An average 92mm 2500rpm uses 0.1-0.2A so 1-2W.
A stock Intel fan is about 92mm and is rated at 0.2A. So around 2.5W.
There should be no difference.

With the stock cooler neither runs cool.
Under Prime95 the Q9300 with a stock cooler hits 70°C just like the Q6600.
The Q9300s 7.5x multiplier limits you to 3.6GHz (7.5x480MHz) if you're very lucky. If you're not it hits the FSB wall before that.
With a good cooler the Q6600 can go just as high.
