A cooling fan is not operating correctly

[zSebaah]

hello, a few months ago I removed one fan from my laptop because it was broken and made a lot of noise: I bought other cooling systems, but when I started the computer I was told "The cooling fan system is not operating correctly, Error System Fan 90B ".

While I play PC, there are some annoying framedrops that make me drop fps exponentially.

How can I fix this error?

Hi,

Did you hook up the fans correctly?

On page 52 of the service manual, you can see the steps to install the fans.

Did you buy original or compatible fans, did you replace both fans?

Here you can find original HP parts:
