on idle my card stays around 36-39 'C but when i play pubg, gpu sits at 81, power at 82 in the precision ocx software. is this normal? case exit fans billowing hot air. quickly drops back down as soon as i exit the game. house is usually at 22-24 'C internally.
 
i set the fan curve to aggressive on precision. no oc beyond whatever the card ships at.
 

I was benching it for a review with an ambient of like 25 to 27,4°C and on 100% fan it had trouble reaching 60°C (117% power limit), and other temperatures were usually some degrees lower on the board.
On half fan speed on all fans with an ambient of like 21°C to 25°C I'd say it sticks around the 60-70 range. (100% power limit)

fans are at 100% from the looks of it.
 
bad card or what? cpu never breaches 40.
 
had a 780 before this and that never reached 70 and that much hot air ddnt exit the case.

Mine is on slave BIOS and does not go over 70C even with a 1080TI sitting in a slot below it Folding 24/7

Thermal performance is a subfactor of the silicon lottery. Depending on how leaky your chip is, it will draw various amounts of power at a given voltage, generating a proportional amount of heat. For example, I have two FTW3s. One slot gets hit by some CPU rad exhaust, and has only one slot of fan clearance for half the length of the GPU due to my sound card. The other slot gets a column of unadulterated intake air and is entirely unobstructed. In one config, the master GPU idled at around 33C, and got to around 66C in GTAV, while the slave idled at 23C, and got to about 51C in the same title for over the same gameplay duration. I physically switched the two GPUs. Now, the master and slave both idle at 26C(sometimes the slave is actually one degree higher than the master, which is a first in my chassis!), and the -new- master only hit 58C in GTAV. This has been with the Aggressive fan preset in XOC both times. Clearly my current master is much more parsimonious with power draw compared to the slave. They both reach the same clocks, but at different power/heat costs. As it stands, the leakier GPU needs less voltage to match the more power efficient one, even at stock clocks. The leaky chip periodically hits its voltage limit to stay with the Master, which is always at its voltage limit under load.

Even though both GPUs "are the same", and are both cooled in the same manner, one is much more suited to Water cooling, which would ultimately yield a higher max OC once temps weren't a factor, and the other is a perfect candidate for air, but likely has less max potential, if I were seeking it over out of box perf.

Attached a pic for context:

so it seems 81 is definitely out of band. i will try with the case side open for a couple of days with the slave bios and see where that goes.
 
i do have a 960 in the case as well but there is about 3/4 inch between the 2 (2 unused slots in the middle).

I should have mentioned, that since GTAV doesn't really tap the power potential of these cards, it wasn't the best example for me to give, but its temps were ones I remebered off hand. I went back to some of my logs, and in SuperPosition 8k, my 'old' master reached 83C! But the new master only hit 74C, and in both cases, my 120% power limit was reached. So though the 80s is a little high for a game, if you are running without an implicit or explicit frame limit, it is possible for these cards to get there.

Case air flow matters A LOT with this card. I thought I had a bad card hitting those high temps on 85 percent fan speed, but as soon as I reconfigured my case side panels and placed some intake fans on the side blowing directly at the card temps dropped dramatically from 75-80C at 85 percent fan speed to mid 60C at 50-60 percent fan speed. So much quieter and stable now!

Fair point, I have my sidepanel 200mm fan as an intake as I noticed the temps were better on the motherboard and GPU in general than sucking the air.
 
Don't know whether my friend's HAF X is doing the same, however he has planted two FTW3's in SLI (with space between), the case is inside a desk that is enclosed from 3 sides and him blocking the airflow too.
 
The temperature was 27,6-28,6°C ambient, both GPU's on the aggressive fan profile provided by Precision XOC, the temp of the hottest card maxed out at 75°C while the 2nd (bottom) card sticked to max 66°C.
Likely a fan speed of about max 90%~ on the first card and 75%~ on the 2nd, the cards were fully utilized in GTA V.
 
Not very bad results I'd say for non-blowers in SLI.

Mine is running in low 80s with 75% fan. Not using precision (yet). Stock bios and settings. Well ventilated case. 

ETA: Looking in my case, only one fan is spinning. Do I need to run precision to get the other 2 spinning?
 
ETA2: Installed precision and aggressive curve, working better now. 2 fans spinning but target temp is 84, so I assume third will spin up if it gets near there. Running much better now. I'll have to mess with precision to set it to my liking.

To get the third fan running all the time just switch to the slave VBIOS. It has really helped other folks whose FTW3 ran toasty.

Cool beans, thank you. It's running in the 50's now playing PUBG on master bios so I'm good for now. When I have time, I'll play with it and see what this card is really capable of.

i removed the side cover of the case (which has a 200mm intake fan right in front of the gpu), switched to slave bios and use evga precision to rate limit the card to 60fps (my monitor is 60hz) and now the card idles at about 27-32 and reaches 60 with gaming.
 
gonna airblow the dust outta everywhere, reroute some cables that may be blocking the lower intake fans and then gonna test with side cover back on to make sure just slave bios + frame rate is enough to keep the temp down.

im using the stock fan curve for memory and power. GPU i set mine slightly higher at 50C it goes up to 60% fan speed and at 60C it will go to 70% fan speed. in BF1 gaming for a few hours it wont go past 59C, sometimes 60C is the highest I've seen so far. The power and memory temps during gaming are around 64C ish. Idle is between 34-39C
