Hey,I am using i5 4460 and have stock intel cooling solution and using preapplied.It's been 1 year since I started using this and I have my hands on arctic silver 5 for a long time but havent used cause I am satisfied with temperatures.Atm at idle I can get 25-28 and 45-55 to 60 MAX(using in wow in a place with LOADS of players-over 50-) .I am also using intel HD so I don't know how heavy that's on my pc,was thinking of getting a gtx 970.So,after 1 year should I change the pre-applied with arctic silver 5 when my temperatures are that good or no?
