My CPU wasnt running up to speed recently, all 6 cores were at 800MHz. I checked out my BiOS and I changed it so all core are running at 2.1GHz. I can clock them up to 2.7GHz a core, like they should be, but im afraid my CPU will overheat. I have a stock cpu cooler. Any suggestions on CPU coolers? Im only 14 and I dont have a job, on a strict budget. So please make them as CHEAP as possible.
