whenever i shut down my pc fans go full blast for 2 seconds

whenever i shut down my pc fans go full blast for 2 seconds. is this normal?

I don't see any issues with this. Lots of programs are closing at the same time - extra heat generated - fans run full blast.

or, the software controlling your fan speed (i.e. msi afterburner) gets shut down with all the other running programs and fans revert to full speed just before the power supply stops supplying power

the only thing controlled by my motherboard is the liquid cooler, all other fans are at full speed which is weird since when the full blast thing happens they get way louder which means the RPM goes up? how can the RPM go higher than full speed which it was already on?

Goes up to max RPM; no more.

Not sure what the cause is, but it may be by design.
Regardless, it's kind of a blessing because once you shut a warm system down,
the only cooling it gets is the ambient air. At least for 2 seconds it had a nice
kick of cooling assistance before shutdown !
