Hi! I have an Asus ROG g771jw with an i7 4720hq and gtx 860 4gb. The problem is its temperature reaches even 70c idle and 90c on load if using without throttlestop but the graphics card it's ok, like its most 80c. The laptop has no ventilation underneath, no airflow, just a one-piece bottom. What could be the cause of overheating??
