PC fans winding up when shuting down is this normal?

[Liamp36]

Hi so i have been using my pc alot more recently and i know its normal for a pc to take a while to shut down but when mine is in this process it often spins the fans up alot before turning off or the fans wind up and down randomly 

 

is this normal?

 

any help is greatly appreciated thank you

Depending on your settings some pcs do this as an anti dust thing. Basically forcing more air through it to try and get rid of dust that has entered and settled. 

 

Only one idea but issues can cause it as well.

chances are your fans are controlled by some sort of software and when shutting down it doesn't tell the fans how fast to run anymore, they get confused and ramp up just for safety reasons because they think they clever. wouldn't worry too much.

Have this issue as well. When you shutdown your computer, all the software is closed and the fans have just pure voltage going through them, no controlled voltage or RPM. It is normal and you should not worry about it.

What motherboard is it?

 

As @8uhbbhu8 said, there is a de-dusting thing. I have a Z97 that has the same feature and the fan installed in the ASST fan header will spin for another 30 sec before shut down. I did set it up to run at normal speed and not ramped up.

There's nothing to worry about. Might be annoying but it's fine.

Speccy and several hardware monitors will do if you don't want to open case.

Model name is usually under first PCIe slot. Or if you saved motherboards box and/or manual, those have it with big letters right in front.

It would help me more if I'd see whole board. But at this point its easier if you just install Speccy, HWiNFO64 or HWMonitor and use that. From those pics all I can see is that mobo is ATX, has brown PCB and two bottom slots are legacy PCI.
