I am running at 1440p. Be warned if you buy a monitor like that. You will never want go back to HD again.
But it sucks how much more performance it requires.
I have the NZXT H440. It it not known for it's airflow. The design reduces the amount of air that can be pushed in and out. (looked beautiful though and is optimized for silence)
So what i have is 3 Corsair AF140 performance case fans (which are great), and i use corsair H60 2014 edition liquid cooler on the CPU.
