Speeding up GPU fans, name?

While overclocking my gigabyte 980 ti xtreme windforce card I was playing around in the BIOS and I increased the max fan speed from 3600 to 4200 in the BIOS. However, the fans don't have enough power for 4200RPM but they are spinning at ~3760RPM instead of the regular 3600RPM. You could argue that I 'overclocked' my fans. However, I know that overclocking is not the correct term as there is no clock involved in this process.

I'm looking for the name of what I did, any ideas?

(no, it's not overvolting because I didn't increase the voltage, I just increased the max PWM signal)

Fan tuning.

Theory is when you know everything but nothing works. Practice is when everything works but you dont know why. In this computer, theory and practice are combined: Nothing works and i dont know why.

 

Atleast i can manage Some things, like my current OC personal best.

If you want to brick your fans, continue doing this.

Pascal Undervolting topic, get more out of your card with less power!

Why high refreshrate monitors look better even without Freesync/G-sync in one image.
Stutters, framedrops, "lag". How to provide detailed information with your "bottleneck" question, as well as a few solutions.

How does one brick his fans by editing GPU bios xD

You are making them run faster than recommended resulting in them wearing out faster due to more power and higher speeds. You will break them very quickly by continuing to do this.

Because the bearings are made for a specific RPM, and are lubricated with this in mind.

Because that motor is made for a specific RPM and fucking with the timing could desync the inertia of the motor with the coils.

Because you don't know where the resonance and anti-resonant points lie. You could very well drive the fan into resonance and even further destroy the bearings.

I know about them wearing out faster and with them (the motors) maybe getting a tad bit hotter than normal but I'm only running them at that speed when I'm actaully benchmarking my PC which isn't thaaaaaat often. Most of the time the fans are off actually. So unless it would reduce the lifetime by 100x it won't be such a big problem.

Also, I'm most likely gonna make the upgrade to pascal when possible anyways so it won't have to last for years anyways.
