Confirming good air flow. Help anyone?

[Circa2000]

I am trying to make sure I have a good flow of air through my computer, I tried the smoke trick, with a match, but once the smoke went in i could see nothing.. any tips on what to use or any other ways of testing?

feel how much air the fans are moving, using your hand, then check out your full range of temps.... post your specs and idle/load temps and we should be able to tell you where you stand.
