Bykski 30mm Red Copper Radiator, RC Series High-performance Heat Dissipation, Black/White 120/240/360/480 Thickness For 12cm Fan Cooler, CR-RDRC-TN-V2

The Bykski copper 120mm radiator is the heat-rejection backbone of any custom water cooling loop. High-density fin stacks and full copper construction maximize thermal transfer to the air while keeping flow restriction low enough for quiet, low-speed fans.

AI inference is a continuous heat source — not a gaming spike. A properly sized radiator keeps loop temperatures stable across multi-hour LLM sessions, protecting VRAM and GPU die from the slow thermal creep that causes throttling. Sized for single-GPU or multi-GPU configurations depending on fan mount count.

Material: copper core, aluminum or copper header tanks. Fittings: G1/4 ports. Ships worldwide.
