Forever Oleg :
1) Close the f*cking window.
2) Download HWMonitor and check the temperatures of your parts b/c it shouldn't be overheating that bad.
3) What ARE the components of your PC? You can check that with HWInfo or Speccy.
4) Open the PC and clean it of dust.
5) Do not do anything yet until you answer the questions 2 and 3 for me.
You think i'm that kind of technology blind? LoL... I'm keeping an eye on temps every single motherf*cking time i play video games. The hotest the cpu got was 63C and it'll go down eventually. GTX 970 is hot, i know, AMD FX 8320 OC to 4.5GHz with CORSAIR HYDRO SERIES H80i GT... Did a dust cleaning before, just attached a dust filter on the rear case fan... That'll solve. Lowest temps the CPU could get is 26C on idle, loading isn't go above max safe temps and monitoring thermal margins with amd overdrive. So did i answer your question?
