Should one seal holes in case to create a vacuum?

[Fuddam]

Heard on OCAddiction (if I remember correctly) about sealing all holes (other than those for the fans ) to prevent air leaking into / out of the case, thus creating more of a vacuum effect, thus more efficient air flow.

What do you think?

Someone told me it would place unnecessary strain on the fans, plus it assumes the air intake equals that expelled - if there is a difference, it wouldn't work properly. I know some people run their machines without the case cover on at all, but.....?

any help appreciated.

unless the cfm of your intake fans is equal to the cfm rating of your exhaust fans, I wouldn't do it. You want air to leak in or oput of the case in acordance to the pressure difference.

I agree

Going through the trouble of making a "good seal" would not be worth the small, if any , airflow benefit you got out of it

If the inside of your case is a vacuum, all your heatsinks will be rendered useless.

sealing up the holes would ensure that you dont get air being sucked in from the little cracks in your case, thus preventing dust from creeping in those hard to clean areas. I prefer to just have positive airflow. Whatever floats your boat. I dont think any harm will come from sealing your case airtight, as long as you have a good amount of air being sucked in and exhausted.

Also by purposely creating a vacuum you would ensure pulling air/dust through everything like your CDRW/DVD/CD-Rom/Floppy etc.

I intentinally have one of my drive bay left open so my HDD gets cooled better and to prevent air flowing inside CD drives, because it collects dirt at the bezel.
