CPU Fan Error

This it too technical, not suitable for me. I only need to know how to install and use it.

OK, sorry.

@comcom,

You should always use PWM Fans and, Asus is doing a great job by default at keeping thing cool without excessive ventilation.

Having the fans a full speed certainly keeps everything cool, but on the other hand makes them become dirty a lot faster.

If you have a second emplacement on your case you can also populate it with a second fan. Your MB has 2 (ChFn) Connector.

Having a good balance between temps and speed help having a cool and silent system.

Another factor to consider is CPU temp Swing, you are better having a CPU running at 60° non load up to 90° on load than a CPU running 20° non load swinging to 90° on load (the smaller the is temp range the better the CPU feels)

When I don't use my system all the chassis fans goes to a complete stop and CPU drops to 300rpm. It's perfectly silent and doesn't accumulate dirt for "nothing" while not in use.

Hi, I cleaned the fans in my PC and then I switch on the PC I see this [CPU Fan Error! Press F1 to Resume] (this screenshot is similar to what I see https://i.imgur.com/uiKD57s.png ) I pressed F1 and I can continue to load into Windows 10

During cleaning I accidentally slightly wriggled the coolermaster metal fins (beside the black fan) on the CPU.

Fan noise now is nosier than before cleaning.

Q1. What shall I do now? Are my fans still operating correctly? If I switch off my PC now will I be able to switch on my PC next time?

Q2. Is the black fan beside the metal fins operating correctly?

Q3. The back fan (white fan) seems rotating slow or is that normal? If I remember correctly the white fan used to spin faster and produce bigger wind.

Q4. I have accidentally slightly wriggled the coolermaster metal fins during cleaning of the fan, would the CPU thermal paste still be in good condition? I am afraid the thermal paste is detached when I wriggle and cause CPU temperature to rise.

Thanks

That's a known issue with Asus socket 775 motherboards. The AMI BIOS randomly on reboot, bleeps multiple times and says "CPU Fan Error!" and makes me hit F1 or the like. It may happen with post-775 generations. This random error occurs, even with the CPU fan in the correct RPM range!
