Which way should air flow in a PC?

Which way should air flow in a PC?

Air should travel in clear path through the case. Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. If your case has vents at the top, they should be placed as exhaust fans because hot air will rise.

How do you arrange airflow?

How to arrange airflow in your system.

  1. Intake and exhaust in close proximity on the same side of the chassis.
  2. Airflow blocking surfaces.
  3. Air path size reduction.
  4. Narrow angled air duct.
  5. Having air exhaust to the front panel.
  6. Two fans located perpendicular to each other fighting for air.

Which side of PC fan is intake?

The side with the brand logo on the center of the blades is the intake side. That’s where cool air is taken in and directed to your computer’s internal hardware components. Take a look at the pieces of plastic holding the middle hub or the center of the fan where the motor is mounted.

Is 2 intake and 2 exhaust enough?

Depends on your fans. You can get fans that pull in more than the exhaust and still have positive pressure with 2 and 2. I have 2 intake and three exhaust due to two 280mm radiators and all my stuff stays nice and cool. Dust isn’t that big of an issue if you spray canned air occasionally.

Do GPU fans push or pull air?

They typically pull air into the heat-sink from inside the case. Some coolers can then expel that hot air straight out the back of the video card outside your case. Some cards expel the hot air right back into your case.

Do GPU fans push or pull?

Is positive or negative airflow better?

Positive – there is more fresh air coming into the case than there is hot air exiting the case. Basically, the CFM from intake fans exceeds the CFM from exhaust fans. Negative – there is more air exiting the case via exhaust fans than fresh air entering the case via intake fans and vents.

Is negative pressure bad for PC?

Negative air pressure is where you have more air being pushed out of your case than sucking it in. This causes air to be sucked in through gaps in your computer case, which can pull in dust, dirt, and hair. All of which are bad for your cooling situation.

How much space does a PC need for airflow?

Take a look at where your computer is positioned and remove any obstacles that restrict airflow. For best performance, you’ll want to leave two to three inches of space on all sides of your computer.

How do I know what direction my CPU fan is?

Look for the arrow Some case fans (but not all) have an arrow showing the direction of airflow. Some fans have a small arrow on the casing that indicate the direction of airflow. Whichever way the arrow points, that’s the side that air will blow from.

Does it matter which way CPU fan faces?

The main reason for choosing the orientation of the cooler is the direction of airflow you want. This is as you said pretty much case specific as you said. There aren’t that many cases around with top exhaust fans that are positioned just right (concerning the cpu cooler).
