If you are going to go with an air cooled solution I my self use an open case since of the GPUs but the CPU is water-cooled.
Your temps are high because you're using the wrong GPUs for a thresome setup. The recommendation in this forum since years are original OEM-GPUs with radial fans like the GeForce 1080GTX Founders Edition. The axial fans on your GPUs are blowing against each other and are pretty much ineffective. Using radial fans, a closed case for better airflow and some additional fans will bring down temperatures into the 50-60° range.
