And sure in your computer receives sufficient cooling with PC case funds isn't rocket science, but
it can be tricky.
Sure, you could take the maximum power approach of shoving as many fans as possible into and onto the
case, but that's far from the ideal.
There needs to be rhyme or reason to the setup, or else it becomes something wholly inefficient.
We break down the fundamentals of air cooling your computer so you can avoid a meltdown.
Every fan features a cubic feet per minute or CFM rating, which measures the volume of air.
It moves in a minute.
The greater the CFM, the more air a fan moves to properly air.
Cool your computer.
You need to have enough case fans to push or pull air into one or two of the case.
More case fans mean higher total CFM and more air being moved to your computer.
Just be mindful of the noise level.
Fans can generate quite a buzz to avoid making your computer too loud.
Use fewer or quieter fans also, flashing multicolor lights shouldn't be the main feature of your case
funds.
Air travels one way to a fan in one side and out of the other by changing the direction.
If one is mounted, it can act as either an intake or exhaust.
You should also heed the placement of the fans.
Air should travel in a clear path through the keys.
Generally you want the keys funds in front of the keys drawing in air while the fans are the rear blue
air out.
If your case has vents at the top, they should be placed as exhaust fans because hot air will rise.
Side mounted fans should be used for intake, though they often don't have air filters to prevent dust
issues, you can custom fabricate your own filters.
Speaking of dust, you want to make sure that your computer remains as dust free as possible.
Otherwise, all the airflow in the world won't help much to cool down your components to reduce dust
in the case and show that the air going into the case first passes through a filter.
Many cases have removable filters by leaving filters dirty or covered in dust, you reduce airflow and
cooling power aside from fan and vents.
The other major points of ingress include the many small gaps in the chassis and adjoining pieces.
You can't really control airflow at these points unless you want to put cocaine or sealant into your
keys.
Optimal air pressure with a computer case is one of the most discussed and debated topics in computer
cooling.
In simple terms, a computer case can either have positive air pressure where the case funds push more
air into the case than pull out.
So there is more air pressure inside of the case, neutral pressure where air pressure in the case is
equal to air pressure outside of the case.
This is difficult to attain unless you leave the case open and in negative pressure where more air is
being pulled out of the keys than pushed in, creating a vacuum to determine pressure total the CFM
of all the intake fans and the CFM of all the exhaust fans.
If the intake cfm is greater, then you have positive pressure.
If the exhaust CFM is greater, then you have negative pressure.
Neutral pressure would be when the intake and exhaust cfm are equal.
In a perfect scenario, you would have neutral pressure with an enclosed case because no dust will be
sucked in.
Negative pressure would mean that air is being sucked into your case from all the tiny gaps you can't
control and don't have filters on, which means less efficient cooling over time.
Aim for slightly positive pressure with slightly higher CFM intake than exhaust cfm.
This way the air enters your case, goes through a filter fills.
