Hello to all
I would like to install a water cooling system in the computer. From what I've seen illustrated for the closed loops , the radiator and fans can be mounted anywhere you want, as long as the case has a provision, and the parts reach. So far, everything that I've read and understood indicate to have the fans pull the hot radiator air back inside the case, instead of blowing it directly out. I don't get that part of the concept. I went back to the Corsair website to look at their installation instructions, and seen it there again. I know in an automobile the hot radiator air is blown back into the engine compartment because that's the direction the air flows, given the forward motion of the vehicle. I just don't understand why blow hot (or warmed) air back into the inside of the case, that you work so hard to cool in the first place. Please help me to understand.
Thanks

Because the coldest air is going through the radiator, it cools the the CPU the best. The greater the difference in temperature between the radiator coolant the the air going through the radiator, the greater the capacity for heat exchange. Although some heat is introduced inside the case, it's not that much. The cpu is like the head of a match. It's extremely hot when are right next to it, but it doesn't add significant heat to the room. Some tests I've seen didn't show much difference whether the radiator was an intake or an exhaust.
