Can't Tell Which Way Air Flowing In Fans

I recently purchased six Cougar 12CM CFD Red LED Hydraulic (Liquid) Bearing Ultra Silent Fans from Newegg (http://www.newegg.com/Product/Product.aspx?Item=N82E16835553010). The fans do not have any arrows showing rotation/air flow on them. When I turned one on before installing them it appeared that the side with the brackets/sticker was the exhaust, and the open side was the intake, although I could feel air blowing from both sides (the side with the bracket and sticker seemed stronger).
I have installed all 6 in my case and now it almost feels like my rear exhaust fan is blowing more in than out! Has anyone ever used these fans, and can you tell me what side is the exhaust side? Thank you very much!

If you read the post above you'll see there are no arrows indicating the airflow, hence why the post was created. I checked every inch of them, outside and on the inside of the frame. This does not help.

These are Cougar not Corsair so sadly the link didn't help, I appreciate the try though. These fans do not have any arrows, anywhere on the fan. However you are saying that most fans the side with the bracket (which the fan is mounted to) is the intake? I have read multiple posts on here that it is the other way around. I would like to hear from someone who actually owns these specific fans if possible?

Manufacturer of the fan does impact helpfulness, man you need to get a thicker skin and read more before answering questions on here. Also the Corsair information merely showed it had arrows stamped showing the air flow direction - something I already said my fans did NOT have.
That being said, the second video from Cougar you linked (I couldn't get their page to load for some reason) does help a lot, thank you - am I correct in seeing that the exhaust is pushed out the bracket/sticker side of the fan? If so I have then installed correctly, but I wonder why there is air blowing back IN. Could it be because the fan is up against a metal grate, and that is causing blow-back?

It didn't help so I downvoted it - that's the process, no need to get uptight about it. Furthermore you downvoted me above for simply saying that your first post wasn't helpful? Are you twelve years old?

Cougar vid helped a lot, thank you. Video appears to show that the bracket/sticker side is the exhaust, and the open side is the intake, would you agree?

Side with info sticker is almost always the exhaust on all major brand fans I know. I believe it may be required to put it on the motor, which is usually mounted in the back while the blades are placed on the intake for aerodynamic efficiency. So yes, you are probably right. Wish it were in some way shape or form reversible though, it makes intake case fans look stupid 🙁

Thanks, appreciate the confirmation. I guess you could always place a matching color of round sticker over the manufacturer one lol?

The concave side of the fan blades is probably the exhaust side (since that would be more effective). However, here's a simple trick you can use to check: dangle a piece of facial tissue (or something similar) near one side the fan while it's running, and see if it gets pulled toward the fan or pushed away. That should work for just about any fan, regardless of size or brand.

I updated my post to include logic for why.
Yeah, I suppose you could, but then you'd have to go to an arts and crafts store and need to deal with all the plebs while looking for your serious PC case fan business lol

re try the cougar vid llink I had to refresh twice to get the page no matter what fan or brand unless its some cheap off brand crazy crap its all ways the same as from shown in the first link on the corsair fans as said that was a example to show you I did read but I guess I got internet issues or a site issue and could not post properly all at once had to reenter 1/2 way through my answers ???

''Could it be because the fan is up against a metal grate, and that is causing blow-back? ''

maybe ?? just unmount the fans and see set it of to the side on the table hooked up and running to find out use smoke to follow the direction

I don't know about the quality of cougar fans I do have a old psu from them still works well like 10 years old ??


I guess cugars site is funky I have to try 2 times to bring there pages up even if I'm all ready there

Arts and crafts store? I wasn't talking about decorative tissue paper (though I suppose that would work too). I was talking about facial tissue, sometimes called Kleenex (though that's a specific brand name of it), which can be bought at a grocery store.

Oh no I was talking about putting colored stickers on the fan's exhaust side, the time it took me to write my response allowed you to post. Sorry... ha
