A cool breeze for PCs
Keeping your computer cool is vital for its health. If it overheats, it risks frying its circuitry, and once that's happened, you'll have to purchase expensive new components to fix it. There are many ways to keep your computer cool, and the simplest of these is to install fans. An exhaust fan is essential, as its presence can decrease computer temperatures by 10 degrees Celsius. If this isn't enough to keep your computer cool, an intake fan can reduce temperatures even more.
Instructions
1. Turn off your computer and unplug it. It is essential that the PC have no power flow, as the slightest shock can damage components and cause injury.
2. Open the computer case. Every case is different. Some will require you to unscrew the siding while others will have a snap mechanism.
3. Screw the exhaust fan onto the rear fan mount on the inside of your computer case. Every case is different, but the mount can generally be found near your input/output hub where you connect your mouse and keyboard. Before screwing the fan into place, make sure that the exhaust is going in the right direction. Many models will have arrows to direct you. You want the airflow leaving the computer case.
4. Plug the fan into a power source. Some models can be connected directly to your computer supply unit, which is the box at the top of your computer with 6-pin wires hanging out of it. Attach one of these wires to your fan. It may also plug directly into your motherboard. If that's the case, look for a 3-pin connector on your motherboard. There should be one located near the fan mount.
5. Screw the intake fan into the intake mount if you're installing one. The intake mount is generally located on one of your case's side panels, quite possibly the one you removed to access your computer's inner workings. As with the exhaust fan, be certain to have it blowing in the right direction. Once it's mounted, plug it into your computer supply unit.
6. Close you computer case, plug the computer back in and turn it on. Put your hand beside the fans and check again that they're blowing in the right direction. If not, turn off the computer, reopen the case, and adjust them as necessary.
