Not much you can do apart from get a large cooling fan and direct it at the case. --- Just want to add one other point to Barry's excellent reply... Also, we need to be careful where we keep our CPU as many of the newer storage cabinets don't provide a lot of ventilation and the CPU needs room to "breathe" and to allow the fans to bring air in. If you stack papers or books all around the CPU you could be blocking the air intake which could result in overheating. Joan
