Bykski 480mm Copper Radiator RC Series High-performance Heat Dissipation 100mm Thickness for 12cm Fan Cooler, CR-RD480RC-TK100

A 480mm radiator with 100mm fin-stack depth is the heat rejection capacity that a serious AI workstation loop requires. The Bykski CR-RD480RC-TK100 uses full copper construction — tubes, headers, fins — because copper transfers heat to air more efficiently than aluminum, and efficiency at the radiator directly determines how cool every component in the loop runs. For dual-GPU systems pushing 700–900 W of combined thermal load, 480mm is not oversized: it is appropriate.

The RC series is optimized for low fan speeds. High-density copper fins paired with the 100mm thick fin stack move enough heat even at 800–1000 RPM — fan speeds that are effectively inaudible in a home office environment. A workstation running local LLM inference or AI image generation 24 hours a day cannot sustain 2000 RPM fan noise indefinitely. This radiator lets you drop fan speeds far enough that the system becomes background-quiet without compromising loop temperatures.

Compatible with standard 120mm fans in 4×120 or 2×240 configurations. Inlet and outlet ports are G1/4 threaded and positioned for straightforward mounting in most mid-tower and full-tower cases. Whether you are cooling a single RTX 4090 at sustained inference load or building a dual-3090 research workstation, the CR-RD480RC-TK100 is the radiator that handles continuous load reliably — day after day, month after month, without asking you to compromise on silence.
