I have a 92mm fan (silenx) on sidepanel, 120mm rear fan and 120mm front fan. The cpu cooler is the stock one.
I'd definitely stick a 40mm fan on top of the heatsink- it fits perfectly as the corner screws fit in between the heatsink fins holding it on good and tight.

What are your idle\load temps with the stock cooler at 328 x 9 ? (I'm only guessing but if your in the 60 - 70c at full load that could be your problem right there) don't know if the stock intel cooler can handle 3.0Ghz as I've never used the stock intel cooler on this mobo.

One more thing.. Have you got a B3 stepping Q6600 or a G0? Some people with the B3 had problems reaching 3Ghz others could reach 3.2 with good cooling. I'm running the G0.
