"CPU Fan Error" message during POST

[Go To Sleep]

As the thread title says, I know yeah why it's saying that because the CPU is watercooled so obviously no CPU fan

I'm just asking how to stop the message from showing during boot up. I'm hoping there's an option in the BIOS somewhere to disable it. Thanks, Jason.

Yep. That's where it will be. But you do have to hunt for it. There is no industry standard for where that setting is, or how it will be labeled, or set by default.

For my Gigabyte board, it is listed as "CPU/System Fan Fail Warning" under "PC Heath Status". And the default is Off on my board. You will just need to scrutinize your manual or the BIOS Setup Menu until you find it.

sometimes if the fan is too slow(i think under 300rpm) during startup it shows this message-had this on a lot of asus mobo´s.
if you dont have that setting that Bill suggested then you would have to set cpu fan reading to ignore

in Dell optiplex, there was an option for disabling it, i just forget the specifics, but the Bios is only So in depth, so it should juts be a matter of time. there was also some key sequences iirc, but its been years.

another easy out, is plugging a fan into the CPU header if one not being there is the cause, as i see you have H2O for cooling.

I would imagine that this would be a good place to start looking...

Fan speed monitor, switch to ignore. I do on mine because the fan's speed isn't reached by the time the board gets to that test in POST. Besides if I have a fan that stops totally I see it through my case window

You have a 7 year old build that you haven't fixed the fan warning on. nor do you know where in the BIOS the option is?

I'd say read the manual lol.

Agreed.

It seems odd to me that a usermade pc ,computer component would have this function built into it, seems more of a prebuilt type function. Generally a fan as well as a sensor that determines temperature. Seems like a s****y built-in function imo.

As I said earlier. Bear in mind its a function to alert those who don't have a window case. But honestly its a little too sensitive for my tastes lol. I think it was more an after thought implementation.

Seconded - I see this often with my setups and simply setting the fan speed reading to "Ignore" will fix the issue.

You can also set voltage readings to "Ignore" if you happen to get a "CPU Overvolt" error or just a general "Overvolt" error. With some boards you have an option to enable "Extreme" voltage/tweaking, this option when enabled should also do away with such errors if you see them.
However not every board has this option so thats normally how you'd solve the problem with it even if for some reason enabling "Extreme Tweaking" doesn't fix it in itself.

If you are looking! It is more likely you would set it via your temperature monitoring program, if using one (I use CoreTemp) or you would notice your CPU throttled back in speed, or your computer suddenly shutdown to protect itself. If a CPU fan suddenly stops, or never spins up, the CPU's temp can go from cold to overheated in just a few clock cycles. And with 3 billion+ cycles in a single second, that would be pretty quick.

thats exactly why i bought a case with a side panel window......So i Could look in and see what the temperature was

j.k. i couldnt resist.

You can see temperature? My thermal imaginary is good, but not that good!

I used to think side panel windows were pointless - just for show like fancy lighting when I prefer to pay attention to what's on my monitors and have my cases sit quietly and discreetly off to the side. But now I buy windowed cases because it is a lot easier to look for spinning fans and dust build up. But I still can not see temperatures.

Considering in 2007 I had a TT big typhoon on an AXP 2500M OCD to 2.2GHz and with fan removed it took 30 minutes to shut down due to heat saturation.

I only use Tools Openhardware monitor or CPUID Hardware Monitor, when I'm trying to find stable clocks, other than that tools are off.

You can't see temperature?

But I digress this is far off topic
