Features: The memory cooling fan can effectively reduce the temperature of memory modules to preventsystem crashes or damage caused by overheating, thereby ensuring systemstability and reliability. The memory cooling fan adopts a low noise design to reducesystem noise and improve user comfort. The installation is very simple, just fix the fan on the memory slot, without any additional tools or skills. Supporting the connection of the motherboardPWM temperature control interfaces, intelligently adjusting the fan speed basedonCPU temperature has the advantages of energy conservation and noise reduction. When theCPU temperature increases, the fan automatically increases its speed and quickly cools down. When theCPU temperature decreases, the fan automatically reduces speed, saving energy and reducing noise. Suitable for DDR/DDR2/DDR3/DDR4/DDR5 and other types of memory to meet the needs of different users.
