Should I disable CPU fan error message and how?

Question

I have just completed my first "build" consisting of:

• ASUS P8Z77-V-Deluxe motherboard,
• Intel i7-3770 processor,
• Coolermaster Hyper 212 EVO CPU cooler.

Each time I boot the computer, the following error message is displayed:

CPU fan error. Press F for settings

The CPU fan speed varies around 500 RPM and the temperature starts at 70°F (20°C) and goes up to 80°F (27°C).

I know how to get into the bios. When I press DEL I get the CPU fan error message. Then I press F1 and I get into the BIOS where I set the boot priority. Then I press EXIT, SAVE CHANGES ans RESET. But it does not boot. I keep getting back to "PRESS DEL..., etc. What modification(s) should I make to disable or bypass this alert and is it safe to do so?

Solution

I was getting same error message on my Maximus V Gene with Cooler Master 212 Plus CPU Cooler.

This error message is diplayed when CPU fan RPM is below specified limit. For my motherboard, specified low limit was 600 RMP and CM 212 Plus Cooler fan was running at 500-550RPM.

If CPU temperature is ok, then you need not to worry. If you want to turn of this error message, then goto:

BIOS -> Monitor -> Fan Speed Monitor

Here, you can see all fans connected to your system are being monitored. You now need to select CPU fan. Two options will popup - Monitor and Ignore. Select Ignore.

Error message will not be shown thereafter.

Electrical tape works for the "check engine" light on my car.

Having a CPU fan spinning slowly (question indicated 500 RPM) and ready to immediately step up if the temperature increases is far far better than running the system with the cable disconnected. Passive cooling is possible, but you want a heatsink designed for that, and especially do not want unpowered fan blades sitting in the way of airflow.

@IARI Can you specify the motherboard name and model that you are using?

Maximus VIII Ranger - are there multiple models of that?
