Specialized 140m FDB Fan: Designed with a quiet and efficient 3-phase 6-pole fan motor, the 140mm fan provides optimal air flow at a low noise level. Industrial Grade Thermal Paste: A tube of DeepCool's industrial grade DM9 thermal paste is included. Maximum Compatibility: Supports the vast majority of modern Intel and AMD CPUs while the relocatable 120mm fan ensures maximum compatibility for high profile RGB RAM modules. The Flow Below: Due to the center 140mm fan sitting deep into the heart of the Assassin 4S WH, there is a lower flow of air that provides additional cooling to the toasty surrounding VRMs.
