Where should I put my fans for best airflow?

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.

What is the best case fan configuration?





It’s generally best to place your intake fans at the front and bottom of your case, and the exhaust fans at the rear and top. This is because hot air rises, leaving a more natural airflow. Side-mounted fans aren’t as common, but should be used as an intake if used at all.

What way should a ceiling fan turn in summer?





During summer months, your ceiling fan blades should be set to spin counterclockwise. When your ceiling fan spins quickly in this direction, it pushes air down and creates a cool breeze. This helps keep a room’s temperature consistent throughout the day and reduces the need for an air conditioner to run constantly.

Should I put fans under my GPU?

To prioritize the GPU cooling, you’d place the CPU AIO on top of the case as an exhaust. This will make the CPU slightly warmer, but your GPU will stay cooler. With a traditional tower air cooler, you’d optimally want the fan located on the cooler’s heatsink pushing air towards the rear exhaust of the case.

Are GPU fans intake or exhaust?

GPU fans act as an intake which is pulling air in and blowing out of the rear ventilation holes. If you have fans mounted at bottom or in front then they generally should be acting as intake to bring cool air into the case.

Filtering exhaust fans is kind of like an exercise in futility. The dust has already entered your computer case, and all the exhaust filter does is help KEEP it in the case. The intake fans are the ones that need to be filtered.

Is 2 intake and 1 exhaust enough?



In my opinion, two intakes and one exhaust is the optimum setup if you want to keep a clean case. When all the intake comes from one source and is filtered, your case will stay clean. One exhaust is ok to direct the airflow past the cpu cooler and out the case. Beware of using a second fan; it is counter productive.

When should I use exhaust fan on window?

If the air cools down significantly at night, you can open a window and put the fan in exhaust mode, which siphons hot air out and pulls cool night air in. Our only quibble is that this fan can rattle a bit, so keep this in mind if you’re particularly sensitive to sound.
