Zeiwohndc Integrated Backplate Heatsink with Dual PWM Fans for RTX 3080 / 3090

Overview: Zeiwohndc's integrated backplate heatsink is designed for NVIDIA RTX 3080 and 3090 cards and specifically addresses high temperatures on the 3090 back memory. One-piece back plate radiator: a single integrated unit that requires no patching and is simple to install. Cooling fans: fitted with standard 5010 dual fans delivering up to 20CFM at full load, using low-noise hydraulic bearings. Fans support PWM control for both dynamic and static operation. Connectivity and control: the fan cable uses a 4-pin interface compatible with standard chassis fan headers (for example a SYS fan on the motherboard). Fan speed can be managed from the motherboard or enabled in BIOS, with an adjustable range of 1500 ~ 5000rpm. Thermal pad guidance: if the graphics card back plate is flat use a 0.5mm thermal pad; if the backplate surface is uneven use a 1mm thermal pad.
