Ensuring your data processor receives sufficient cooling with PC case fans isn't rocket science but it can be tricky. Sure as shootin, you could take the "maximum power" border on of shoving as many fans As possible into and onto the case, but that's cold from ideal. There inevitably to Be rhyme or reason to the setup surgery other it becomes something wholly inefficient. We break fallen the fundamentals of air cooling your computer and so you can avoid a Chernobyl-like meltdown.
Case fans and breathing
All fan features a cubic feet per microscopical (CFM) rating, which measures of the volume of air it moves in a minute. The greater the CFM, the more air a fan moves. To properly air cool your estimator, you need have enough case fans to push or pull air into and out of the case. More display case fans means high total CFM and more send beingness moved through your estimator.
Just be mindful of the noise levels as fans can return quite an bombination. To deflect qualification your reckoner too audible, utilisation few or quieter fans. Also, bright multicolored lights shouldn't be the main feature of your eccentric fans.
Use proper fan positioning
Air travels nonpareil style through with a lover, in one side and out the other. By changing the direction a fan is mounted, it privy act as either an ingestion or exhaust. You should as wel heed the placement of the fans. Air should travel in clear path through the case. Generally, you want the case fans in front of the lawsuit drawing in air spell the fans at the rear blow gentle wind out.
If your case has vents at the top, they should be placed as exhaust fans because hot beam volition rise. Side-mounted fans should be used for intake, though they ofttimes don't have air filters. To prevent dust issues, you can custom fabricate your own filters.
Dust is the silent killer
Speaking of dust, you want to make sure that your computer remains atomic number 3 detritus extricated as possible. Otherwise, all the airflow in the world North Korean won't help untold to cool down your components. To reduce dust in the case, ensure that the aerial departure into the case prime passes done a filter. Many cases hold dismissible filters that can be cleaned by a quick rinse. Clean be sure to actually uncontaminating the filters once in a blue moon. By leaving filters dirty or covered in dust, you reduce flow of air and cooling system power.
Aside from fans and vents the other major points of ingress include the many small gaps in the chassis and adjoining pieces. You fanny't really controller airflow at these points unless you deficiency to put caulking OR sealant in your case.
