|Cpu Fan Fail Warning|
It beeps when I start my computer sometimes...

Ok, so when I turn on the computer it starts beeping for a second or so and drops this warning "CPU FAN FAIL", then offers to enter bios or press F1 to continue.
When I called the company from which I bought the PC, they said it's normal thing or smth. It's like when the CPU isn't warm enough, it shows this warning. And really, when I tried turning off the pc and on after working for a couple of hours, it doesn't show that warning. My CPU heat at the begginning is about 33 C., normally about 40, when I play games goes up to 50 C.
So I think everything is ok, but that noise is just pisses me off. I heard it's possible to turn off the warning message in bios somehow. I don't want any trouble, so maybe you can clearly tell where to go in bios to turn off that sound?

Have you opened the case and checked the fan rotates at start up? Its possible the motor bearings are 'sticky' causing the fan not to start immediately, or run slow until it warms up.
If you can beg or borrow a replacement fan, try it and see if that has any effect.

That somehow doesn't ring true to me, I've never experienced it, anyone else care to comment?

It's not normal for the protest beeps to happen on startup. But, considering the low temperatures at which it is beeping, it may be a bug. 50 degrees is fine for both AMD and Intel CPUs. Check your fan as suggested and check the cut-off/safety point at which your beep alarm goes off (this is usually in the BIOS); it may be set too low.

Yes, I have. It starts rotating, after a second stops a little and then rotates normally all the time.
Actually they said, it's like the fan is smarter than a motherboard and starts when the processor is warm enough, so MB doesn't recognise the fan at first.

Temperature sensing is done by the mobo. The fan produces a constant pulse stream when its rotating which the mobo monitors to determine fan health. When the fan stops so does the stream, I think this is what causing the warning.
Whether its the start of a major problem, I don't know, but fans are cheaper than processors!

I'll try to get another fan, cause this was pretty cheap. I heard that Zalman is good, what would you recommend?
CPU - AMD Athlon 64 3200 2.0 GHz 939
M - Asus A8N-E 939

I've used the Arctic Cooling Copper Silent 2l which keeps the processor nice and cool and is pretty quiet.
Do you have also have fans in the case?
If not a couple of cheap ones, one blowing air in one side near the bottom, and at the top on the opposite side sucking it out will keep the temperature down.

I have one simple (must be cheap) fan at the bottom back of my PC and that Arctic-Cooling CPU fan.
By the way, I've measured preformance of fans with a soft. that comes with MB driver cd.
My PC fan shows about 8000 RPM all the time. And that CPU fan shows only 280 RPM at the very beginning when I turn on the PC, then goes higher and higher. That soft. wich measures temps and RPM's loads automatically after my pc boots and it "beeps" until my CPU fan reaches 600 RPM. Usually, after 15 min and then all the time CPU fan rotates at 1000 or 1100 RPM.

My PC is very new and I wouldn't want to believe there's a problems with it. That fan is new also but im planning to change it cause that beeping pisses me off. i would disable the warning in bios, but I don't know where. My bios is weird.

8000 RPM? You sure that's not a typo? ;)

Is it blowing air into the case, or extracting it?
It should be blowing cool air into the case, if not turn it round.

Faults are more likely to occur with new equipment. Once its 'run in' faults are unlikely, as it gets older faults become more and more common - its called the bathtub curve.

I've dealt with this warning for years. In my case, it's a glitch. Any indicator shows that nothing is wrong. Try updating your BIOS.

It's blowing air out of my case. I don't know, my old PC I had also blew air out of the case, not into it. I don't want to mess with things I don't know well. I'll just leave it, it's not the problem anyway...
Jo1ene, thanx. I'll try to update my BIOS. But I don't want to mess anything, I've heard that it's not recomended playing around with BIOS. As I undersand it's a soft. right? Is it possible to download it somewhere for free? or it's paid. Now my BIOS shows name PHOENIX. Is it safe to install any other bios? And then how to actually install bios then? Run setup and that's all?...
Sorry, it's out of topic, but I think that whether updating BIOS and trying to turn off warning, or buying new CPU Fan can help me to solve that beeping problem. Installing bios sounds cheaper...

damlag, there is a perception among techie types that any PC problem can be solved simply by yourself. I believe that there's no harm in taking your PC to a competent technician if you aren't confident making changes/troubleshooting.
The BIOS can be updated or flashed [pcnineoneone.com] by going to the motherboard manufacturer's site and downloading the new BIOS and a flashing program. You can sometimes do it in Windows but sometimes have to do it from the DOS prompt. Quite often flashing the BIOS makes changes to settings you already have in your BIOS and could cause all manner of problems. Feel free to flash it if you are capable of hitting delete, going into the BIOS and resetting everything to your specific hardware, OS, software and preferences. From what you say it doesn't look like you are.
You can't install "another" BIOS (technically, you can - but you'll have to pull the BIOS chip off another motherboard of the same make/model). You can only update/flash the existing one and the only place to safely download the latest version is the motherboard manufacturer's site. It is possible for you to screw up the BIOS and if you do you can't get a new one, you throw it out together with the motherboard.
|Installing bios sounds cheaper... |
Cheap sometimes turns out to be very expensive in the long run.
|It's blowing air out of my case. |
Logic states that it should be otherwise (if it's at the bottom) but your PC manufacturer may have had a perfectly valid reason for having it pump air out rather than in.

well heres something you might want to keep in mind...if you get a beep at the beginning its becase the motherboard detects an error somewhere on the board, in your case the fan has had a few difficulties causing it to trigger the sensor on the motherboard, if you have ever noticed that there are three wires to a fan? well thats because one is for power, another for ground, and the last is for the sensor.....so just replace the fan if it shows signs of malfunction, or if you want to leave it alone then go into bios and find the setting where it keeps track of your cpu fan temp and disable it, that will shut down the sensor, or at least tell the motherboard to ignore the warning.....hope that was some good advice for you!

I'll definately try to check BIOS. I tried to turn off warnings in BIOS as suggested in some posts, but didn't find anything.
But if I do that, can I still monitor the CPU FAN speed and CPU temp at AsusProbe Software?

um as far as your software working it might but then again it probably wont work because you disabled it on the mother board and it would make it seem as if it werent there but you give it a try and hope all goes well for you
