dumb question but how do i know if my fans are spinning the right way

[goblue420]

i mean the rear fans i have a big antec 1080 case, so the two fans rear fans, how do i know if they are spinning in the correct direction?

When more air is blown out from the exterior side of your case in contrast to the interior side.

Look on one of the sides of the fan, there should be 2 little markings looking like this "V->" which shows the direction of air flow and direction the blades are spinning.

Dumb answer by looking at the blades! But seriously, what you should have asked is whether they are blowing in the right direction. If they are exhaust fans, most people want them blowing out of the case. You don't have to look at the direction arrow to find this out just put you hand in front of the fans on the outside of the case and if you feel air blowing on your hand, then they are blowing out. If you feel no air blowing (and the fan is spinning) then they are sucking air into your case.

Not entirley true I accidently had one of my rear case fans facing inword in my case because I could feel some air being blow out the back. Kinda weird but true. I noticed it when I saw the blades were goign in the opposite direction of another fan directly above it. I felt pretty dumb I checked numerous times just to be sure and found it months after I had the case.

Put a small piece of paper over the fan. If the exhaust fan is blowing the wrong way, the paper will be sucked up against the fan. If it's blowing the right way, it will be pushed away. (It's easy to confuse the feeling of air being pulled past your hand with the feeling of air blown past your hand.)

Make sure the paper is slighty bigger than the fan
