re: Usual giveaway is either more noise or a LOT LESS noise Saturday, May 14, 2005 at 12:11 pm Posted by Kiwi (2228 messages posted) Also more typically for a majority, you don't even know at first that it is heat, just that the PC shuts down suddenly and you don't know why. When it's a psu fan going bad, it's typically a bad bearing, and those make a great deal of ugly noise when they are dying. Of course, my contribution to the thread presupposes that the user is not hearing- disabled, doesn't it? Occasionally, a bearing just gradually binds the fan shaft more and more tightly, so it won't spin up fast enough to cool the psu, let alone to help to exhaust the PC's heated internal air environment. .

My guess is that it was slowing down to a crawl then eventually failing altogether. And my computer did suddenly go to the BSOD, but not shut down completely. This is the second PS I have replaced in six months, the other being on my older (3 years old) computer. It too smelled of electrical burning and indeed it too was the power supply fan had stopped. I am amazed though at how much the ps fan contributes to the cooling of the case and cpu or should I say to the contributing of HEAT to the system without the exhaust. Either way it is a lesson well learned by all. My video card also started acting erractic, depixilizing, breaking up, etc. So this too would have been something someone would be puzzled by in trying to figure out whether it was the video card or what. The only reason I stumbled upon this is that I downloaded a hardware monitoring program for my son's computer which was shutting down and it showed his temps were okay. (That turned out to be of all things a defective off/on button). I loaded it onto my computer and only then did I know my temps were that high. Lesson learned, monitor your computer. My computer came with a system monitor but I believed I disabled it for some reason, but I remember it always showed an erratic power fan reading, going from zero to 25000 rpm. Maybe that's why I disabled it. (duh) It was trying to tell me something but I had read too many times about unreliable readings and undependable sensors and chaulked it up to that. Another lesson learned I guess. In summation.....erratic video card, overheating cpu, BSOD, shutdown, unusual voltage readings (mine was 13.8), etc. check your power supply.

I added a separate pair of fans to the case, similar to what a newer case these days might have. It has an intake fan in the case side panel, right above the video adapter, and an exhaust fan in the back panel, just below the psu. The same TBird is still in it, but is about to retire now. And it did outlive its first psu by at least a year now. .
