Clean out your vents on the front and back of the computer case... and put the case back on... Most cases are designed for an airflow to pass over the RAM and Processor, from the front, out the back... make sure also that the fan is pulling air AWAY from the processor, not blowing it on the processor... make sure that the front vent is sucking in air, and the rear vent is blowing out air... it's best to have some case fans for proper air cooling....
