I just managed to get my hand on a refurbished EVGA Titan X SC GAMING card that is behaving a little bit different than from what I expected on paper.
It ramps up to about 4000 rpm under load (quite loud), the GPU clock boosts to above 1300+ (data sheet says 1216 MHz boost clock?), and the GPU temp caps out at about 72-73c (Don't these usually go up to 80-85c?)
 
Is this normal behavior for this graphics card, or am I dealing with a modified BIOS? I've never owned one before and since this is a second-hand card I don't have any reference for how it should behave out of the box.

Thanks! No I generally don't use any kind of overclock programs, as I prefer being hands off on GPU's.
 
I did as suggested and it does indeed seem that the BIOS has been modified. With a fan target of 2400 rpm at 30c and 4800 rpm at 75c, which is vastly higher than than those on file at techpowerup. So I've now registered the card and opened a ticket for the correct original version. :)

Those cards are notorious for the VRM burning up. It might not be a bad idea to keep the fans spinning fast.

Unfortunately I still have to be able to tolerate being in the same room with it!!!
 

Support said they would forward my request to the Tech team, but i got a bit impatient waiting so I found and cross referenced a few BIOS'es from the provided links and chose one that was an identical version match and flashed my card with it, just fine. So now it seems to be back to stock settings. 
 
I also installed Afterburner so i could set a slightly higher fan curve and maintain full boost clocks without throttling. And I have my three 120mm intake fans slaved to the GPU temp by way of corsair iCUE, which should ensure more than enough fresh cool air entering the case. 
 
My main reason for doing it like this is because my system is a Windows XP/10 bual boot system. With XP-era games being infinitely less demanding, stock fan curves are perfectly fine.
