Ok, so I have 4 case fans. 2 equiped on the case itself blowing out the top and out the side. I then put 2 80 mm case fanse blowing out the back. My Cpu and mobo temps are higher now. Is this because i have no intake to create airflow? should I have 1 of the 80 mm on the back blowing in instead?

i have allways found 3 blowning in and 1 out is much better.
as with aircraft cooling , a positive pressure works , negitive pressure does not work.
at least 1 more fan blowining in than out , try it!

please let us know what YOU find with this setup.

Alllrighty I have 3 blowing in and 1 out now. Temps on my processer and mobo both dropped roughly 10 degrees. Thanks pap

Steve , Ace and Bull have all gone to a very inexpensive water setup.
ask them what it costs , well worth it.
I use a koolance water cooled case.
