YouTuber builds PC water-cooling loop from scrapped 4kW air-conditioner radiator
Hardware modder TrashBench repurposed an old 4-kW outdoor AC radiator-fan-pump unit into a custom water-cooling loop for a PC, 3D-printing mounts for cold plates and reservoirs along the way. Testing showed an RTX 5060 dropped from 52°C to 33°C under the setup, and an overclock pushing boost clocks from 2902 MHz to 3300 MHz yielded only a 3% FPS gain despite the 14% clock increase.
