and …
