Be Quiet! to Release the Second Generation of Pure Wings Fans

Listan GmbH & Co. KG, a well-known German manufacturer that releases its hardware products under Be Quiet! brand, is going to introduce the second revision of Pure Wings series of system fans. Entitled Pure Wings 2, the new series includes two models: 120 mm model, featuring 120x120x25 mm dimensions, and 140 mm model, featuring 140x140x25 mm dimensions. Both fans are characterized as entry-level low-noise solutions, which can easily cope with the cooling of all vital system components.

Fans Be Quiet! Pure Wings 2 differ from their predecessors by the doubled number of blades. The latter have got original salient framework that considerably reduces the noise and produces efficient airflow. The fans are based on slide bearings and are estimated for 80.000 hours of trouble-free operation.

Both new-comers draw power via 3-pin connectors and are mounted by means of four screws. The 120 mm model rotates at 1500 RPM speed, producing up to 51 CFM airflow and not more than 19.2 dB …

Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.

The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.

As the advantages of such solution can immediately be noted a lower price, due to less stringent …

Zalman Intros CNPS8X Optima CPU Cooler

Zalman is considered to be a key player in PC hardware field mainly due to a perfect combination of quality, functionality and price tags. CPU coolers are not an exception, since they ensure efficient and low-noise cooling of hard-hitting processors. The company’s latest CNPS8X Optima cooler is all about innovation that turns it around. Improved framework makes the model compatible with practically all platforms from Intel and AMD, save for Intel Socket LGA 2011/2011-v3/1366.

Zalman CNPS8x Optima employs a large heatsink, three copper heatpipes, and a single 92 mm fan. The latter is based on long-life bearing and features 4-contact connector. It is able to rotate at about 1200 RPM, producing not more than 30 dB noise.

The list of innovative technologies integrated into the cooler includes:

— Direct Touch Heatpipe (DTH) technology wherein all three heatpipes are in direct touch with a heatspreader. This accelerates heat dissipation process, enhancing overall …
