PowerColor Intros New Graphics Card with Fling Force Cooler

TUL Corporation, in the framework of its PowerColor brand, introduces a new graphics card with quite an original way of air cooling organization. The new-coming adapter, codenamed PowerColor Radeon HD 7850 Fling Force, employs 'two-storied' cooler of an unusual structure. Along with an aluminum heatsink, copper heat pipes, and a voluminous fan, the manufacturer implemented non-monolithic fan ribs. Their tips are fixed to the main part in a way to change their location relative to the plain of rotation.

On conditions of low rotational speed, tips of the ribs are located at approximately 80 degrees angle relative to the graphics card. On conditions of heightened speed, the ribs become more linear; this way, the impeller diameter enlarges from 92 mm to 95 mm. Such structural approach to the fan framework develops into an improved performance and air cooling effect.

The model is based on Pitcairn chip, developed on Graphics Core Next architecture under 28 nm technological …

Low-Profile Cooler Noctua NH-L12 Review

Noctua, an Austrian developer and supplier of high-end cooling systems, is well-known for the design of versatile products which are able to satisfy the needs of any consumer, starting from average home users and finishing with devotees of overclocking. The recent Noctua creation is the low-profile CPU cooler destined to be employed in HTPC systems and other compact chassis. This cooler is characterized by the horizontal localization of radiator that allows its installation into a quite narrow casing. At the same time, the model is efficient enough to manage high-performance advanced processors.

Design and Framework

Noctua NH-L12 is notable for the classic design and framework. It features 150x128x93 mm dimensions (with two fans) which barely speak of low-profile form factor. NH-L12 is compatible with different CPU sockets, including Socket AM2, AM2+, AM3, AM3+, LGA 2011/1366/1156/1156/775. This cooler consists of horizontal radiator, four copper heat pipes which pierce …

Nvidia Debuts with GeForce GTX 770 Graphics Adapter

Trailed by the flagship GeForce GTX 780 model, Nvidia officially launches one more high-performance graphics adapter of 700 series, codenamed GeForce GTX 770. Albeit the two products are rather similar in design (i.e. the incorporation of identical two-slot cooling system), their layout differs considerably. First of all, GTX 770 employs less efficient graphics core Nvidia GK104-425-A2 (28 nm) with 1536 CUDA cores, 128 TMUs, and 32 ROPs. At the same time this GPU operates at higher frequencies: 1046 MHz (nominal), 1085 MHz (dynamic).

Nvidia’s new entry comes either with 2 GB or 4 GB video memory modules of GDDR5 type. They employ 256-bit interface and ensure high bandwidth of 224 Gb/sec. Memory operational frequency is truly striking, demonstrating up to 1752 MHz (nominal) and up to 7010 MHz (dynamic) index. It should be noted that models with 4 GB modules will cost $50 more than those with 2 GB items (the recommended price makes up $399).

To continue, GeForce GTX 770 …
