I don't understand your question. The only vent in right side while not directly beside PSU supplies PSU. There is a 90mm vent in back into PSu compartment behind motherboard. Another 80mm vent in back in motherboard compartment and 2x 120mm vents in front that I'm not sure if they are both into motherboard compartment or partially into PSU compartment. Is there a 120mm vent in left side panel into motherboard compartment?
