Got tired of the pc heating the room, so i solved it sensibly.. from r/pcmasterrace
In what they describe as “just a proof of concept”, one Redditor has gone further than your average custom looper to help keep their game room cool, by routing the liquid cooling in their gaming PC outside to a radiator sat in the cold winter air.
The setup involves slapping a Bykski water block on their Nvidia RTX 4070 Ti and direct-die cooling on the Intel Core Ultra 7 270K Plus using a Thermal Grizzly 1851 Mycro Pro water block, after de-lidding the CPU, of course.
The two blocks are hooked up to each other, and the custom loop can feed water through a radiator outside through holes in the wall when needed.

Part of the reason for doing all this, the Redditor claims, is that their room gets warm when they game:
“My room gets warm when I game and it’s -4 outside. Free cooling right? The catch is if the water going into the PC gets too cold you get condensation on the parts, and water dripping on a 4070 Ti Super is not the vibe. So the whole thing is built around keeping the water cold, but not too cold.”
“The pc loop runs like normal. When it needs extra cooling, the second pump sends some of the water out to the rad outside and back in.
“A Python script starts on startup and it connects to the Arduino, takes over from the Arduino’s own auto mode, and it connects to HWi and Fancontrol so i get total control over the dynamics.”

Yep, that’s right; the loop also involves a secondary computer system managing everything. Part of the calculations the Arduino boards handle involves keeping temperatures above the “dew point”, ie, above the point at which a difference in temps might make condensation form on the electronics. Because, y’know, that thing about water and electricity not mixing.
Although part of this was to keep the gaming room cool, I’m sure another part was pushing these components for performance. And on this front, there are some great results, including keeping the GPU running around 48 °C under load and the CPU at 52 °C under load. While playing CS2, the GPU stays at 34 °C and the CPU stays between 45–50 °C.
Given this is just a “proof of concept”, there’s more to be achieved, and the Redditor says: “I’m coming for that number two spot in Steel Nomad for 4070 Ti Super.” In other words, they’re trying to beat out some top records for that 3DMark benchmark. Let’s hope for a nice and chilly winter, then.
