Should I be worried about installing this?  

Uninstall this garbage tuner, its riddled with bugs and Evga made you the guinea pigs....
Download legacy 4.2.1 and Rivatuner 6.2 by Unwinder and you will have 64bit OSD with 0 bugs.....let Evga sort through the mess they created...

The Ui is ugly, impossible to read anything!!nothing works as intended.....except for the fan curve.....gj Evga

No download button, no download link working, please help...

OK I spotted it, still I'd advise you guys please put a download link URL type under the image, thank you. 

I keep trying to set a fan curve but everytime I do, it turns the fan speed to 29% and keeps it there, OR I can keep it on Auto and it has to throttle at my set temperature, OR I have to adjust the fan speed and it stays at that fan speed no matter what temp... I have made a fan curve and applied it but it isn't taking effect. I have the GTX 970 SC Reference GPU... Help?

Edit: I remembered! Double-Left click on the Fan Curve window to switch to a stepped curve.
 
I'll leave the rest here for posterity:
 
I can't figure out how to change to a stepped fan curve.
 
I swear you used to be able to just right click on the fan curve editor (in the previous version).
 
I really need this functionality because my overclock settings were based around it, and now my custom fan curve is gone.
 
I use the hysteresis variable and it's designed for use with a stepped curve.
 
Please, if anyone knows how to enable this, let me know.

I installed evga precision 5.2.3
I have 3x GTX 780 3-Way SLI.
Setting the overvoltage lives its own life and work as he wants.
Without overvoltage I 1012mv 980MHz (default), as I turn the voltage overvoltage jumps on 1156mv! From this value until I can raise them. But how do I set 1025mv if value begins with 1156mv??

The second issue.
When switching profiles between 2D and 3D return to the set voltage jump higher! Sometimes about 18mV! Surely this could damage the card!
Why such a half-baked program available over EVGA?!
As soon as you amend your voltage regulation but the 780 series cards.

Damn, what a (Word deleted for foul language) mess. Uninstalled. Back to MSI.
 
No more EVGA cards for me. Company is rotting from the inside.
