This is my daily driven PC/Sim Racer that I have been tinkering with for the past 2 years. I have been doing everything I can to not go with a custom/open loop setup. I am currently running my 4790K at 4.9 GHz on all cores. I delidded the CPU with Thermal Grizzly Conductonaut. The CPU doesn't see any temps > 58°C.
Most of these components were in a black InWin 303. After some time and saving, I decided to do a full Corsair 570X / RGB LL build. I went with the mirror black finish of the 570X due to it's stealth look when it is off. Although it's a GIANT fingerprint/dust/smudge magnet, I think all tempered glass cases should come in a mirror finish. The mirror black finish also features an integrated vertical mount for your GPU. It also comes with a closed up PSU shroud (unlike the regular black and white variants of the 570X).
After vertical mounting the GPU, I noticed that the GPU was bottlenecking/choking for air due to it sitting so close to the side thermal glass panel. It was peaking at 85°C and it was greatly effecting the performance of the card. I then decided to go with the NZXT G12 bracket mated to an NZXT X52 to match my CPU AIO. Now it peaks in the mid to high 50's (59°C is the highest I've seen it hit).
I'll eventually swap out my MOBO, CPU, and RAM when something newer/exciting drops from either team red or blue. But until then... my current build will suffice.
******UPDATE 01/08/2019 *********
I got my hands on an Intel i7 8700K, GIGABYTE AORUS Elite Z390, and 16 GB of GEIL SUPER LUCE @ 3000 MHz over the 2018 holidays. Able to easily achieve a stable 5.0 GHz @ 1.30V without de-lidding the CPU. I'm very curious to see what kind of clock's/temp's i'd see after de-lidding with Thermal Grizzly Conductonaut.
