The Nexus LOW-7000 cooler combines some of the most advanced technologies in the market used for CPU coolers. Heat pipes, SkiveTek and ultra-thin fins combined with a real silent PWM controlled fan delivers ultimate performance which has never been this quiet before. LOW coolers are crafted out of the purest aluminum and copper materials. The heat sink covering the heat pipes and the copper base is made using SkiveTek technology. We have managed to apply the best technologies at the best position on the cooler. And the result is astonishing... The 120mm fan is PWM controlled and the speed can vary between 500 and 2000 RPM creating a noise-output of an inaudible 15 dB(A) up till a still truly quiet 24 dB(A) The LOW-7000 is an ideal cooler for your HTPC the ultra low, only 7cm high, cpu cooler with a silent 120mm fan Nexus FLC-3000 Features         Copper Base 4 x 6mm Copper Heat Pipes SkiveTek Heat Sink Ultra-Thin Aluminum Fins Socket 775/1366 PWM Controlled 120mm Fan Only 7cm high Perfect for HTPC's   Nexus FLC-3000 CPU Cooler Cooler Specifications Universal application Dimensions   [L x W x H] Materials       Weight Heat pipe   Intel 775, 1366 138 x 123 x 70.3mm 4.84 x 5.43 x 2.77in Pure copper base Pure copper heat pipe Pure aluminum heat sink Pure aluminum fins 475gr x 16.8oz 4 heat pipes of 6 mm / 0.236 inch diameter   Fan Specifications Fan size Fan voltage Fan function Fan speed Fan connector Bearing Type Noise level   120 x 20mm / 4.72 x 0.79in 12V PWM controlled by fan 500 to 2000 RPM (± 10%) 4-pin Sleeve Bearing 15 ~ 24 dB(A)*   Noise level test When Nexus tests the noise level of their products, they do this in an ISO-certified chamber and according to a prescribed set-up. Measurement is done using a Brüel & Kjær microphone. It is important to know that the background noise in an official noise test chamber is approximately 15 dB(A). These are the best possible conditions for these tests and hence you should always be aware when a manufacturer is claiming dB(A) values that are lower then 15 dB(A). Because how where they able to measure this? Nexus provide the real figures, from the actual tests. Can it get any more reliable? Judge for your self.   Nexus provides the exact details of our noise level test as they feel dB(A) values are difficult values to compare as there are many ways of testing and calculating. In the market there are a lot of unrealistic dB(A) value-claims which are often calculated by means of extrapolation. This in fact does not give a realist view of the fans noise level performance.
