It seems in every watercooling setup I see people are putting thier rad near the bottom of the case and having intake fans blow thru it. Would there be any difference in cooling if you were to place the rad at the top of the case and having exhaust air being blown thru it?
The advantage to having it on the intake is to supply the radiator with the coolest air possible, but if your case normally runs at or close to ambient, there shouldn't be much difference.

Of course, if you get crazy with the new found quietness of the system, and start slowing down or removing fans, then that would effect the water temps, because there's still alot of other components that aren't enjoying that cooling water, like the drives, the power mosfets on the mobo, cards etc....

Have a good'n!
or you can be like me and put the rad at the top and push air through it from the outside and thin at the bottom of the case have the fans sucking the hot air outside.
