Which way does fan blow air PC? 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.

Which way are PC fans supposed to face? When mounting case fans, air flows across the open side towards the side with the protective grille, like so: So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top.

Should top PC fans be intake or exhaust? 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.

Should CPU cooler intake or exhaust? Intake is better for the thing that is being cooled by the AIO. Not for the system. CPU performance doesn’t degrade if it’s 2-3C higher (intake vs exhaust), as long as it’s below the throttling range.

Which way does fan blow air PC? – Additional Questions

Is 4 fans enough for a gaming PC?

A gaming PC will need at least three case fans to properly regulate heat and keep the components cool. At the minimum, two case fans are needed for optimal cooling, and ideally three.

How much heat can a fan remove?

The amount of heat that fans can remove is significant. For example, a 750 CFM fan operating with a temperature differential of 20 °F removes 1500 watts or 5000 BTU/H of heat. This is as much as an air conditioner.

How do I vent my PC heat?

The easiest and most effective way to dump computer heat outside of a window is to add a window AC unit. You could try ducting exhaust outside the window, but then you’re blowing the climate controlled air out of your home.

Adding an additional pair of intake and exhaust (for a total of four fans) will likely lower your temperatures anywhere from two to five degrees. That can be significant but anything beyond that and you are likely to see a diminished return in the range of one to two degrees, if that much.

How many cooling fans should a PC have?

Ideally, you need one exhaust fan in the back and two intake fans in the front of your case to create the perfect airflow. Install the two intake fans in the top and bottom slots (i.e., leave the middle slot empty) to maximize airflow to your CPU, GPU, and motherboard chipset.
