Cougar Vortex Fans: the Secret of Success

Nowadays a lot of hardware developers employ Vortex fans from Cougar in the design of various PC components, including CPU coolers and graphics cards. Such demand is primarily explained by an elaborate approach to the fans' framework construction. Profound testing is not the last thing to contribute to the company's success. Indeed, since the launch date in 2011, Vortex line has been enjoying great popularity throughout the world and, especially, on American and European markets.



Therefore, Cougar has designed unique fan impellers that ensure a balanced correlation between such parameters as static pressure, noise level and airflow. The implementation of aerodynamic elements on the internal part of the frame in combination with the grooves on the impellers are able to promote for an improved airflow focusing; this is achieved due to the acceleration of airflow in edge area.


All Vortex fans are based on a hydrodynamic bearing that provides for the prolonged lifetime and …

EKWB Launches a New Water Block for GV-N680SO-2GD

Early August of 2012 was marked for Gigabyte by the release of its one more graphics card, codenamed GeForce GTX 680 SOC (GV-N680SO-2GD). This card can boast the availability of high factory frequencies and quite mighty cooling system. The nominal frequencies have been heightened to 1137MHz, 1202MHz, and 6200MHz for memory. Such outstanding characteristics required the integration of a high-quality and high-performance cooling system which consisted of five(!) fans. This made the card rather voluminous, cumbersome and noisy. That was when EKWB decided to design a dedicated water block to be employed with this remarkable graphics adapter.



Water block EK-FC 680 GTX SOC is housed on a copper base, good-quality acetal cover, and rubber shims as a compressor. The model is delivered with pre-installed fixing stands to facilitate the installation. It should be noted that this water block entirely covers the frontal part of the graphics card, along with the adjacent RAM modules and …

MSI Launches Z87 MPower MAX AC Overclocking Motherboard

All PC enthusiasts and overclockers are now able to enjoy all the privileges of a wireless connection thanks to a new release from MSI. The company’s latest addition to Z87 motherboard series – the Z87 MPower MAX AC – might boast the incorporation of Intel Dual Band module that supports Wi-Fi 802.11 a/b/g/n/ac and Bluetooth 4.0 connections. Moreover, due to the employment of two frequency bands (2.4/5 GHz), the speed of wireless data transfer achieves 867 Mb/sec.



It goes without saying that MSI Z87 MPower MAX AC is based on Intel Z87 Express chipset that supports Intel Haswell CPUs for socket LGA1150. All system components are soldered on a black-and-yellow 6-layer PCB; hardware base is implemented according to MSI Military Class 4 concept. Here, one may find Solid CAP capacitors, Dark Choke throttles, and DrMOS voltage regulators.


The PCB contains four DIMM slots for the installation of DDR3 memory modules (up to 16 GB) with the maximal clock frequency of 3000 MHz. …
