system fan 90B

[Samarrai]

HP Pavilion 15 laptop 15-e010ed
Windows 10 64-bit home.
Intel Core i7-3632QM CPU @2.20GHz
16 GB RAM
1T SSD
I have problem with system fan (90B and getting this error message each time starting my computer) but can't find anyway even when I did the following:
- Reset the computer system to the factory setting (didn't fix the problem).
- Installed brand new original HP CPU fan (didn't fix the problem).
- New thermal / cooling paste applied (didn't fix the problem).
- Cleaned the whole vents and fins (didn't fix the problem).
- Updated and flash the BIOS from HP website (didn't fix the problem).
Edit:
- Power reset (hard restart) didn't fix the problem.
- Removed the CMOS battery (didn't fix the problem).
*The fan always running loud (at high speed) but the air that comes out of the computer is cold.
*HP support: identify your laptop, failed to find my laptop! 

So, can someone help please?

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help,

I understand that your HP Notebook fan is not working correctly and gives error code 90B. If you have already performed the steps from the document HP Notebook PCs - System Fan (90b) error message: https://support.hp.com/in-en/document/c03620929 and the issue persists, it could be a hardware failure. 

Please reach out to HP Support in your region regarding the service options for your computer. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/

Thank you ECHO_LAKE for making time to respond to my thread.
If we assume its hardware issue, can the BIOS still able to control the fan speed even with hardware failure?
Because I was able to slowdown the fan speed from the BIOS settings by disabling Fan Always On so in this case it's more likely software issue, isn't it? 
*Note please I'm not sure whether it's  hardware or software, but just trying to transfer my experience to this topic to find where the problem is..
However, after disabling Fan Always On from the BIOS the 90B error code disappear, but at the same time the fan running always at ideal (quiet at regular speed) but that's not good enough, because when use some programs such as video editing software, running antivirus, watching 4k videos on youtube the CPU temperature rise up and the fan still at the same speed which not enough to cool the CPU.

Off topic;
I do have good skill to work on laptop hardware, so if you think its hardware issue what HP pavilion 15-e010ed motherboard compatible with mine? 
Since it's hard to find the 15-e010ed motherboard anywhere where I live..

Thank you very much for your attention!

Thank you for posting back. 

The error 90b refers to hardware failure code and the system board needs to inspect by a service center. 

As we have limited support boundaries in the support community as of now. I would request you to contact our Support and our Support Engineers should be able to sort this out. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/
