What’s next? A PC in a freezer? DIY enthusiast thinks it makes sense to pair an power-guzzling AC with a PC

• Ultra-low GPU temps sound impressive until you consider the power bill
• Cooling a GPU with an AC unit may work, but the size and risks make it impractical
• A 12,000 BTU AC for GPU cooling: it works, but at what cost?

A Chinese techtuber has integrated a 12,000 BTU air conditioning unit into the liquid cooling system of the RTX 4090 and an Intel Core i9-13900K processor.

ESC’s setup replaces a conventional PC-mounted radiator with a household air conditioning unit. The modified Xiaomi KFR-35GW air conditioner serves as the primary cooler component while the system directs chilled liquid through a loop connected to the PC.
