intake fan on case

[chevytrucknut]

Just got my intake fan, but I have a question...In between the case metal chassis and the front bezel of the case, there's the grate where the fan goes. Does this fan go in the HDD area or in between? I also can't figure out which way is the correct way (sucking air), and lastly, should this be plugged into the mobo, or the PSU, because the 3-pin cord they gave is only a couple of inches, but they have an adapter to hook up to the PSU cable.

Thanks for the answers

Normally it goes in between the HD rack and the case itself. If a fan is going into the front of a case, then it should be set to intake (suck) air into the case.

I would just plug it into the PSU. If you want to monitor the rpm of the fan, then you could plug it into the mobo.
