Phenom 2 960t cooling

Is it normal for 960t stock cooler to make big noises while playing game, reading on speed fan is 40c while i'm not playing game fan speed around 2500 RPM but when i start game it goes to 47c and 5500 RPM very noisy.
In bios i have smart cooling on i did put new paste any advice what i can do.
Also other parts seems to work hot hdd 40-45c , 8600 GT 55c, psu is Chieftec 500w, case Chieftec CM-09B
Do i need more coolers or i just need to make some settings
