280mm Radiator Buying Guide for High-TDP CPUs

I have completed a comprehensive analysis of the 280mm radiator market, focusing on product trends, performance benchmarks, and B2B sourcing insights for 2026. The 280mm format is currently the "sweet spot" for PC cooling, offering nearly 90% of the surface area of a 360mm radiator while providing a superior noise-to-performance ratio due to its larger 140mm fans.

The global AIO cooling market is projected to reach $1.67 billion by 2033, with 280mm units maintaining a strong niche for high-TDP CPUs (up to 200W). Key trends include the integration of LCD screens, a shift toward 38mm-thick radiators, and a heavy manufacturing concentration in Shenzhen, China, where wholesale prices range from $45 to $65.

The full report below details technical benchmarks, consumer sentiment, and strategic sourcing recommendations.
