I have an i7 9700k coupled to a corsair h100x.
I also put in a gigabyte windforce 2080 ti (non-oc version). Made sure of clearance on the gfx by putting in an evga 650w sfx power supply.
Radiator is mounted to the front (with fans as intake) then I have one fan in the bottom as an intake and one at the back as an exhaust.
CPU tops out at 60 when gaming (at most) and the GPU hovers between 75 and 80. Not the best temps maybe, but well within tolerance.
Also found a place that will make a mesh top for the case for cheap, which helps reduce the temps more
