Cooler Master CPU Cooler GT V6 - Technical criteria

What the veteran at the periphery and cooler market Cooler Master, in recent years in the power supply and is managed primarily housing segment to win namely extravagantly successful product creations favor the buyer could be achieved in the highly competitive area of the processor cooler only limited. The following are some technical criteria :

• Cooler Master V6 GT 120-mm-Tower CPU Cooler
• Dimensions without fan: 131 x 62 x 154 mm (L x W x H)
• Dimensions with double-fan: 131 x 120 x 165 mm (L x W x H)
• Weight with standard fan: 940 grams
• Six 6-mm heat pipes in U-bending
• Nickel plated aluminum fins and copper base
• 55 x 0.3 mm plates, spacing 1.5 mm
• Two 120-mm-type fan (FA 12050H12LPD CM)
  
  • 4-Pin PWM function (a connector for both fans)
  • Speed range: 800-2200 rpm
  • Output: 57.5 to 158.4 m³ / h

This was based on more complicated and costly structures and, consequently, high prices, but only conditionally. The V6 GT Cooler Master will now find their way back on track.

Behind the opulent plastic dress of the Cooler Master V6 GT lies a narrow 120-mm single-tower heatsink from nickel-plated aluminum fins, six heatpipes and a copper heat absorption. The only 0.3 mm thick aluminum fins, which have a distance of about 1.5 millimeters each point, while a slight horizontal twist in order to use the adjacent air flow better. Another special feature is the inclusion of the Cooler Master heat pipes to the plate layout. While the U-shaped bent-heat-conducting capillary mostly linear or slightly offset from each other to penetrate the slats levels, this happens when in a GT V6 eponymous V-formation. This is expected to be more efficient heat distribution and rapid removal by the air flowing around. Otherwise, plastic dominates the action in the V6 GT. At the top plate Cooler Master has fixed a plastic cover that provides light with a central strip either for visual emphasis in the dark PC case.

With the help of the hood prominently incorporated Cooler Master buttons lets you choose the lighting color between red, blue and white and blue. In addition, a stop function is available. The power supply of the lighting is a 4-pin power connector. The attachment of the two 120-mm-type fan is also realized through the plastic housing by means of appropriate connectors. While the fan removal order when removed relatively easily goes from the hand, is on the mounted cooler and motherboard in the case because of the high space requirements already asked a lot more tact. Two 120 mm fans in "push-pull formation" effect the active circulation of air. At first, the back plate is positioned on the motherboard and secured with four screws on the bottom of the front end aligned mounting brackets.

The PWM-capable models work manually controlled to a considerable speed range between 300 and 2200 r / min and can be operated simultaneously using the included Y-cable with a 4-pin connector. A slight vibration isolation between fan and adjacent heat sink by means of small rubber bumpers on the fan frame. Cooler Master familiar with the V6 GT befitting a rear mounting plate for AMD and Intel, which is working with a cross-platform back plate, but through specialized counterparts for the front pages. The expansion of the motherboard from the case is of course necessary. Intel users need to adjust the variable before mounting bracket for socket 775, 1156 and 1366. This is based on the metal bracket bolted realized something complicated and cost compared to competing solutions considerably more effort.

This is a bit of tact and quiet operation are essential. If the holding frame mounted, the V6-GT heatsink (the fan frame, including their anchorages, must first be removed) to be attached with conductive paste prepared by using the CPU and two-point bridge screwed each other. Here one has dismantled despite fan because of the protruding plastic cover something a little leeway in the use of a Phillips screwdriver. Ultimately, the 120-mm fans with their mounts are re-engaged to the heat sink and connected via 4-pin connector to power. Thus, the assembly is completed. With plastic cover of the Cooler Master V6 GT significant measures 165 mm in height. Many smaller casings while already having problems. Before buying you should therefore be thoroughly informed about the housing compatibility.

The popular quad-core CPU generated in standard mode (2.66 GHz, 1.2 V core voltage) according to the datasheet is 130 watts at full capacity and thus on the level of our previous processor, the Intel Core 2 Extreme QX6700 Kentsfield (2.66 GHz, 1.35 volts V-Core). As the motherboard comes with matching DX58SO Intel's "Smack Over" is used, which we also already in the report for Intel Core i7 have presented. As a suitable case for the test assembly in the closed, stagnant ATX System Case King provides us with the Silverstone TJ-09S , a spatially generously sized basis. In addition to the generous space available here is mainly the position of the power supply on the bottom crucial to a fair test conditions because of the fans of our 650-watt Lian-Li Silent Force power supply can develop there is no effect on the processor cooler.

The measurement of the volume occurs in the particular operation of that cooler (the fan is powered by a passive power supply) in 40-cm intervals with a Voltcraft-320 sound level meter that the noise emitted by the known A-weighting curves in a range from 30 to 130 decibels interpreted. The overall volume of the measuring room with subjectively perceived silence is 30.4 dB (A). Above this threshold, the noise emitted from the radiator can not be resolved by the instrument. To about 35 dB (A) depending on the sensitivity of the user can rate and character of the sound to assume that the fan noise when the housing is closed, respectively not be perceived any more. 40 dB (A) of our scale, the noise can be clearly heard to very clearly, from 50 dB (A) starts the very disturbing area.

To obtain the most meaningful picture of the cooling characteristics of the subjects, we test the coolers in various CPU modes that target due to different clock speeds and operating voltages and case ventilation intensities tasks to the respective products. For example, while in "standard mode" the demands of a retail coolers are still relatively reasonable, few can top cooler can withstand the demands of "performance" mode with low active speed. Supplemented the list of "semi passive test", in which disabled the CPU fan and using only the air from the only case fan at different speeds is guaranteed. Apart from that we use, in analogy to our processor tests, the CPU load on Prime95 back, the instances of the SmallFFT tests are frequently conducted in the highest Heating load Core i7 CPU test out eight.
