Heating Problem!!!

Hi I’m using mx4 32gb I version but I installed last beta version 5.6.5.10a. But there is a problem. Phone was so hot that I can’t touch the phone after 5-7 minute gaming. I think this is not normal. Is the heating because of beta version? I read a few article about mtk6595 and its heating problem. But it was so hot. Is there your phone same problem? Or have anyone any solution? I liked flyme 5.x.x.x version but both there are not only international version but also this heating problem. Should I return the latest stable international version? Thanks. Have a nice day
