All-in-one liquid CPU cooler with pre-filled coolant offers best usability and maximum cooling performance for powerful PC systems with multi-core CPUs. The shunt inside the micro fin structure minimizes the "Boundary Layer" effect, eliminates hot spots much quicker and ensures perfect heat dissipation.Stable performance, higher heat conductivity and tightest fit to the CPU thanks to the extruded cold-plate design. Low operating noise and efficient cooling performance thanks to long-lasting ceramic bearing pump.The Enermax twister pressure fan is designed especially for the use on radiators. Due to its innovative shape and the quality structure, the twister pressure fans achieve an exceptional high cooling performance and generate minimum noise. Easy fan speed customization according to the system requirements. With a small switch at the back, the peak speed can be changed in three steps.
