I have a dell inspiron 15 5559, i5 6200U CPU, 8gb RAM, 1 tera HDD and a Radeon R5 M335 Graphics. When I start to play any online game, the Radeon Graphics overheats to 90 Celsius Degrees in 15min or less (I got this information through the Overwatch). I already ran Dell's diagnostics which resulted in no problems in almost all of the components of the laptop (it just did not check the Radeon Graphics). Do you guys have any idea what could the cause of the Graphics overheating be? I hope you guys can help me. Thank you.
