Do you need a top exhaust fan PC?

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.

Do you need a rear exhaust fan PC?

Rear exhaust fans are important. They help remove hot air from inside the case and send it out the back of your PC. They are very important in providing airflow through your system. In general, front, side, and bottom fans pull cool air into your case/chassis.

How can I cool all in one PC?

One of the most effective ways to cool your PC is to clean the internal fans. There’s a fan on top the CPU, one inside the power supply, and usually one or more on the front and/or back of the case. Just shut your computer off, open up the case, and use canned air to remove the dirt from each fan.

Is no exhaust fan bad?

It is worth checking if your BIOS has options to shut down the PC based on the temperature of the CPU. This means if you do decide to run without the exhaust fan then your PC would shut itself down if things were getting too hot preventing damage to the components.

Why is the top of my PC so hot?

This is normal: it is simply part of the way that the computer cools itself. If you have a desktop computer which feels hot to the touch, it may have insufficient cooling. If this concerns you, you can buy extra cooling fans or check that the cooling fans and vents are free from dust and other blockages.

Which way should my computer case fan be blowing?

Computer cases that have only one fan in the back should always be blowing the hot air out. A typical configuration is a back fan blowing air out, with a fan in the front sucking in cool air.

Do I need a fan in the back of my computer?

Having all fans blowing in with cool air would give the hot air no way to escape. Tip: It may not be necessary to have a case fan in the back of the computer if the computer has a power supply with an intake fan that blows hot air out the back.

Should the fan be in the front or back of case?

Case fans. Computer cases that have only one fan in the back should always be blowing the hot air out. Another common configuration is to have the fan in the back with a fan in the front portion of the case sucking in air. As can be seen in the picture, the computer case brings in cold air from the front of the case.

Where do I put the intake fan on my PC?

When implementing intake fans (or purchasing a case with them pre-installed), they go on the front of the PC where there’s less outside obstruction. This means we put the exhaust fans on the back or top of the PC, so the airflow travels through the PC, picks up heat, and carries it out of the system.
