I recently just upgraded from a GTX 960 to a used RTX 2080 and i quickly found out it's a space heater that just so happens to run graphics really well.
My room dosent have air conditioning and there isn't much air moving around so i did the only sane thing i could think of and that was to make a magnetic duct for the side of my lian li 011 dynamic and toss the hot air overboard.
It's been working well ever since i haven't died of a heat stroke.
I made the duct from a couple peices of illustration board, an aluminum duct and a 140mm. I since then upgraded the 140mm to a high velocity 120mm.
Its been working really nice and ngl it dosent look half bad. It looks a bit more beefy cause of a massive hose sticking of the side of it.
