Lately I have noticed that my computer froze when playing games and notice that the temp of my CPU was getting a little too hot. So I reapplied new thermal paste today and the temps went down a bit. But I'm not certain what temps are normal for my CPU. When I'm just surfing the internet and stuff my temps are around 50-56 degrees celsius. When playing BF3 on Ultra settings the temp is around 85-88 and running REAPER (a DAW, a music production program) with several audio plugins running the temp is around 78-80 degrees. Are these temps normal or not? I do have a custom fan but I don't know which one. It's not stock fan atleast. All fans on my computer are clean. Note that when playing games my computer does not seem try freeze anymore. Played BF3 for like 1h and 15 minutes and went nice and smooth.
