The Nexus FLC-3000 R2 cooler combines some of the most advanced technologies in the market used for CPU coolers. Heat pipes at an 30deg; angle with HOC-Technology, SkiveTek and 3 types of ultra-thin fins combined with a real silent PWM controlled fan delivers ultimate performance which has never been this quiet before. FLC 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 92mm fan is PWM controlled and the speed can vary between 900 and 2500 RPM creating a noise-output of an inaudible 15 dB(A) up till a still truly quiet 24 dB(A). You should really experience it yourselves; fan, fins and heat pipes at a 30° angle, creating a perfect flow over the motherboard.     Highlights Heat pipe-On-Core Technology 4 x 6mm copper heat pipes 3 types of ultra-thin aluminum fins SkiveTek Heatsink Technology for Socket LGA1366/1156/775 and AMD AM3/2 Push-pin mounting for Intel PWM controlled fan 30° angled heat pipes Universal application Intel 1366, 1156, 775 AMD AM3, AM2 Dimensions 128 x 105 x 119 mm    [L x W x H] 5.04 x 4.13 x 4.69 inches Materials    Pure copper base Pure copper heatpipe Pure aluminum heatsink Pure aluminum fins Weight 450 gr / 15.9 oz Heat pipe  4 heatpipes of 6 mm / 0.236 inch diameter Fan size 92 x 25 mm / 3.6 x 0.9 inches Fan voltage 12V Fan function PWM controlled by fan Fan speed 900 to 2500 RPM (± 10%) Fan connector 4-pin LED's 2 x orange LED in fan center core Noise level 15 ~ 24 dB(A)* HOC and SkiveTek explained
