UL551
Top Flow Design
Cooling with a fan mounted top-down quickly dissipates heat directly over the heat sink covering the CPU which also introduces additional airflow over motherboard components surrounding the socket such as the VRM and RAM.
Best Matching Fan
Optimal in performance and noise, the 136mm PWM cooling fan balances the best of both worlds to ensure your system is at its best.
