1. The ram memory cooler features an active cooling design that significantly improves memory cooling efficiency, supporting higher frequencies and more stable operation. 2. Its rectangular shape, thick metal material, and textured paint process precise molding to accommodate memory modules up to 54mm in height. 3. This ram memory module cooler is equipped with two 50mmx50mmx20mm fans with hydraulic bearings, featuring 4Pin PWM/3Pin ARGB connector. The fan speed ranges from 600 to 3600 RPM10%, with a lifespan of equal 20000h@25. It delivers an airflow of 1.3-9.11 CFM and a static pressure of 0.17-1.6 mmH2O, with a maximum noise level of 22.4 dB(A), ensuring quiet and stable operation. 4. The ram radiator heatsink includes ARGB lighting effects, It supports addressable 5V 3-pin ARGB interfaces from compatible with /, and others for software-controlled lighting synchronization. The system combines aesthetics (16.8 million ARGB colors) and intelligence (PWM smart fan speed adjustment system for energy saving and noise reduction), quickly dissipating heat from the motherboard and power supply. Product application: It is recommended to use with water cooling products under for ATX and for MATX motherboards Note: The memory height limit is 54mm. If you use an adapter copper column, the height will increase by 8mm Installation sequence: 1. The fixing screw replaces the motherboard fixing screw and screws it into the corresponding motherboard fixing hole 2. The fixing screw is screwed into the fixing screw to fix it If the copper column of the chassis itself is an M3 inner bud, you need to use an adapter copper column to screw it into the fixing screw first and then screw it into the motherboard copper column hole. The luminous part of the product in the picture is ARGB lighting effect; the actual product may have color difference due to different light or display screw colors are random,don't accept the specified color Colour:Black Material:Iron+Plastic Package Contents: 1x radiator with wire 1pack x mounting screws Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
