SilverStone Debuts with SST-ST30SF Power Supply

SilverStone Technology has recently introduced its newest SFX power supply unit. Codenamed SST-ST30SF, it features 125x100x63.5 mm dimensions and weighs 800 g only. The unit is estimated for 300 W power and is capable to demonstrate more than 81% efficiency in 230 V networks. High efficiency level allowed the model to gain 80Plus Bronze certificate.



The most uncommon feature ascribed to SST-ST30SF is that it can operate in passive mode if thermal conditions allow. The unit is equipped with a fan of 80 mm dimensional type; it starts rotating only when the surrounding temperature reaches 55 degrees. This promotes for a considerable power reduction and practically silent work when the fan gets disabled. An average noise level on active operation makes up 18 dB.


SilverStone furnishes the new entry with a single +12V rail, estimated for 22 A current. In its turn, +3.3V rail is estimated for 21 A current, while +5V rail – for 20 A current. It should be noted that this unit …

Deepcool is preparing a new cooler with heat pipes

Deepcool production company of inexpensive and quite efficient cooling systems has provided a sample of CPU cooler — Big Frost (tentative codename), which is an extension of current Frostwin model. Previous model has 4 sintered powder heatpipes, which conduct heat from the processor to protect it from overheating. Also, like a new model, it has 120mm fans.



New model has a simple design, but strict, almost «standard», forms will not prevent it from showing a decent performance. It works with less noise and performs an effective cooling. Big Frost consists of a nickel-plated copper base with a miniature auxiliary radiator, six U-shaped copper heatpipes, each of 6 mm in diameter, and two sections of aluminium plates of similar thickness. Pre-installed fans are running at different speeds. One turns with intensity of 1300 r / min (22.6 dB noise), the other — in the range from 900 to 1500 rev / min (21,4-32,1 dB).


Dimensions of construction form 126x136x159 mm, weight — …

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 …
