This B-1080-SPD-CEC-X external thermal exchange unit is a high-capacity liquid cooling solution optimized for up to 4 discrete GPUs. Designed as a standalone radiator/pump/reservoir assembly, it offloads heat from dense multi-GPU loops, enabling lower operating temperatures, quieter acoustics, and improved stability under sustained compute workloads. By pairing this unit with your internal water blocks, you can significantly reduce coolant temperatures and help extend component lifespan.

A high-flow internal plumbing layout supports multi-block loops with minimal restriction. The unit can be integrated into parallel or serial loop designs. In multi-block setups, appropriate manifolds or bridges may be required depending on your GPU block configuration and case routing.
