I'm running an M14x R1 i5 2.4 Ghz GT 555m 1.5 gb I reapplied thermal paste and air duster'd everything, my temps while playing games like Shadow of Mordor and Dying Light (almost lowest settings on both) run between 55C to 68C depending on ambient temperature. I'm just wanting to get some opinions on whether or not my temps are already to high for overclocking before I flash a custom bios and mess with volt modding. I've never attempted overclocking this laptop (or any other laptop) before, but as my GTX 960 crapped out I'm forced to game on the M14.
