CPU Fan Failure

[WhollyHeretic]

I've got a strange problem here. I have a computer I built myself with an asus motherboard and a socket 754 AMD Sempron, the CPU fan started making noises and then I got a CPU fan failure message when booting. The fan doesn't seem to be getting up to speed and the noise seems to stem from that. I changed the fan and the same problem occurred, I then put in an extra power supply I had to see if that was causing it but the same problem occurred. I also reset the default settings to my CMOS and changed which power connector the fan was plugged into but those didn't help either.

I'm stumped here, any suggestions would be welcome.

1. Nevermind.

It turns out the noise and warning this time were the freakin' northbridge fan. Pretty strange they would die within a day of each other but I found out this mobo has had a lot of problems with the northbridge fan failing. I've rigged up an extra case fan I had until I can get new chipset one.

2. I had a problem with my Asus northbridge fan as well

I don't think Asus uses very good northbridge fans. Mine failed as well (on the Asus A8N-SLI deluxe mb), and I was able to find tons of people having the same problem. I replaced mine with a fanless heatsink made by Zalman. Everything seems to be working just fine, and that's one less moving part to worry about :)
