Hardware madness when switching off BlueTooth? Ghost CPU usage, unwanted FSB switching, noise

Okay, I've been observing weird behavior of the R1e when switching off BlueTooth. Look at this:

Monitor Madness



I turned OFF BlueTooth halfway through. History Graphs of both CPUs look similar.

The image was taken from the current RM Clock beta CPU management utility, which should be capable of handling and monitoring the FSB switching of the Santa Rosa platform. I had set it to high performance, which was FID 11 without SuperFLM (so it should stay at 2.2 GHz clock, which is full CPU speed and full FSB, but no IDA mode).

Now there are two things happening in these graphs:

The obvious is the load on the CPUs, but not on the OS. So the task manager, Process Explorer and most other tools will NOT see that load, not even as Interrupt or anything. I can't confirm the CPU getting hot or drawing more power because of this. In fact, one test seemed to show a very slight cooldown with bluetooth off. However, since the whole device is disables by ATK, the cooldown could be caused by something else, like the coolers inside being connected. Or it was just a misreading on my side.

Then, there is the CPU cooldown, jumping FID and clock rate. (The latter is for some reason not visible in the graph - I believe the RM Clock beta doesn't take FSB switching into account for painting the upper graph yet. The numbers did show it though - see it showing a core clock of 1200!)

What exactly happens there? So the voltage remains constant and the multiplier falls to 6? But then, why would RM Clocks ancient CPU clock graph show wrong readings?! I find it likely that something is heavily misreading or mismanaging here, as all of this makes little sense.

Noise

A high noise in intervals is audible when this happens. It originates from somewhere around the left speaker, power switch, escape key. It seems to be louder when I'm using high performance setting - I haven't found out yet which part of these settings causes that.

Cause?

These things appear when the ATK driver shuts down BlueTooth. I can use the Wireless utility, hardware switch or Fn+F2 combination to trigger it.

What exactly happens there... I don't know. Ideas and comments very appreciated! If you have even the slightest guess of what this couls be, or just want me to test/answer something, post please.

Also, could someone with an R1E please check whether these symptoms apply to his R1E aswell?
