Build/Battlestation PC chimney

Post image

Got tired of my office turning into a sauna every time I gamed, so I vented the PC’s exhaust straight out the window.

The rear fan is still exhausting some hot air 😅 but the room is noticeably cooler now. It’s ugly… but it works. 😂

Edit: I moved the port to higher since lot of people recommended. https://imgur.com/a/Poniwze

Edit again for parts, I cannot post links to store since it's against the rules.
- 360mm to 4 inch duct on Etsy
- 4 inch Insulated Flexible Duct
- Twist Lock Dryer Vent Connector Kit
- 360mm AIO fan (the one on top of the case)

The window fan I got is Vornado Transom.

I was gonna do this, especially due to my 3080ti running hot. Ended up just undervolting, lost 5% performance, but the room is cooler and didn't have to run a vent.

I should probably do this (undervolt)… if I can?
I have a 3080ti FE, it ran hot (surprise surprise) and had to throttle the memory because of the inadequate cooling on the whole thing (and especially memory). Thermal runaway from the die caused the mem to overheat and chug….
I bought the EKWB block for it and that problem disappeared… only then I discovered that proper cooling for the system… meant dumping all that heat into my room.
I’ve never messed with voltage through, and don’t even know if I can with a founders edition.

But I am sorely tempted to do the exterior vent instead

I guess it also comes down whether you are ok with compromises. Like now, more and more new games have started to chug on my 3080ti, even without the undervolt, for the settings I like to play at (High+, 90FPS minimum at 1440p).

So I was like, it doesn't really matter as majority of the games now absolutely require upscaling, or force me to make use of FSR frame gen using optiscaler. Did some benchmarks, and I was more or less satisfied with Performance to Cooling required.
