Redditor runs PC cooling loop outside of their house to keep it cool in one of the bravest yet unnecessary mods I’ve ever seen
A Reddit user has routed their gaming PC’s liquid-cooling loop through a radiator outside, using winter air to cool the system and reduce heat in their gaming room. The unusual setup matters because it can improve cooling performance, but brings a risk of condensation if the water gets colder than the room’s dew point.
The PC uses water blocks on an Nvidia RTX 4070 Ti Super and a de-lidded Intel Core Ultra 7 270K Plus, with a second pump sending water to the outdoor radiator when extra cooling is needed. An Arduino and Python script monitor and control the system to keep temperatures above the dew point. Under load, the GPU runs at about 48°C and the CPU at 52°C; during Counter-Strike 2, they reach 34°C and 45–50°C respectively.
In short
- A custom loop sends PC coolant through an outdoor radiator.
- Arduino and Python controls help prevent condensation.
- Under load, the GPU reaches 48°C and the CPU 52°C.
