After looking at the case, I would recommend that you place the highest air
flow fans in the lower front of the case you will have to remove the front
plastic covering. From the pictures it looks as if it has three plastic
hole snaps. If they are snaps, just slightly squeeze and push on the snaps
at the same time. You may have to use a screw driver to pry on it a little.
If it has screws just use a screw driver and remove the three screws from
each side.
Look at the amperage or wattage printed on the circular center of the fan
the highest amperage or wattage fan usually has the highest air flow. If
you look on the side of the fan there are general arrows which show the air
flow direction. If they don't have arrows the fan will move air from the
open side to the cage or fan support side.
Place the two front fans to move air into the case.
Place the side panel fan to move air into the case.
Have the two back fans move air out of the case.
Place the top blow hole fan to move air out of the case.
I believe that the temperature monitor on the front of the case can be set
to read °C by changing the jumpers on the LED from the back side of the
case. Check your case manual to see if this can be done. If not, the
formula to convert to °C is
(°F-32)/1.8 = °C
I live in the south and this time of year with AC on the temperature inside
the house runs about 80°F. I have found that for ever 1°C (2°F) increase in
the room temperature there is generally a 2°C (4°F) increase in the cpu
temperature. Check it out for your self, you can use the ASUS probe
software to monitor the cpu temperature and the built in case thermal senor
and compare the two at different room temperatures. Makes for a interesting
experment.
I believe that this will be the best air flow for your case. A good heat
sink (copper) would help lower the cpu temperature along with some artic 5
paste. Thermalright, Swiftech, and Thermaltake make some excellent cpu heat
sink products. (SLK900, MCX462, Volcano 12) Excellent case and system. Had
a GF3 Ti200 and recently bought a Evga GF 5900 SE made a big difference.
Excellent setup.

vantec volcano fan and reostat (4500rpm)
room temp 24.6°C (77°F)
room temp = 27°C (80°F) 34°C idle / 44°C load
I have two thermaltake smart fans and 2 sunon 0.14 amp fans on the front
intake.
One side case led intake fan 30cfm.
One top blow led exhaust fan 32cfm fan
Two back pctoys led exhaust fans both adjustable at approximately 42cfm.
Use a thermaltake 420w power supply with temperature controled fans.
The thermaltake power supply unit (PSU) fans gererally operate at 1300 -
1500 rpm.
The measured case temperature is generally about 1 - 1.5 °C above room temp.
My case is a modified design from an older power max case.
I used a old power max case because of the slotted vent across the top of
the case (hard to find).
hope this helps.
