Features: Brand new and high quality 4 copper pillars CPU cooling fan,Pure copper heat pipe quickly dissipates heat. 4 U-shaped bent sintered pure copper heat pipes , arranged symmetrically on the horizontal and vertical axes , effectively reduce the performances loss caused by redundant bending times and angles. Heat pipe direct contact process design,The zero contact of the heat pipe is conducive to the first time the heat generated by the CPU is transferred to the surrounding. Pure aluminum fins have excellent thermal conductivity,neat and beautiful , strong and durable Wide range of compatibility,precise and efficient heat dissipation.
