Why is my HP laptop showing "System Fan (90B)" error even after cleaning the fan with compressed air?
I am using HP Pavilion DV6-6b51ea laptop. The laptop is 6 years old. For the last 1 month, the fan was running loud (even loud now may be) and since the last 2 weeks, I have been getting System Fan (90B) error sometimes. Some days ago, I bought a can of compressed air and blew air inside the laptop vents (without opening the laptop). Still after this, I am getting the same error sometimes. [p.s:- 5 months ago, a laptop repair guy disassembled my laptop and cleaned the dust in the fan and changed the thermal pastes]
Why am I getting the same error still?

The fan is dying. Replace it yourself or pay someone nerdy to do it for you. I wouldn't recommend running it much, if at all, until this problem is fixed since you could be overheating tiny sensitive laptop components. Here are instructions to DIY, if you are so inclined!
HP kindly provides service manuals which can instruct you on how to replace parts. You can buy replacement parts cheap on ebay with the part numbers in the service guide.
From searching for "DV6-6b51ea service manual" I found the service manual for you here:
