Which way is airflow CPU fan?

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.

Is CPU fan intake or exhaust?

CPU fans are designed for exhaust, as they blow the hot air away from the CPU, but some dual fan CPUs have two fans, one as intake and one as exhaust. Cheers mate, hope this helps.

How can you tell which way the wind is in a fan?

The blades should be rotating from left to right (clockwise). You can also stand directly under the fan while it’s on high speed; whichever way you feel the least amount of cool air is the correct direction.

Does it matter which way your 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).

Is one exhaust fan enough?

Having at least one intake and one exhaust fan should provide a substantial temperature decrease versus having no fans at all. Play around with the positioning of the fans, you might find that one fan up top and one in the rear consistently provides a few degrees lower temps than both of them in the rear.

Should the CPU cooler fan direction?

By changing the direction a fan is mounted, it can act as either an intake or exhaust. 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.

Should CPU fan point up or down?

It’s best generally to have the fan push air out of the back of the case and not the top, hot air rises and your video card would be directly below so it’ll be sucking in heat through the fins.

How can you tell the difference between an intake fan and an exhaust fan?

There should be arrows embossed in the fan’s frame or printed on a sticker that indicates the direction of air flow and the direction that the fan blades spin. It is you who decides whether or not the fan is used as an intake fan or an exhaust fan based on which way you mount the fan onto the computer case.
