DAS Promise Pegasus R4 Review

Data storage units have become an integral part of PC hardware in recent years. Such conjuncture is simply explained by the rising necessity to store huge amounts of information and transfer the data to various devices. NAS and DAS units have been developed with the intention to solve all storage problems, however, the efficiency of their work is much dependent on the interfaces they use for data transfer. USB 2.0 interfaces are unable to cope with voluminous info; the prevalent now USB 3.0 and eSATA interfaces are efficient only for a single winchester. But when it comes to the management of really huge data blocks, there appears a need for a more advanced solution. Promise Technology dares to solve all vital issues by releasing DAS Pegasus R4 with Thunderbolt interface which is notable for the high and stable data transfer speed with the retention of compatibility.

Preliminary Acquaintance with VGA-Cooler MK-26 V2 from Prolimatech

Prolimatech Inc., an established manufacturer of high-end air-cooling systems, is about to release its new VGA-cooler, codenamed MK-26 V2. The upcoming product will be compatible with graphics cards from AMD manufacturer (up to Radeon HD 7000 Series) and Nvidia (up to GeForce GTX 600 Series). According to the preliminary data, the new cooler models will be capable to manage up to 320W of extra heat to provide for the most optimal GPU cooling down.



The major distinction of MK-26 V2 cooler is its impressive dimensions which equal to 230x146x47 mm. Thus, the cooler will take the spacing of five expansion slots, leaving no room for SLI/Crossfire. The cooler has got a copper base which accommodates six copper heatpipes, 6mm in gauge each pipe. Those pipes pierce two heterogeneous blocks consisting of thin aluminum fins which are designed in correspondence with Buckle Fin technology. The fins are distinguished by the unusual form that is called to promote for better heat removal …

Meet Self-Purified D.F.Vegas Fans from Enermax

Enermax has enlarged its lineup of fans with D.F.Vegas series. The series consists of two models: the D.F.Vegas & the D.F.Vegas Duo. The key differentiation between the two solutions lies in the current intensity as well as LED backlights. The first new-comer is equipped with 12 blue diodes, while the second model houses 12 red and 12 green diodes.



Enermax D.F.Vegas fans boast the implementation of self-purification technology – Dust Free Rotation (DFR). During the first ten seconds of operation the fan rotates contrary clockwise and then returns to standard rotational mode. That is how dust and litter is removed from the blades. If there is a need in manual cleansing, the blades can be easily detached.


Both fans are designed on Twister Bearing with MTBF index of 160 thousand hours. The frame accommodates a single 4-pin connector which supports PWM technology. Hence, it’s possible to limit the maximal rotation speed by 1100/1300/1500 RPM by means of a dedicated …
