[ale] Kernel and hardware woes

[Dow Hurst]

Because there is such a variance in temperature between people's boxes I 
think a short presentation on proper airflow in a box is in order.  I'll 
do some research between now and the ALE-NW meeting and add what I find 
to my presentation on CUPS.  I think my presentation on CUPs might end 
up being short enough to allow for this.  I have three fans in my box:

It is too loud.
Doesn't cool the CPU like it should.
Blows air all which a ways inside the case.

I think I could show what should be done inside my box as an example. :-)  
Some experimentation on fan placement, vent holes, and proper airflow 
would probably help my poor hot box out.  I've appreciated the CPU temps 
and internal temps that people have posted.  It is telling me that my 
airflow is probably what is screwed up.
