Barrow Copper Radiator 40mm Thickness 12 Circulating Waterways, Suitable For 240/360/480mm Fans, Dabel-40a

The Barrow copper 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.
