go into the bios and check the temperature

If you are using temperature monitor software from gigabyte or coretemp, etc, check the settings. Could be that it's getting close to a false limit, giving you a warning. You may just need to change a setting, or change to different software. Your cpu temps are excellent for a stock Intel heatsink. When I ran a 920, my idle temp was 60c. So don't waste money on another cooler yet. Also check the bios settings for temps. I've got mine set at 70c for shutdown. It's a safe setting. The 950 can run at 90c under load for short periods without damaging it.

btw if i using the mouse and the scroller the beeping is getting louder

Possibly a stuck key on the keyboard or faulty mouse since it beeps more when you use the scroll wheel

with the Settings seems to be OK!
but the source of beeping is the North Bridge
