Question about ASUS A8N-E Motherboard
my cpu fan has become noisy intermittently though. asus probe shows temp of cpu normal (42-43 c max). changed bios settings for cpu fan from 1200 rpm to 800 rpm. error messages"cpu fan fail or speed too low" even after that.suddenly new error message "chip fan fail or speed low".after visually checking it i found out that the chip fan spins some times and doesn't other times. the message frequency has increased to almost everytime i boot nowadays. does the problem lie with cpu fan/chip fan /smps. the voltages are in normal range (as shown by the probe). the frequency of cpu fan from 3600-4400 rpm. the chip fan when detected runs at 4500 rpm -5500rpm. the noise of the cpu fan is usually accompanied by drop in chip fan rpm count.the count rises when the sound of the cpu fan dies down.
i have been advised to change the cpu fan. i want to make sure the problem lies with the cpu fan. plz suggest.
I had tons of problems with these Asus chip fans. I asked Asus to deliver 12 replacements (as I had a lot of pcs at that time with the same problem) It worked well, but placing a tiny heatsink well glued to the chip worked well also, as long as one does not want to overclock the thing. It's true that the temp raised a bit, but it remained pretty much in the tolerance area.

Yes. This sounds like a fan issue. The noise often comes from bearings failing within the fan. Also, a failing bearing can make things harder on the motor as it brings the fan up to speed. This is likely the reason that you see increased warnings during the fan speed check while booting because it comes to speed more slowly as bearing wear increases.
I give this a 90% chance that your CPU fan is causing the issue. Since a decent CPU fan will cost you ~$20 online, it's not much out of your pocket if you happen to uncover another culprit.
I'll keep an eye on this post. Let me know how things go.
