This should be a easy one to figure out.I put a case fan in front of the case.Should I be feeling more air inside the case than outside?
I guess should there be air sucking in the case?Or should there be air sucking out of the case? Cause when I put my hand over the fan(outside of case) I dont feel any air but when I put my hand over the fan inside the case I feel alot of air.Is this the right configuration?

In my case, there is space that would allow the front intake fan to pull air from inside the case, so I had to install a thick foam strip above the fan, between the plastic cover and the steel chassis, so that it would only pull in outside air.

If a fan is "pulling" outside air into the case, then hot air is also being "pushed" out somewhere else......trust me http://www.PCGuide.com/ubb/biggrin.gif I dont think it matters to much which way you do it as long as you do it.......move air, that is http://www.PCGuide.com/ubb/biggrin.gif

Hey Diurnal,
Yeah, you want that case fan to be blowing towards the inside of your unit.
your power supply fan is already pulling air from the inside or your case and blowing it out the back. Having your extra case fan at the front of your case and blowing it towards the back keeps them working together, rather than working against each other. Not that it's probably that much of a biggy if it was contrary, since most cases have lots of air slots at the bottom (cool air sinks) where it comes into the case and slots at the back at the top (hot air rises) where it exits the system even without a fan just by, what's that called, convection?
FYI I can't hardly feel any air being "sucked" into the front holes on mine either. But I can go to some diagnostics in my bios and see that the new fan has done a siginificant job in reducing internal temperatures.
peace

I've found it's actually better to have a fan at the back of the case, as it helps to draw the cooler air in and over your cpu/peripherals. I've seen as much as a 2* drop in temp on my cpu from having a case fan in the back vs. one in the front-of course you can have both-but only if you want to wear earplugs around your PC constantly. http://www.PCGuide.com/ubb/biggrin.gif
