Hello All,

Might be a newbie question but I'm still learning the ropes of building, here is the picture of my Cooler Master MasterLiquid ML240L fans, I h ave one facing each directions and can't for the life of me remember which one is facing the correct way, it is on top of my chassis and is meant to be sucking out, the way the picture is taken is facing down so into the machine, my question is which one do I have to swap around for it to extract the hot air from the machine?

Cheers,

If you could unscrew the fan and look around the black plastic shell - there is usually an arrow that points in the direction the air blows.

However if you want it to blow hot air up and out of the case, the coolermaster sticker on the middle should not be visible - so you will need to flip the left fan over.

Excellent, thank you very much for your reply, I will flip that fan around now.
 
Picture is worth 1000 words.
It looks like the one on the right is correct.
Both fans should exhaust to the top in my opinion.
If both suck in cooling air, your cpu will be cooled better, gut your motherboard and graphics card will get the hot air.

You can verify fan direction by dangling a tissue near the fan.
