I have an AIO 360 rad and i had the rad as exhaust for some time and the temps on my 2700x would reach about 55c on stock, which looked kinda high as my room is cold about 18-20c on average and flipping the fans to intake lowered my temps to 45 at max load (stock) so i'm happy, its actually boosts to 4,050 most of the time.
Just flip the fans to intake and make sure you have other fans set as exhaust.
Cheers.
