Patented LED Design The built-in LED ring features great light coverage, uniform color & brightness, & is compatible with selected motherboard RGB software (ASUS, ASRoc K, BIOSTAR, GIGABYTE & MSI). Reliable Hydraulic Bearing The hydraulic bearing self-lubricates with a high quality, friction-reducing substance, which lowers operation noise while improving thermal efficiency. The seal cap prevents lubricant leakage & extends the lifespan of the unit. Superior Heat Dissipation Come with 0.4mm thickness aluminum fins with 2.2mm air gap, & 4 x & Oslash;6mm solid copper heat-pipes for maximum heat conductivity. The heat-pipes are in continuous direct contact with the CPU to ensure fast & efficient heat dissipation. The tower’s side flow design also enhances the thermal performance. Thermal Image Demonstrates for Heat Distribution The Riing Silent 12 RGB delivers outstanding cooling performance, keeping the temperature between 30&8451; & 32.5&8451; (ambient temperature is 20&8451;) @ Intel Core™ i 7-4770K 3.8 G Hz at full load. Special-Designed Fan Clips Attach the fan to the CPU cooler tightly & evenly with the included special-designed fan clips, which also make assembly & dismantling way much easier. Anti-Vibration Mounting System In-mold injection anti-vibration rubber pads provide a hassle-free usage with 80% protection coverage for all corners Non-Interference Cooling Design The non-interference cooling design eliminates the co-existing problem of high performance RAM & CPU coolers to achieve the best RAM clearance.
