Fractal Design comes out with a new series of liquid coolers. The ‘Kelvin’ lineup is introduced by three models – T12, S24, S36 – which are differentiated by the amount of fans. The triple is targeting any up-to-date system based on Intel or AMD CPUs (Intel LGA 2011/1366/1150 and AMD FM2+/FM2/FM1/AM2+/AM2/AM3+/AM3). Their price is set at $99.99, $119.99 and $139.99 for one-fan, two-fan and three-fan model correspondingly.



Fractal Design Kelvin coolers boast an enclosed design that does not require additional maintenance during operation. They consist of a waterblock with a copper base, a powerful pump with a ceramic bearing, a copper heatspreader, and 1/2/3 Silent HP fans (of 120 mm dimensional type). The latter support PWM technology that adjusts rotational speed within 700-1700 PRM ranges; they are ready to produce up to 62.4 CFM airflow at 26.9 dB noise.


It should be noted that ‘Kelvin’ coolers might be expanded by new components. For instance, the T12 is …

In the last couple of years, the chassis with the division of the interior into two zones has become very popular. In the lower part, as a rule, there is a power supply unit and drives, and in the upper part – all the other components. Almost all manufacturers now have similar models. This fashion did not pass around LogicPower, where it was embodied in the case of LP 7777 from the Perfect series.

Chieftec, a renowned manufacturer of power supply units, has recently introduced a series of new PSUs, codenamed BPS, which included five different models. The two models differ from other items in color, dimensions, applied fans, and belonging to the lower PSU segment. The other three products belong to the high-end segment and own outstanding characteristics. Chieftec BPS-650C2 belongs to the high-end echelon that is confirmed as by its internal integration, so by general specifications.



Integration


PSU Chieftec BPS-650C2 employs modular system of cable connection and is notable by 650W of output power. The external design of the model did not outlive any dramatic changes, except for the availability of large stickers on the PSU casing. Quite the contrary, the integration has been given a completely new touch. BPS-650C2 is based on a new advanced platform developed by CWT. The manufacturer employed DC-DC converters for +3.3VDC and+5VDC channels. Those converters are …
