I have three big case fans, the CPU fan and a pair of small fans on the front. It has had this problem since I built it, but it usually does it one or twice and hten settles down, but when it gets really here it gets worse. It doesnt help that I have a 6 room house and no AC. Its about 95 degrees and over 70 percent humidity. anyway I guess I will use the laptop to post until it cools off some.
