Mount storage drives in the designated 3.5" or 2.5" bays and install expansion cards in the seven PCI slots. Place fans or radiators in the available top, side, rear and PSU-compartment positions according to your cooling needs. Use the front-panel knobs to adjust fan speeds and the light button to cycle ARGB modes. For full functionality of the digital temperature display, download and install the driver from the manufacturer's website.

Recommendations

To maintain airflow and component temperatures, use a balanced combination of intake and exhaust fans and clean the removable dust filters regularly. When planning water-cooling, verify radiator thickness and clearance relative to other components. Use the front-panel fan speed knobs to fine-tune cooling under different loads and install the driver from Darkflash for full control of the temperature display and ARGB features.
