The Nexus HOC-9000 is setting new standards for CPU coolers. The revolutionary HOC-technology puts the 8mm diameter heatpipes directly on the CPU. So the heat of the processor is directly transfered onto the heatpipes. And as heatpipes have a greater heat dissipation power then plain aluminum or copper the heat is transfered with great efficiency. Together with the improved surface area of the aluminum fins, the v-shape area underneath the fan, and the airflow focus, the performance of this cooler reaches an amazing 0.15°C/W. And all this at an ultra low fan speed from 600 RPM (PWM controlled to a max of 1500 RPM). Are you looking for Performance and Silence? Look no further: HOC-9000!       The revolutionary HOC™ technology puts the heatpipes directly on the CPU-core! Heat generated by the CPU is now directly transferred to the heatpipes. With a thermal performance of 0.15°C/W this cooler is leading the market.   Our patented technology bends the diameter of the heatpipe inside a precisely engineered aluminum base.The bottom surface of the heatpipes that will be in direct contact with the CPU is perfectly flat.     Surface 2.0 The aluminum fins of the HOC-9000 have an improved surface area with strategically positioned 'dimples'. The bulgings in the aluminum improve the efficiency of the cooler as the airflow more intensively touches the aluminum.       Airflow focus The airflow of the HOC-9000 is guided to target the CPU core directly for an outshining performance.     V-shape The inner fins of the cooler have a v-shape design to create an open area between the fan and the fins. This open area prevents obstruction of the airflow and preserve a stable fan speed and low noise level.     Rubber fixing The fan is hold securely in place by four soft rubber fan fixings to eliminate resonance and vibrations.     Design tuning Give the cooler your own personal touch by choosing between the 3 different design sticker sets.         Application All Intel® Socket 775 CPU Core™ 2 Extreme / Quad / Duo Pentium™ Extreme Edition D Celeron® D All AMD Socket AM2 / 754 / 939 / 940 CPU Athlon™ 64 / FX /X2/ Opteron™ / Sempron™ Thermal resistance 0.15°C/W     Supplied power adapter For 3-pin motherboard connection or 4-pin power supply connection     Specifications Cooler Specifications Dimensions: Fins: Heap Pipe: Base Material: Weight: 149.3x151x123mm / 5.88x5.95x4.85inch Surface 2.0 Aluminum Alloy with v-shape 4 copper, nickel plated, heat pipes of 8mm HOC technology (HEATPIPE-ON-CPU) 737 gram* Fan Specifications Fan size: Speed: Noise level: Bearing: Rated voltage: Rated current: Power consumption: Warranty: 120x120x25mm PWM controlled, 600~1500 RPM 17 dB(A) ~ 21.6 dB(A) Hypro bearing 12V 0.13A 1.56W 3 years * Maximum weight specified for a cooler is 450 gram for Intel Socket 775 and AMD AM2/754/939/940.
