Fan2 running at low speed

[rehanshaikh7]

Hi, I just noticed that one of my laptop fans is running at lower speed compared to the other like if fan1 is running at 2.2k rpm then fan2 runs at 200 rpm. I get a fan error (90B) on boot. Even my laptop goes off after like using for 1 hour or more, when battery reaches around 40%. I tried all the system updates and bios update, nothing worked. Need a solution ASAP
