Raijintek Intros High-Efficiency CPU Cooler Entitled Nemesis

Raijintek, a young but future-proof company, has recently showcased another addition to its CPU cooling solutions – the Nemesis. This is a tower-like model targeting initially overclockers and PC enthusiasts. It features 140x130x166.5 mm dimensions and weighs 1050 g. The fans of extreme cooling can enjoy all privileges of Nemesis right now, since it’s already available for pre-order in the European market for the retail price of 60 EUR.

Raijintek Nemesis consists of a copper base, five nickel-plated U-shape heatpipes, and a pair of asymmetric aluminum heatspreaders, accompanied by two fans of 140x150x25 mm standard. The fans are manipulated by powers of PWM technology, so their speed might vary from 600 RPM to 1400 RPM.

Their unified efficiency achieves 119 CFM of produced airflow; that is quite enough to cool down rather hot CPUs. Moreover, the framework allows to utilize the cooler as in active, so in passive mode when the loading is low.

Arctic Cooling Unveils New Freezer i32 & A32 CPU Coolers

Arctic Cooling AG replenishes its line of CPU coolers with a couple of new-comers. The Freezer i32 and the Freezer A32 feature analogous dimensions (123x95x150 mm), but are targeting to work with different platforms. The first model is compatible with Intel Socket LGA 2011 and 115x platforms, whereas the second version is predestined for the CPUs targeting AMD AM2/AM2+, AM3/AM3+, FM1 and FM2 platforms.

Arctic Cooling Freezer i32 & A32 consist of an aluminum heatsink with 45 thin plates and four U-shaped 6-mm copper heatpipes which support direct touch technology. It goes without saying that these coolers come equipped with a fan. This is a 120 mm propeller that supports PWM technology; the latter enables the change of rotational speed from 0 to 1350 RPM. The maximal TDP level of the catered CPUs should not exceed 150 W.

A dedicated bearing technology with alloy/lubricant combination provides for a lower friction and higher heat dissipation efficiency. The nominal delivery …

New characteristics of co-processors Xeon Phi

For several years, developed Intel Larrabee graphics cards have changed its destiny, and now proudly referred to coprocessors Xeon Phi. The June announcement gave a very rough idea of ​​their characteristics and applications (highly specialized servers and workstations). Now some details will be revealed.

Bboosters Xeon Phi will be available in versions with 57, 60 and 61 core. There are in general 64 computational units, but some of them will be disabled. Depending on the number of cores the cache size varies from 1.8-1.9 MB first level and 28-30,5 MB second. The volume of onboard GDDR5 memory is 3, 6, and 8 GB.

Intel Xeon Phi device will operate on a low clock rate from 600-1100 MHz for the lower 57-core models with 3 and 6 GB of GDDR5, to the 630-1050 MHz or more for the older 60 — and 61-core board with 8 GB of RAM. Effective memory frequency will be in the range of 5-5.5 GHz. Support for dynamic overclocking Turbo Boost will be provided by reasonable balance of …
