You can see the fan right in the center of that picture. Anyway, the standard running speed for this fan is 9000 rpm, and it lacks any sort of speed control. I recently heard a strange labored noise from inside the case and noticed that the fan speed had dropped from its standard 9000 to a mere 7500. Stopping the fan got rid of the occasional...sound, I don't know how to describe it. Like a labored fan, basically.
Anyway, afer being blown out with compressed air and a cold reboot, it's moving at 5000-6000 rpm. My power rails are all fine, so I don't think it's a PSU problem. The actual northbridge isn't in danger; the fan design is retarded and the northbridge doesn't get terribly warm anyway. But I'm concerned about what's going on and wondering if it doesn't imply more serious problems. In any case, I'd like things to be back to normal...
Oh, and if I end up replacing this stupid fan, I'm looking at the two Zalman passive coolers. What's the difference between the two (the blue and the yellow) ?
[EDIT] The fan speed appears to be rising slowly after the system has been running for a while. Don't know if it will reach nominal speed again. (Later: no, it's not happening. It's not even reaching 8000 rpm. The fan's probably dying, eh?)
