In the summer back in the day, I had my desktop pc standing somewhat tilted in the window, with the window in a locked position so it didn’t fall out. I had taken off the chassis, with a floor fan pointed at it. Only then would I get ~60 FPS in CSGO. I had a tiny bedroom in a shared house with other poor students, so it got way hotter in my room than outside

Me when i had to game on a Dell laptop with terrible cooling

So I have my 750W PC under my desk which is closed on the right and left side and half of the back (where my case is). My legs will be cooking all summer.
