3. CPU Hacks > 29. Check the Vents

Check the Vents

Add it all up—a screaming 7,200 or 10,000 RPM hard drive, a lightning fast CPU, stunning RAM throughput, blinding video performance, and a modest few watts of sound power—and you realize that puny little fan inside the power supply is not going to be able to suck out the extra BTUs of heat generated by all these hopped-up devices.

The operative words here are “suck out.” For some reason, PC chassis and power-supply engineers think that one little 2” fan stuffed into the corner of the power supply box is going to unload hundreds of BTUs of electronically induced heat and pick that heat out of all corners of the chassis. It’s just not so. Even a newer PC with a fan and duct work placed above the CPU to remove significant amounts of heat from the PC chassis is not cooling the system as effectively as possible.
