Thermaltake Contac Silent 12 is a budget CPU cooler with excellent cooling performance, featuring a 120mm PWM controlled fan, high airflow fan blades, long life hydraulic bearing, low-noise operation as well as non-interference cooling design. The Contac Silent 12 supports all the latest Intel and AMD CPU socket. High Airflow Fan Blade Design The fan blades are engineered to achieve the optimal cooling performance and generate large volume of air passing through the heatsink at any angle. Long Life Hydraulic Bearing for Reliable and Silent Operation The hydraulic bearing self-lubricates with a high quality, friction-reducing substance that lowers operation noise and enhance thermal efficiency. The seal cap prevents leakage of the lubricant and improves the lifespan of the unit. Superior Heat Dissipation Optimized 0.4mm thickness aluminum fins with 2.2mm air gap, and 4 x ÃËœ6mm solid copper heat-pipes are designed for rapid heat dissipation, allowing maximum heat conductivity. The tower''s side flow design delivers the best cooling performance. In addition, the heat-pipes are in continuous direct Contac with the CPU to ensure fast and efficient heat dissipation. Optimized Silent Operation The Contac Silent 12 comes with a LNC (Low-Noise Cable) that can reduce 24% of noise level and 27% of fan speed. Special-Designed Fan Clips The fan clips allows the fan and the cooler to combine tightly. Also, the clips make assembly and dismantling more easily in process. Non-Interference Cooling Design The new Contac Silent 12 solves the co-existing problem of high performance RAM and CPU coolers, achieving the best RAM clearance. Universal Socket Compatibility All-in-one back-plate design offers universal Intel and AMD socket compatibility.
