Yes, this is the correct setup for a CLC provided you have at least average airflow in your case. With even moderate airflow, in case temps should only be several degrees higher than ambient and will not affect your CPU temps to a great extent.
However, using the rad fans as intakes essentially turns the PC into a convection oven, and the temps of all of your other components will suffer. You would essentially be blowing warm air into the case at a far higher rate than it can be easily exhausted, so you would see rises most notably in GPU and VRM temps. The longer you use the PC, the higher in case temps would be, causing component temps to continually rise.
So, while you can get a couple of degrees better on CPU temps under load by running the fans as intake, it is an incredibly myopic approach to cooling when other components are air cooled. Your temps will be far better as a whole with the rad fans as exhaust - your GPU will thank you for it.
And on the subject of fans.....you do realize that you can buy a Swiftech H240-X2 for less than what you would wind up spending in an H115i and a pair of decent fans.......Edited by ciarlatano - 6/3/16 at 9:51am
