  "account": "A Redditor has pushed the limits of PC cooling by creating an innovative setup that routes their gaming PC's liquid cooling system outside to a radiator, in what they describe as a proof of concept. The Redditor, frustrated with their PC heating up their room, decided to tackle the issue head-on.\n\nThe setup involves attaching the Bykski water block to their Nvidia RTX 4070 Ti graphics card and the Thermal Grizzly 1851 Mycro Pro water block to their Intel Core Ultra 7 270K Plus CPU, after delidding the CPU. These two blocks are connected, allowing the custom loop to feed water through a radiator outside via holes in the wall when necessary.\n\nThe main challenge for this setup is preventing condensation on the components when the water gets too cold. To address this, the system is designed to keep the water temperature above the dew point, ensuring no risk of water droplets forming on the electronics and causing damage.\n\nThe PC loop operates like a typical system, with a secondary computer system managing everything when extra cooling is needed. This secondary system connects to an Arduino and HWi software, allowing for complete control over the cooling dynamics. The Arduino handles temperature calculations, ensuring that the temperatures remain above the dew point and preventing any water condensation issues.\n\nThe results of this unique setup have been impressive. Under load, the GPU runs around 48°C and the CPU runs between 45-50°C, keeping the gaming room cool and allowing the Redditor to push their components for optimal performance. With this being just a proof of concept, the Redditor aims to reach new heights and break some impressive records in the 3DMark Steel Nomad benchmark for the Nvidia RTX 4070 Ti Super. A chilly winter may just be the key to achieving these goals.",
