In fact, water cooling will heat your room better! The PC will still be generating the same amount of heat, but you will be removing it from the machine and dumping it into the ambient air more efficiently.
My pc is in a not so big of a room and when i start playing like modern warfare 2 the room becomes a sauna.
The raison i don't buy an ac is because normally i would be living on my own, but the build has a delay. I want to buy an ac for my new home.
But it's going to be a very hot summer... i guess have to give up gaming in the summer. (of i have to swet it out )
hehe, i found a quick and dirty solution for my problem =)
I elevated the pc to window height and rotated it so that the hot air flows directly through the window and outside. (it is now 10 cm from the window ) Thereby preventing the room from quickly heating up.
My buddy used to do that with his Dell XPS that thing was like a Radiator heater. what he did was he got a piece of PVC piping and butted it up against the rear exhaust fan, then got a wall plug transformer thing 12v to run a fan. and stuck it on the end of the pipe, so the case fan would pump the hot air into the pipe and the pipe would run to the window, and the second fan would push the air outside. another thing he did later on was he got a window fan and piped the heat to the window fan. all in all that way you don't need to stick your computer up to the window and risk sun damage or a fall.
