does heat mess up the processor?

[hathetran]

hey guys,

ive been noticing my phone has been locking up recently...for instance ill go text message tab put my phone on standby and when i wake it up a little bit later its frozen and i have to press the end key to unfreeze it..is anyone experiencing this? i dont think its a software problem cause ive hard reset my phone and it never happened when i upgraded to the 6.5 stock rom..im thinking its happening cause i left my phone in the car once and it got too hot..which in turn mess up the processor/transistors somehow?
