I'm running on a laptop (lenovo y470) specifically. I have only an i3 and nvidia 550m. I usually play games fine, and my CPU rarely goes over 75. However, I get randoms cpu temp spikes at menus. For example, I run blacklight retribution great, but sometimes at the menu my cpu temp spikes to 85 and it throttles down. Why is this and is there any way to stop it from happening? Also could I upgrade my processor if that is the problem?
