It's not that i can't boot up or cpu becomes too hot. ... it's fan speed. I have Zalman CNPS9700nt, and using Q-fan of the mb. As soon as i overclock my cpu over 2.8, the fan starts to run at 100%. Now, in BIOS, it says that BIOS will ignore Q-fan if cpu runs at very high frequency ... So, i think that is causing the fan to run at 100%. It ignores Q-fan and just set the cpu fan speed to 100% (even though temp is just fine) I tried to disable Q-fan, and the cpu fan started run at 100% even at stock speed.

Is there any way to fix this? The cpu fan is way too loud at 100%.

look in your manual on page 4-36 where it says "CPU Q-Fan Mode [PWM]" There are two setting one for a 4 pin fan [PWM] and one for a 3 pin fan [DC]. try DC and see if that works. it also says some 4 pin fans to not meet intels PWM fans spec and Q fan will not reduce fan speed. So i bet it is on PWM and since it isnt a 4 pin and PWM it is defaulting to 100%.

Hope this helps

here is the manual link http://dlcdnet.asus.com/pub/ASUS/mb/socket775/P5W DH Deluxe/e2557_p5w_dh_dlx.pdf

I can't overclock my q6600 on the Asus p5wdh Deluxe board beyond 2.79ghz. Just locks up at post. ANyone have a step by step guide to setting these two for a solid overclock? I ma using a Freezer 7 Pro cooler and I asm looking to hit 3.0ghz.
