Cooling Fan Is Always On Max High, When The System and Battery Temperatures Are Low

[NotebookUser15]

Hello! I need help:
I had an issue with my fan making a cluttered sound, and I have little experience in working with circuits.
I opened my laptop, did not remove the battery,  unscrewed the fan, unplugged the fan's "circuit" cord, and removed the dust with a swab (I do not have compressed air with me.) 
I mistakenly did not ground myself to ensure that none of the components are affected by static, and am wondering if that is causing my existing issue.

After putting all the components together and turning on the laptop, the fans sounded normal, but gradually grew louder and louder, until it reached a max speed setting.
After turning off and then on my laptop, I received a "System Temperature (90D)" error, with it stating that a "Thermal shutdown has occurred", despite the fact that I turned it off not because it was overheating.

I tried disabling the "Enable Fans" setting on my old BIOS system of F.38. It did not change anything when I restarted my laptop. I changed it back.

I tried looking for HP updates using the "HP Support System" app, but it did not find anything helpful. 
I tried turning on/off my "HP CoolSense" app, but it did not do anything helpful.

After running a complete, long HP System Diagnostics Test, It concluded with all tests passing. The lithium ion battery had a temperature of 39 degrees Celsius, and the hard drive had a temperature of 28 degrees Celsius. Interestingly, the fan information only showed for one fan (there are two), showing that its status is "Not Supported".
I have also downloaded and installed an updated BIOS system of F.53, but after restarting, the cooling fan(s) are still on max high, despite the laptop temperature being low. 

I have run out of ideas on what to do with my fans running on high at all times. 
I do not think it is a temperature sensor issue, but perhaps a hardware issue with the fans.
When I was cleaning out my fans, there was no need to remove the heat sink to get to the cooling fans, thus no need to reapply thermal paste.
My last assumption is that I messed up a component via static energy, that disallows the fans from recognizing the temperature of the PC and/or be able to change speed.

The noise pollution of the fans are very distracting for work and home...

Please help.
