Fan not operating correctly system fan 90b error

880-112na
Microsoft Windows 10 (64-bit)

so every time I try to boot, it will come up with an error at the start says "a fan is not operating correctly" system fan (90B). the omen still able to boot into windows perfectly fine, and i don't experience any performance decreases or fan issue as all the fan operates perfectly as normal as they have been before the error pop up. the temp of both gpu and gpu are reasonable. i just want to know first why does this come up, and how to get rid of it as it is annoying to have that message for every time i boot up.
