3000 RPM is moderately fast. I'm not sure of the default RPM on Intel fans, but to tell you the truth, it doesn't really matter. If your processor is running in the high 50s on idle, then the fan needs to be cranked up a little bit
.....2800 is low
2800-3800 is medium
3800+ is high
That's an approximation.
My CPU fan on my Barton 2500+ is running at like 3300 RPM. CPU runs at a constant 40 C in idle, 45 C on a load.
