Issue (In addition to the problem description please let us know if the problems started recently and if you remember changing anything around the same time, etc.)

Three issues:

1. Bios shows FX505 when the laptop is a FX705DU
2. Fans pegged at max even in bios.
3. CPU temp will go from 82c to 42c then back up. This is in the bios under no load and when first turned on.


I have reflashed the bios from the support page for my laptop and even did a fresh install of windows just to be safe. No idea what is going on. Had this issue since December of 2019. Just been busy as this is my gaming laptop and I am home now so I use my desktop instead. The laptop is out of warrant sadly and I can't afford to send it in or buy a new one.

1. Shows the same in windows and on the bottom.
2. Yes I have and no change.

My solution was to do a fresh install and not install any Asus bloatware. Other than drivers there is no Asus software on my machine. Fans ramp up and down like they are supposed to. Only thing is that the proc now runs hotter. But, from what I have been reading, this processor runs hot and the thermal design of the cooler is terrible.

I had no issues using an older version of armory crate but since it auto updates to the latest broken version I decided to forgo it. Not to mention you can't stop the program from updating. I had blocked all asus apps in the firewall yet it still updated. Without any of this bloatware, my laptop runs like it did when I bought it. I just don't have control over the fans but I didn't before!
