Meeting New Cooling System Brocken 2 from Alpenfoehn

Only a couple of weeks are left till the official release of a new cooling system Brocken 2 designed by Alpenfoehn. This is a long-awaited launch, since the fist version of the system, entitled Brocken, was honored to gladden the audience long time ago. Hereby, Brocken 2 has got a wee bit modified framework, if compared with the predecessor. Its dimensions together with a fan equal to 146x100x165 mm.



The base is shaped by means of five 6 mm copper heat pipes, tightly pressed together. Aluminum plates of the heatsink seem to be ‘cut’ in the center, unlike the one-piece construction of plates implemented in Brocken.


Active cooling power is ensured by a nine-blade fan of 140 mm standard size, known as WingBoost 2. The fan supports PWM technology that allows altering its rotational speed within the boundaries of 400-1100 RPM. Its activity stimulates the airflow index of 109 CFM, while the noise level barely achieves 19.6 dB (A). WingBoost 2 features small distance between …

Liquid-Cooling System Zalman LQ315 Review

A few months after the last release of water-cooling systems, Zalman introduces a new series of products with a title attribute LQ3xx. The series consists of three models, LQ320, LQ315 and LQ310, which differentiate themselves primarily by dimensions. The senior cooler (LQ320) features 32 mm water block and 52 mm heatsink, the medium LQ315 cooler features 38 mm heatsink and analogous in dimensions water block; the junior cooler (LQ310) is the tiniest one and features 28 mm heatsink and water block. Zalman LQ315 greatly resembles its predecessor, CNPS20LQ, in design, however, is ready to offer some improved options, if compared with the previous cooler generations.



Design and Framework


Like any other water-cooling system, Zalman LQ315 consists of a water block combined with a pump and joined with a heatsink by means of flexible tubes. The water block is notable by the availability of 'Z' logo on its surface that is lighted blue during operation. Its round base, made of …

Intel is preparing a quad-core Core i7-3740QM, 3840QM and 3940XM

In late September — early October, Intel plans to update the lineup of Core i7 processors on the cores generation Ivy Bridge (22 nm). It is expected that within a few months users will witness the announcement of the CPU for laptops Core i7-3740QM, 3840QM and 3940XM, which will replace released in April 3720QM, 3820QM and 3920XM, respectively.



According to the information from web resources, the trio will receive an increase of 100 MHz from the predecessors, retaining the previous TDP and probably the recommended price. A common feature of the new processors is four x86-cores that handle data in 8 threads (Hyper-Threading).


Core i7-3940XM operates at a nominal frequency of 3 GHz, equipped with 8 MB cache of the third level, two-channel controllers DDR3-1333/1600, graphics subsystem Intel HD 4000. There is support for dynamic overclocking Turbo Boost, Virtualization VT-x and VT-d, new commands AES and instructions AVX. TDP 3940XM is 55 watts.


Core i7-3840QM has almost …
