Zalman keeps on developing high-end cooling systems with a radial arrangement of plates. Its latest product, CPU cooler CNPS9900DF, is considered to be universal in terms of compatibility and implemented facilities. Still, some IT experts view this model as a modification of previously launched Zalman CNPS9900 MAX, although with two fans. In spite of visual resemblance, the company tried to design a truly uncommon cooler, with remarkable specifications and reliability.



Framework Peculiarities


Zalman CNPS9900DF is distinguished by an unusual framework. It's not a traditional vertical tower, as long as heatsink ribs feature fan-like location relative to the central axis of symmetry. Such approach provides for a comprehensive heat dissipation over all key motherboard components due to absence of frames on fans. Heat pipes embrace the cooling plates in a circle, then bend at 90 degrees, piercing the base. At first sight it seems that the framework involves six heat pipes, but …

The release of hybrid AMD processors of A series was announced about a year ago, however, their actual appearance in the market was delayed for a few months. It is a well-known fact that a part of those processors for Socket FM1 platform has got idle graphics block; this part of processors has been codenamed Athlon and Sempron. The two processor models from this series Athlon II X2 221 and Sempron X2 198 can be currently found in PCs manufactured by HP company.



Both processors have been observed in the list of specifications of desktop PCs delivered by HP: Athlon II X2 221 is employed in HP Pavillon p6-1169cx and p6-1226cn models, while Sempron X2 198 is employed in HP Pavillion p6-1152cx, 1230cx, 1231cx, and 1159cx models. The major peculiarity of such technological solution is that HP PCs with those processors are delivered only to the Chinese market.


Two-core Athlon II X2 221 operates at 2.8 GHz frequency, and accommodates 1 MB cache memory of the second level. It is …

Zalman, a well-known manufacturer of CPU coolers, PC cases and graphics solutions, introduces three new graphics card models, codenamed GeForce GTX 600 D5 OC VF1500, GeForce GTX 660 Ti D5 VF1500 and GeForce GTX 660 Ti D5 OC VF1500. All three models are equipped with a brand two-slot VF1500 cooler. Its framework consists of four heatpipes which transfer heat from GPU surface to an aluminum heatsink. This heatsink is accompanied by a couple of 92 mm fans, the maximal rotational speed of which achieves 1500 RPM. If compared with a reference cooler, VF1500 reduces GPU operational temperature at 25 degrees (from 81 to 56 degrees), producing 10 dB less noise (26 dB vs 36 dB).



The first model is based on Nvidia GK106 processor, designed under 28 nm technological process. It is characterized by heightened clock frequencies: nominal 1006 MHz against reference 980 MHz, and dynamic 1059 MHz against reference 1033 MHz.


The other two models, GeForce GTX 660 Ti D5 VF1500 and GeForce GTX …
