For this build, I wanted to have excellent cooling in a medium sized form factor. My old setup included the Cooler Master - Masterbox Lite 5 RGB which looked great but had terrible air flow. Also, I was using the Cooler Master Hyper 212 Evo air cooler which seemed to work well but took on extra heat from the Asus Strix 1080 GPU. The old case / CPU combo was causing my CPU to run at 70-71°C under load at the stock 4.0 GHz.
For the new setup, I decided on the Fractal design Meshify C for it's great airflow and the NZXT Kraken X62 AIO cooling system. Obviously, the NZXT is a little bit large for this case and overall setup but again, the goal is excellent cooling. Two additional exhaust fans were added to the to of the case to help pull out all the heat from the Strix GPU. I did have to use the Dremel on the front shroud of the case to get the 140mm NZXT fans to fit. With a little work I was able to get the large cooling system to mount and still maintain the stock look of the Meshify case.
The results of the new cooling system are, in my opinion, pretty impressive. My CPU now runs at 30-35°C under load while overclocked at 4.5 GHz. I would like to overclock a little more after stress testing. The GPU also runs a few °C cooler thanks to the extra exhaust fans in the top of the case.
