As far as the fan speed goes, that's normal and has been that way since Lassie was a pup (so to speak) and cannot be changed, even in MSI Afterburner..Only a fixed, manual fan speed can be assigned with a hotkey to a user profile which you can press to enable at any time..While clock speed/OC settings can be assigned per-profile with a hotkey, a custom fan speed curve is a global setting that applies across all profiles..A per-profile custom fan speed curve may be implemented in the future, but in the meantime, that's just the way it rolls..I'm sure that your request, as many others, is/will be taken into consideration by the EVGA software development team.
 
In addition, sometimes settings have been know to 'carry over' into a Precision update which may be resolved by uninstalling Precision (X/XOC) and then deleting the Profiles folder (which contains the .cfg files) located in the Program Files (x86)\EVGA folder, rebooting, and then reinstalling Precision (X/XOC). 

Hello,
 
I am sorry to hear that. So even when you save a fan curve to a specific profile, if you were to use a separate profile and then go back to the custom fan curve profile your settings are no longer there?

So... is that that? Or are we going to fix it?
