We'll need a little more info than that. What are you doing to test temperatures? If you are going into the BIOS, then that is when the chip is at its coolest. If you're checking while running Prime 95 and using a program like Speedfan to monitor, then those are okay temps. But if it is an idle temperature, you're going to be having fried CPU for lunch one of these days. Download Speedfan if you haven't already, check your idle temps, and also download a program called CPU-z and post a screenshot of what it says. You might have a dreaded Palomino core, in which case it is not a good idea to overclock. Anyway, you should work on your cooling system. Make sure you have the proper amount of thermal grease on your CPU. Also, try to get the best airflow you can in your case. Upgrading to better fans will also help, as will a new heatsink on your CPU. Also, changing to a better case will also help. I reccomend the Cooler Master Centurion 5 for a cheap case. Looks good, has awesome airflow for its price, and has a lot of nice features. Before I got mine, I was getting 44C idle and 53C load. Now I get 34C idle and 42C load.
