Hello fefe128,
 
Most firmware updates (official) are to fix some minor issues (if any), are you experiencing issues with your video card?

The only update (official) we have is to make DP priority at boot ONLY (no other changes), this wouldn't apply in your case.
 
Have you tried cleaning the card, perhaps replacing the thermal paste on the GPU (this doesn't void the warranty), using precision x oc to increase the fan speed?

Make sure the card isn't running at full clocks at idle. Higher clocks will produce more heat.
 
Here are the top causes of why a GPU would run at full clocks at idle...
 
#1 You're running multiple monitors. Fix: Enable mutil display power saver using nvidia inspector.
#2 Your machine has a virus. Fix: Scan computer using malwarebytes.
#3 One or more programs running in the background are using your GPU. Fix: Perform a clean boot of windows.
#4 Power management mode inside the nvidia control panel is set to prefer maximum performance. Fix: Set power management mode to adaptive then reboot your computer.
#5 Running a resolution of 2560x1440 @ 144Hz. Fix: Change refresh rate to 120Hz.
#6 K-Boost is enabled inside Precision X. Fix: Disable K-Boost.
#7 Shadowplay is enabled inside geforce experience. Fix: Disable shadowplay inside geforce experience OR completely uninstall geforce experience from your machine (highly recommended)
