Hello.
I just went through this whole riggamorale with my Titan X (not water cooled though).
I did all of the stuff, + re-applied thermal paste (arctic silver 5). Well, gaming temps went up by 2-5c. Yes, up, except idle temps went down 2c (although AS5 paste is known to have a break-in period of a month).
My games still were all wonky, and desktop slow as slow can be.
I was fortunate enough to have another card to throw in to test (I didnt even uninstall the drivers, left them on).
Well, with the old card, everything was great again, desktop, games, etc, worked great again.
I rma'ed after that, and evga said no problem.
I think my issue was with the memory or something though, as the temps did get a bit higher than usual (but only a few c higher than normal).
So, if you have tried everything here, or dont want to waste 2 months (like I did) fiddling with it to see if it gets better with newer drivers, or using a oc tool to watch temps and fps in games and note them all down, then retry with different drivers etc, and up the fan speed via tools (which I eventually had to do to make the card even remotely playable), then just do the rma.
Seems the 900 series cards qa (or the boards themselves) are just hit and miss (I have been with nvidia since the 90's, and never heard so many problems as these have had, besides the 440o series fans being louder than vaccum cleaners, lol).
