Billet Labs' fanless PC struggles with CPU temps despite passive cooling

A London-based PC cooling firm, Billet Labs, has developed a custom-built, entirely passive water-cooled gaming PC. This innovative build utilizes a convection chimney effect powered by triple-stacked radiators to dissipate heat without any fans. While the system successfully prevented the RTX 5080 GPU from thermal throttling, the AMD Ryzen 7 9800X3D CPU experienced some throttling, reaching temperatures of 95°C or higher under heavy load.
