The YouTube channel TrashBench has successfully repurposed a used 4kW AC radiator into a custom cooling solution for high-end PC hardware. The experimental setup was tested on an and an , though the latter lacked headroom.
Testing revealed that the RTX 3080 GPU temperatures dropped by 37°C at stock speeds. The radiator allowed the power limit to reach 459W, well above the 320W-350W stock range, while pushing the core clock to 2,130MHz despite an incredibly noisy stock pump.
When an was added to the loop, it reached a 230W power limit with temperatures falling from 74.8°C to 71.7°C. This project demonstrates the extreme thermal capacity of industrial AC hardware when applied to modern enthusiast components.
