Bykski Extreme-Performance Multi-Block 4,200W Heat Dissipation Radiator, 9x120mm Support (CR-RD1080RC-TK100)

The Bykski CR-RD1080RC-TK100 Extreme-performance external radiator delivers extreme heat dissipation, capable of removing up to 4,200 watts of heat for custom liquid cooling loops. With a large fin surface area and optimized core density, it efficiently handles high thermal loads from CPUs and GPUs, helping maintain lower coolant temperatures for improved stability and potential overclocking headroom.

A high-flow design supports strong coolant throughput for multi-block systems. The radiator features standard G1/4” ports and can be integrated into parallel or serial loop configurations. For complex setups with multiple components, appropriate fittings or manifolds may be required depending on your layout.
