I have an i5 3570k processor, a HD 7950 AMD Radeon GPU and a Arctic Freezer 7 CPU Fan, in place a cooler master case. When I play high-end games such as Crysis 3 or Tomb Raider (New One) I find that the temperature escalates to up to 70-90 degrees and in some cases; the computer shuts it self off in order to prevent any damage from occuring. I though that the normal stock fans would handle this; so why not the Arctic Freeze 7? By the way this build is fairly new, and I can't see any dust collecting anywhere. Any tips? I've played around with the GPU fan but that doesn't help.. :/
