When I rebuilt my desktop computer about a year ago, I bought a new power supply to feed the upgraded central processor. I avoided spending much money on the power supply, though. After about a year, I think the fan bearings aren't quite as smooth as they used to be, or something else there has become less-than-perfect. Increasingly often, I hear a faint sound:
wrrn wrrn wrrn wrrn wrrn
A vibrating sound, about 150 beats per minute, like the fan is just slightly out of balance.
Except for a few days a week, I'm in front of this computer or in the same room for most of the day. Wrrn wrrn wrrn wrrn is starting to drive me nuts.
I'm hoping that soon I'll be using this computer a lot less, partly because I won't be here during the day and partly because I'll be able to use a new notebook computer when I am here. And then eventually I'll replace the case and power supply on this computer.
Until one of those things happens...
wrrn wrrn wrrn wrrn wrrn wrrn wrrn wrrn....
