The three gifts of the binding with a price of the manufacturer of just under 50 € provided Tower cooler made of the well-stocked assembly utensils for AMD and Intel systems, including a syringe, thermal grease and an installation manual, the rubber fan mounts for up to two 120-mm Fans with spare copies, and a pin adapter for power supply direct power to the PWM fan. The following are some Technical features :

• Symmetrical 120mm Tower Cooler in hybrid design
• Aluminum fins, copper heatpipes
• Five-fold 8-mm-U-heatpipe design with direct-touch technology
• Fin spacing: 1.5 mm
• Dimensions: 131 x 155 x 96 mm (W x H x D)
• Weight: 860 g
• 120-mm-type ventilation
  • PWM function
  • Transparent Blades, blue LED lighting
  • Maximum of 1500 rpm at 137 m³ / h
  • Interceptor by rubber strings
  • Cable length: 33 cm

The North Face EKL starts the attack on the cooler crown. For this purpose, the manufacturer has designed a powerful cars, which occurs by virtue of defiance with a raised, progressive styling and appearance. A hard, sharp lines, the broad radiator and the matt surface finish nickel-plated carbon-look characterize the stocky 120-mm-Tower, who knows himself managed to stand out from the mass market. Since the large-Clock'ner EKL relies on the heat-pipe Direct Touch technology, which sharpened the implemented in U-bending heat pipes carefully directly on the CPU heatspreader surface lie.

Since the large-Clock'ner EKL relies on the heat-pipe Direct Touch technology, which sharpened the implemented in U-bending heat pipes carefully directly on the CPU heatspreader surface lie.

This procedure generally reduces performance-reducing material transitions, however, poses problems in the form on the uneven nature of the bottom plate. In the north wall, with its clean cut heat absorption of five 8-mm capillary, however, barely scratches or bruises to identify. Nevertheless, the manufacturer recommends to use a bit more thermal compound to fill any faults. In addition, it must be mentioned that really, for example, when using an Intel socket 775 processor only three of the five heat pipes in contact with the CPU surface and therefore fail in these CPUs, the performance of the north wall a little lower. Only larger heat spreader of an AMD Phenom or Core i7 processor actually touch all five heatpipes of the cooler and call as from its true capabilities.

Another special, the very well-made northern wall has a laterally closed slats leadership. This promises to be the airflow through the introduced distance of about 1.5 millimeters aluminum cooling units cause. Disadvantage of this design, especially the ventilation should be evident in weaker, however, be a growing friction, the (600 rpm or less) with relatively large power losses in the Super-Silent-going hand in hand. The North Face comes with 120-mm-type ventilation. EKL here relies on a transparent PWM model that operates approximately in the speed range between 800 and 1500 rpm and provides the basis of the four-LED-driver for cool-blue light activated. The suspension of the fan with the aid of four relatively soft rubber strings, which are only in implementing the slats hung on the heat sink and then pulled through the holes of the fan frame. This works very well and also effectively dampens vibrations occurring. EKL lodged with the north wall of ten of these rubber-strings, making sure there is an optional double despite ventilation with possible failure of a string of replacement. As is proper, the nearly 900-gram north wall on both Intel-based back plate and on AMD platforms bolted to the motherboard. Is especially gratifying for AMD users with transversely positioned base that EKL has paid attention to the orientation of the radiator to the rear wall.

The many cards is generally easily installed. With detached main board, the threaded bolts through the holes of the back plate and fixed, laid out the insulating and the construct from below through the mounting-holes on the motherboard. Now the fan-less north wall of the somewhat more generous fitted with thermal compound prepared CPU and on the basis of the four spring-thumb-screws locked alternately. This is done first by hand and should be completed with a screwdriver. Good news: Even with the cooler can now be built motherboard later, about to change the CPU or the thermal compound, dismantled and replaced. With a height of about 155 mm counts north wall is not of the highest tower coolers on the market. However, it should be thoroughly checked before the purchase, whether the hot rod in the housing takes place.

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. Shall elaborate the only case fan with the Scythe S-Flex 800 is a silent 120mm rear discharge model and supports the CPU cooling in the active and semi-passive test modes.

The temperature measurement results are often quite strongly linked to the test platform used and can vary significantly depending on the configuration. You should only as a guide and gross trend, however, are not regarded as absolute. 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. Furthermore, we generated by the fan wind speeds measured with an anemometer and indicates the maximum speed as an indicator of the volume of fluid. From this value can be obtained on the conclusions generated by the fan air flow rate.

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 Core i7 CPU test out eight. It goes every half-hour test run ahead to the thermal equilibrium a warm-up period of 45 minutes. In this system temperatures from Everest diagnostic tool to document, which is used to evaluate the method of core temperature maximums over the entire test run.
