I've got the same CPU. Mine always runs close to 35 C.
The trick: At the urging of my computer tech, for years now, I leave the cover off the box and have an external fan blowing over the motherboard! It fan was bought at Bed/Bat and Beyond for $12. It does a gabulous job. My MB, too, runs VERY cool----29 C.
And, the computer stays extremely clean. When closed it used to accumulate tons of dust and dirt.
