Update 17-07-2017:Precision XOC 6.1.11 has solved this issue for me, even though I have not tried the versions 6.1.9 and 6.1.10. Hello EVGA, I think there is an issue with the monitoring of the temperature of the GTX 1080Ti FTW3 on the sensor called ' GPU Power 5' in Precision XOC V6.1.6 and EVGA iCX PWR5 in GPU-Z 2.1.0 I have noticed the following: - The temperature of GPU Power 5 is raising under load beyond 45°C, then jumps towards 53°C, this temperature is shown as Power in the main Precision XOC window.
- The temperature of GPU Power 5 has reached atleast over 53°C+ under load, when I let the temperatures drop it seems that the GPU & Memory temperature drop quicklier than the temperature of Power does.
- The GPU & Memory temperature may have already dropped to 41°C~ and 45°C~ and nearly stopping the fans, but Power temperature may still be stuck at 53°C~, this also affects the fan speed.
- When the Power temperature drops below 53°C and hits the 45°C mark, it jumps towards 45°C~ directly, ignoring the temperature range of 46°C-52°C.
This doesn't seem to be right, it cannot drop this quickly that much on an instant, the fan curve then quickly adjusts to the reported temperature. While this is not a ground breaking issue I wonder what is causing this temperature reading issue and whether this is a global or an isolated issue. The only other monitoring software active is Asus AI Suite II Thermalradar & Speedfan 4.52. A custom fan curve is set to the same curve for all fans, screenshots can be seen below.

Looks like your card may have a lazy sensor.

Looks like evga has another bug to fix.
I tend to think this may be a firmware issue, and GPU-Z is just reading the same data as Precision XOC does which is outputted by the firmware on the card which reads the sensors. (atleast that's how I think it's set-up) If this is an isolated case with just my videocard then that's no big problem, but I just want the information to be out there, I wouldn't RMA over it. I think EVGA Precision XOC did update the firmware at the first time the FTW3 was installed (twice for odd reasons), so it's probably possible to update the firmware incase it's a global issue. My friend now has two FTW3's installed today, I could possibly ask him what the readings do if he's willing to cooperate, but others may report in if they see the same behaviour. He bought them because of me, he was still rocking an EVGA GTX570 and two EVGA 680 4GB Classifieds in two PC's, the GTX570 will finally be put to rest and the 680's will live their second life.  Edit: Ah a lazy sensor, well that is another possible thing maybe, though I would like to see confirmation if it's really just that or something more widespread. If that's true I hope it doesn't get worse.

At first I thought it was a bug, but then I was like it's happening with both precision & gpu-z, so it must be a lazy sensor. Does the issue get any better if you exit speedfan & asus ai suite?

Did you try a complete power off? I think there was a thread on tge 10 series forum that suggested cutting board power for 30 seconds was needed to reinitialiuze the mcu on the card.

Nope, just tested it again, however now it jumped from from 44°C to 53°C directly, and back from 53°C to 44°C even though there was barely any time for the GPU to cooldown between this temperature range, so something is acting funny here. ipkha

The system gets complete shutdowns and power removed every night, I have the card installed since 15 May, so that's unlikely to be the case.   Update: Tested it another time in GTA V, now I get a conflicting readings, the information shown in Precision XOC main window does not match what is shown in the HW Monitor window of Precision. This is weird. Here are some additional screenshots, compare the main window Power reading with the HW Monitor reading for GPU Power 5.     I really think there is a conflict with the hardware temperature readings. Update 2: By the looks of it it is currently looking at GPU Power 4 in the next screenshot below:
(yes my power/cpu settings/graphics are currently limited for less heat generation, room is hot enough)  The weird thing is when I look at the four screenshots I posted at the first update, is that it seems to jump between sensor readings of GPU Power 5 and GPU Power 4, I only just noticed this. I'm starting to get confused with what is going on, but I think it's a software issue.

Hopefully other people with icx cards will chime in.

I have let my friend test his two GTX 1080Ti FTW3 cards in SLI, both GPU's reported the same issues as my card does with Precision XOC V6.1.6. When GPU Power 5 on his cards went below 53°C they also skipped the range and dropped back to 44°C, each independently (because the cards are seperately monitored) I have noticed that at times GPU Power 4 is monitored instead of GPU Power 5 too in the main Precision window for power, this appears to switch sometimes between the two sensors, I don't know why. This has to be a software bug ( firmware of the GPU's) and not a coincidence, I hope EVGA will look into this issue soon. GPU-Z shows the same odd problems, so it has to be the firmware delivering the wrong information. Here's an additional picture, take notice of the Power temperature in the main window being the same as GPU Power 4, while GPU Power 5 is reporting weird temperatures rapidly.

Interesting. Hope it's just a firmware issue. Hope evga didn't release a batch of lazy sensors.

I confirm the existence of such a problem.
A lot of promotion and advertising of iCX technology should not allow this.
The request of the EVGA is to do something sooner.
This is not an excuse for the RMA, but can it be enough to make mistakes for the FTW series? Especially for a lot of money paid.
It strains and undermines the credibility of the brand.

Hi all new here to the forums, i have a gtx 1080ti ftw3 under water cooling and have noticed in the sensor tab in precision xoc v6.2.6 its reading the wrong sensor for the core of the gpu, how v6.2.6 is layed out sensor wise is
front of the card
gpu 1
gpu 2
mem 1
mem 2
mem 3
pwr 5
back side of the card
pwr 1
pwr 2
pwr 3
pwr 4
i've noticed that my card is recording the gpu temp using gpu 2 sensor which wouldn't be a big problem usually but this particular sensor is always 5 - 7 degrees higher than gpu 1 sensor which is the core its self, gpu sensor 2 is the surrounding area around the core, does anyone know if this is right, i've been overclocking the card and noticed the core temp which is sensor gpu 1 hovers around 39 - 40 degrees but gpu sensor 2 hits 48 degrees which makes the card throttle back a bit due the incorrect reading. has anyone else experienced this issue?, don't get me wrong my card still demolishes most games at ultra at 1440p

I thought that gpu2 is a sensor on the back of the board in the core zone.
In any case, gpu1 is a diode inside the core and it is the most accurate sensor on this board.
Just select it to display the temperature in XOC and forget it.

Yeah my bad was playing around with precision last night and noticed there was the ability to select gpu 1 in the main screen, have gone ahead and sorted out my issue, feel like such a idiot for asking but hey many thanks for your help :)
