Integrated Aluminum Backplate Heatsink with Dual PWM Fans for RTX 3090 3080 3070

Purpose: Designed to address high temperature issues on the back memory of RTX 3090 graphics cards. Construction: Single-piece integrated aluminum backplate radiator—no need to splice parts together, simple to mount. Cooling fans: Equipped with standard 5010 dual fans providing up to 20CFM at full load. Fans use low-noise hydraulic bearings and support PWM speed control, allowing both dynamic and static operation. Connectivity and control: Fan cable uses a 4-pin connector, identical to a regular chassis fan, and plugs into a motherboard fan header such as a SYS fan. Fan operation and speed can be enabled and adjusted from the motherboard BIOS. Speed range: 1500 ~ 5000rpm (adjustable). Thermal pad guidance: If the GPU backplate is flat, use a 0.5mm thermal pad; if the backplate surface is uneven, use a 1mm thermal pad.
