You know what I’ve never thought of one while using a gaming PC? “Man, I really hope my RAM sticks aren’t overheating.” I mean, I’m sure if you pushed a system to its absolute limit and didn’t have proper airflow within the case, maybe RAM can malfunction in a hot environment. However, if I’m diagnosing a system issue, thinking of how hot the RAM is getting is pretty down there in my list of things to check.
