Cleaning the rollers is not going to help noise inside the cabinet.
Your problem is caused by a power management feature that makes the processor sleep for only a few cycles at a time. As the computer doesn't need to use the full power of the processor to make the mouse move, and as the mouse has to gradually move across the screen (it can't compute it all at once and be done with it), the processor sleeps a lot. The buzzing/scratching you hear is it turning on and off really fast.
I have this problem, too, but it's on OS X. A quick Google search didn't turn up anything about processor power management on Linux, so perhaps someone more knowledgeable on this subject will come along shortly. Or maybe now that you know what it is, you can figure it out.
In any event, the solution is to make the processor run at full-power all the time. You might not want to do this.
