try getting an aftermarket CPU cooler that can fit in your PC case and your motherboard. They work better than the stock CPU coolers and are quieter too. Cooler Master and Zalman make great CPU coolers. Hope this helps!

It will help to know what sort of climate region you live in. I am concerned that the 8350 may be a little too much for that case. I am going to assume that your case fans are set as such. 1 Intake fan up front, 1 exhaust in the rear and then where is your third fan located?

both intake fans at the front and rear while exhaust is at the side.And The Cpu is kept in an open space temperature is roughly 31 degrees .Has it got anything to do with power supply??

The way you have your fans setup is not optimal at all my friend. You want one of your 120mm fanspulling air in through the front of the case, one of your 120mm fans at the rear blowing air out of the case and the best thing you can do with the third is modify the grill on the top of your case to hold the last fan blowing air up and out of the case. If possible get a fourth fan to put up front as a secondary intake.

Also you need to make sure the person who last worked on your PC installed the heatsink right and applied thermal paste properly. Carefully unplug your cpu fan from the CPU fan slot and then undo the retention lever securing the heatsink. Unlatch the retention arm and remove the heatsink from the board. If you have too much thermal paste it may be necessary to wiggle it. Once your heatsink is removed you are going to clean all of the thermal paste off with 70% or higher isopropyl alcohol. You can use a business or debit card to scrape the bulk of it off and then a microfiber cloth or cotton balls to clean it the rest of the way. You want to keep cleaning until your cloth or cotton balls are no longer turning dark. Now with the CPU still in its socket repeat this process. Though isopropyl alcohol evaporates quickly and posses no significant threat to an unpowered motherboard it is still prudent and wise to apply only enough to your cloth or cotton balls to remove the thermal paste. Again clean your CPU until your clothe/balls are no longer turn dark. Then you are going to run a line of thermal paste up the center of the processor just slightly thicker than a stick of spaghetti. Then reinstall the heatsink in the reverse order you took it off.
