First, take off the side cover of the pc, then turn it on. Now either the fan turns or not.
if it does: Go buy a thermal- leading - pasta (in your next computer shop), then de-electrolyse by hitting something that is grounded with your hands (Like the side plate of the pc laying on the ground), take off the fan as shown in the instructions of your mainboard / cpu and put a whole lot of the pasta on the cpu (DONT TOUCH IT! ONLY WITH A TOOL/PLASTIC!). When it is creamed evenly on the cpu, get the fan back on
If it does not: Turn the pc off, get a vacuum cleaner, then put it on LOWEST ENERGY, hold the fan (or take it off the mainboard completely as shown in instructions) so that it does not move (important! Otherwise it will act as motor and may damage your cpu) and get the dirt and stuff out of the fan.

boot-up fan-errors are caused by a missing-spinning signal...either the fan is not running or something else causes it...it´s not the thermal cpusensor, so i think i can skip the thermal grease part.
to clean the fan is always a good advise, simple solution putting a toothpick in the fan..so you can clean with full power :-)

It´s possible that you have huge amount of dirt in your pc/fan that sometimes prevented to startup the fan

Alright, thank you both! I din't actually notice than you and EddyGaming were two different people due to the similar avatars.
Edit: The fan doesn't look like that even slightly. I did open and clean up my whole computer a few months ago, so there's barely any dust right now. But maybe the dust could be inside the fan somehow?

it´s possible....it´s also possible that bearing of the fan is the problem....lubrication...depends on the type
a problem with the bios, signalgenerator or cable is unlickely, cause you said the error is gone for now
if nothing helps, replace the fan...

When I turned my PC on, it gave me a screen that said "CPU fan error". Should I be worried about this? What should I do?
