I am using an i7 2600K processor on the P8P67pro with w/stock CPU cooler. There are no over locks or any tweaks in the processor. The performance settings are in simple BIOS. The GPU that is being used is Asus GTX580.Also I have a compact Silverstone HTPC cabinet. Also present are two cabinet fans. Now the problem is that while running some high profile games like FarCry2 and BFBC2 and by keeping all maximum settings and also starting with the real temperature the temperature suddenly sores. So can anyone give me a reason why such thing takes place? Please do reply to me.
