What case is your system in and what CPU cooler are you using?

Air flow and room temperature is very important with cooling.

Im just using the default cpu cooler.there are no additional fans inside the casing

you need additional fans.. atleast 1 exhaust, and if possible two intake fans. That will give you a positive pressure inside the case and keep out dust.
