u/Motor_Attention1865 on Reddit didn't like how his PC added extra heat to his room in the winter, so he went the extra mile to dump the heat outside in a fashion similar to mini-split air conditioners. The external cooling system is controlled by an Arduino Mega that the PC communicates with when it needs extra cooling. The system opens a three-way valve to route coolant outside and prevents condensation by keeping the coolant temperature above the dew point.
Our intrepid modder's room has heated floors, and the PC was dumping too much heat under the table where his PC sits, even in 25 °F (-4 °C) weather. He grew tired of manually opening a window to regulate the temperature in his space, so he put in much more effort to create a split cooling system that puts another radiator outside in the below-freezing temperatures, cooling down the PC significantly.
Motor_Attention1865's build itself is impressive enough, with a delidded Core Ultra 7 270K Plus cooled by a Thermal Grizzly 1851 Mycro Pro direct-die water block with Thermal Grizzly Conductonaut Extreme liquid compound. Not only is his RTX 4070 Ti Super also watercooled with a Bykski water block, but the 2x24GB DDR5-8400 G.Skill RAM is also watercooled using Bykski heat spreaders with an IceManCooler two-channel water block. The cooling system within the PC has two radiators: a 120mm in the back and a 360mm in the front, all fed by an EK Kinetic D5 pump-reservoir.
