What are the mounting points for the case fans?
This will help with giving more information/options for using these. Thanks, -------------------- Techextreme

Ideally you want to match the intake and exhaust airflow (CFM) as close as possible, or have the exhaust slightly higher than the intake
Your cable routing has a lot to do with improved air flow also Different cases have different numbers of cut-outs where a fan can be mounted There can be 2 small or one large exhaust openings in the back, one or two intakes in the front, and possibly one on top and/or the side -------------------- Mark

If you have a front bottom intake opening...and a rear middle-upper exhaust opening...the front one should be mounted so that it brings air in, while the back expels air.

When I ran closed cases, I was a fan of "overpressuring" the case. I ran more intake CFM than exhaust CFM. I ran good filters on my intakes and found that if you overpressure, with intake filtration, you get a lot less dust in there. When you have a lot of exhaust CFM it pulls in dust through every case seam, back panel crack and optical drive.

Hamluis is spot on,
though you can have a variety of different air flows, the best option that works most efficient is low front intakes, high rear outtakes. Due to the fact that hot air rises you will expel more hot air with higher outtakes which in turn draws the cooler air up. I also agree woth dpunishers overcompensating with the cooler air input, dust gets in everywhere so when you expel the hot air it will draw air quickly from the nearest availble hole or crevice. Doing so sucks all that nasty crap into your case which is a nightmare. Filtered inputs that exceed the cfm of the output is definatley a good option, maybe 2 to 1 ratio would be ideal. High500 |
