@kelvinnana79347 most common issue with that "Fan thermal Test: Failed" is a bad fan or heatsink (bad thermal paste can cause this) as well. I suggest you check and (clean your fan) heatsink. Replace the thermal paste and if need be, the fan as well.
If you should still have issues with that after then check for a BIOS update (it is possible that there is "miscommunication"). Since iFixit does not yet have any guides for this laptop use the [document|42049] instead.
To replace the thermal paste use something like this generic guide [guide|744]
While you work on your laptop, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
