I have a five-year-old ASUS motherboard that has been working fine for me for years, until I attempted to power it on yesterday and got a CPU fan speed and chip fan speed warning.

Cracking open the case and powering the computer on, I can see the chip fan working, but it appears to be hitting something as it makes a very loud buzzing noise. The CPU fan, meanwhile, starts up when I power on, but slows down and stops after a few seconds!

How can I address these problems? Is there any way to fix these sort of fan speed issues without just replacing the fan (which in the case of the chip fan, probably means replacing the whole motherboard)?

disparity between `top`'s given CPU % and process CPU usage total

I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop. As an example: I recently ran a git filter-branch --index-filter on a fairly large repo, with the index-filter command… >>> More
