Anyone seen a good whitepaper on fans? Should they both point OUT or one IN and the other OUT? What is "processor Zone 2" in an Intel motherboard?

I figure you will get lots of opinions on this subject. I myself run 2 80mm
fans pulling air in with a Exhaust Slot Fan mounted in the bottom. I say
that you need some kind of exhaust so point 1 in and 1 out.

<What is "processor Zone 2" in an Intel motherboard?>

I don't know if this is what you are looking for.

shouldn't this be at the top since heat rises?? I have an intake located at
the near the front bottom and a exhaust located in the rear top and also a
side exhaust fan.

My system temp is always around 28 degrees Celsius. Also have a 120mm PSU
fan.
 
<shouldn't this be at the top since heat rises>

With the Power Supply fan blowing in at the top 1 80mm fan blowing in at the
top 1 80mm fan blowing in on the side there isn't going to be chance for the
law of physics to come into play.

It's a Vantec 520W.

Most power supplies blow the heat out the back. What make is your power
supply ?

Gee, if the laws of physics don't come into play, how does your case get
cooled?
 
Looking at the Vantec website .....all 3 fans blow hot air out of the case none
of the fans on the PSU blow in.

Yes, I wandered around the Intel site until I got thoroughly confused with
data. It starts with "processor zone 2 is board dependant" and then points
of to the beginning again. I sent them some email with only computer
responses. I guess they don't care about my business that much.

I have the Intel Acvtive Monitor on my computer (D845GBVL)
and it reports Processor Zone and System Zone
Temperature Sensor Variations


Processor
The processor zone temperature sensor gauge is designed to
provide you with an approximate temperature range for your
processor, so that unusually high temperatures can be
quickly and easily detected. In the event of a processor
zone temperature alert, refer to Alert Response. It will
provide recommendations for resolving the alert, such as,
making sure your fans are working properly, etc.
The processor zone temperature measurement is approximate
and should not be used to validate thermal solutions. The
processor temperature that Intel(R) Active Monitor displays
is read from a hardware monitor ASIC on your motherboard,
which is designed to indicate temperature trends only. If
you are a system manufacturer or a system designer and you
require a more accurate temperature measurement, you will
need to use a more sophisticated measurement device. For
more information on hardware monitoring for Intel(R) Desktop
Boards or the Wired for Management initiative, visit our
developer Web site.


System
The system zone sensor gauge is designed to provide you with
an approximate temperature range for your system, so that
unusually high temperatures can be quickly and easily
detected. In the event of a system zone temperature alert,
refer to Alert Response. It will provide recommendations
for resolving the alert, such as, making sure your fans are

Depends on where the fans are located, AND how many holes in the case.
Cold in at the bottom, Hot out at the top. Take it from there based on
your configuration.
 
Front / bottom fans -- blow cool air in
Back / top fans -- blow hot (warm) air out


Since hot air rises, the fans blowing out should always be higher up in your case.

Thanks all. I found the problem. The "fancy" CPU heat sync (ATT HPS-P4) sold me by Fry's was not up to the heat load generated by the P4 3.2. Once I installed the Zalman CNPS7000B-Cu the whole system cooled down dramatically and stabilized to a reasonable temperature--even at full load. The system now keeps my feet nice and toasty on a cold winter day. The fans also slowed down so none of them are running full tilt (which makes the system quieter). I also found an Intel site that showed where the "zones" were located.
