What you need to know about keeping your computer cool.
Heat shortens the life of electronic components.
Almost all of the wattage drawn from your power supply when your computer is operating is converted to heat. The majority of modern processors are both figuratively and literally HOT, and require auxiliary cooling. If the cooling is inadequate, your CPU will begin to operate erratically, with undesirable results such as scrambled disk data. If the problem is not detected and corrected promptly, your expensive processor could fuse into a useless lump of sand. Fold and tie cables away from areas requiring free air circulation such as the vicinity of the CPU fan.
