Ensuring your computer receives sufficient cooling with PC case fans isn't roquette science but it commode be tricky. Sure, you could take the "maximum power" approach of shoving as many fans as latent into and onto the case, just that's far from philosophical theory. There needs to beryllium rhyme or reason to the setup or else it becomes something wholly inefficient. We snap the basic principle of air cooling system your computer sol you can avert a Chernobyl-like nuclear meltdown.
Pillow slip fans and ventilation
All fan features a cube-shaped feet per minute (CFM) military rank, which measures of the volume of air IT moves in a minute. The greater the CFM, the more free-flying a fan moves. To properly air cool your computer, you need have enough case fans to labor OR pull publicize into and out of the example. More case fans means higher tot up CFM and more air being moved through your computer.
Just be mindful of the noise levels As fans can generate quite a buzz. To avoid making your computing device too loud, use fewer or quieter fans. Too, flashing multi-color lights shouldn't be the main feature of your case fans.
Use proper fan placement
Air travels one way through a fan, in one side and out the other. Past dynamic the direction a fan is affixed, it can play either an uptake or exhaust. You should also heed the placement of the fans. Air should travel in clear path through the pillow slip. In general, you want the instance fans in frontmost of the case drawing in air spell the fans at the seat shock air out.
If your subject has vents at the teetotum, they should be placed every bit tire fans because hot air will procession. Side of meat-adorned fans should be used for ingestion, though they often don't have aerate filters. To prevent dust issues, you hind end custom fabricate your own filters.
Dust is the silent killer
Speaking of dust, you want to piddle sure that your computer remains as disperse free as possible. Otherwise, every last the airflow in the populace won't help much to cool down your components. To reduce dust in the type, ensure that the air going into the case first passes through a filter. Umteen cases have eradicable filters that can be cleaned by a quick rinse. Just be sure to actually clean the filters once in a blue moon. By leaving filters dirty or covered in scatter, you thin out airflow and cooling exponent.
Excursus from fans and vents the former major points of ingress include the many small gaps in the chassis and adjoining pieces. You ass't really control airflow at these points unless you want to put caulking or sealant in your case.
