you really should do some reading on this sought of subject, unless this is meant to be a joke, most people who overclock use a setup similar to this, I my self have 3 fans blowing in and 3 blowing out, even people who don't overclock use a setup similar to that which you stated, I still don't know whether ornot to take this as a joke
the majority of people use d multiple fans-im not even overclocking and i got 4-1-120mm sucking from the cpu with a duct. 2-80mm sucking out of the case and from the PS, and a high cfm 90mm blowing on the video card HS to keep the heat down.
Three fans?? Must be the economy model.
I have 2- 120mmPanaflo 69cfm blowing in (1 in front & 1 on the side towards the CPU and video card)
1- 120mm Panaflo 69cfm on top sucking out
1- Sunon 92mm sucking out below the PSU
2- Sunon 80mm above the PSU sucking out
and the 2 that are in the Enermax 431watt PSU.
