========================
Detailed description: The fans on my new laptop were stuck at ~5400RPM (Both GPU and CPU, according to armory crate) after it was factory reset by the seller before purchase. It stayed this way the entire way through the setup process and remained after it was complete. I restarted the PC after setup to no avail. I updated everything I could find in MYAsus, Armory Crate and Windows Update. This included a bios update and updates to many drivers. After this it still persisted. I gave up and shut the PC down. After rebooting the PC the fans were operating normally. This was fine until I installed and started a game on the PC, after a while in the game the fans again went back to ~5400RPM and remained for hours after all applications had been closed and temperatures were low again. This same behavior, I have now discovered occurs after restoring from sleep as well. The only way to resolve this behavior is to "Shutdown" the PC and start it again, "Restart" does not help. I have looked in armory crate and MYAsus for settings. MYAsus points me to armory crate. In Armory Crate the profiles work well so long as the fans haven't gone into overdrive and the fans adjust accordingly. Even the max speed setting turbo has only reached 4200RPM fan speed for me so far. Once the fans take off to ~5400RPM the laptop stops responding to any profile changes in Armory crate. I have opened the UEFI to check for settings there but have not found any fan related settings available.
I have noticed online several other Asus laptops have this issue or something like it, even on this forum.

Most fixes suggest 3rd party fan control software to override whatever software is going rogue with the fan speed. Which I can do, but I feel like this should not be necessary just to control fans on a new laptop. Others suggest opening the laptop and reseating cables, which I am comfortable doing but would like to know about any warranty implications before doing so?
I am prepared to take it back to the seller but they have no more boxed new PC's. From what I can tell from reading online this issue seems to be triggered after the first factory reset or after a bios update. So I will either be given a floor model (which will get factory reset) with the same issue. Or they will send it for repair, where all they will likely do is preform a factory reset shut it down and reboot and call the issue fixed only for it to reoccur as soon as I get it back. I have been down this route before and it is long and arduous and I would like to see if there is a possible software fix before I do this?

Hi,
I've run this tool before and I've run it again now, both times it has come back saying "No Problem Found".
When you say it is likely software related, this issue started the very first moment I turned on the PC after a complete factory reset. In which case this is an issue with the preloaded PC software. I have uninstalled a few pieces of what I considered bloatware since then. Much of the remaining software looks far too integrated in the system and I have suspicions that some PC functionality will be crippled if I try to uninstall them. 
I can try removing each piece of preinstalled software to see if the problem disappears? However I have encountered issues in the past when removing vendor Bloatware. On an old Toshiba laptop I was working on, proprietary vendor drivers were uninstalled when certain seemingly unrelated and unnecessary programs were removed. 
My top suspect would be Armory Crate. However I have seen several posts where removing Armory Crate, makes certain features stop working. For example: https://zentalk.asus.com/en/discussion/20220/how-to-fix-this-i-uninstalled-armoury-crate-from-asus-t... and as seen above reinstalling doesn't undo the damage. Additionally it is integrated into the BIOS/UEFI, further deepening my suspicion that this will cause me headaches if I attempt to remove it.
My other suspect would be MyASUS, AFAIK it controls the fans on some other ASUS laptops. However it seems like on my laptop Armory Crate has been given control over the fans instead.
If it could be software related do you have a suggestions on what I can try to remove/reinstall?
As an addendum, I am noticing a pattern. The issue seems to only happen once in a 24H period. First time I boot up the PC every day within the first 2-3 min it will spin up the fans. So then every day I shut it down and turn it back on again. After which the problem does not return till the next day. So there seems to be some schedule that this operates according to.
