just wondering what are the normal operating temps (under load).
 
i slightly oc'ed mine to 2044mhz with 5250 memory. i'm hovering around 80~82 degrees under load. Since installing this card, even my CPU temps went up slightly by about 3-4 degrees.
 
what is the max temp the card can take without long term damage?
 
what are everyone else's operating temps under load?

Those temperatures sound about right with a heavy overclock on the card. You can always make a custom fan curve for the card in PrecisionX OC to allow the fans to spin faster to dissipate more heat. If you are seen increasing in the CPU temperature as well, then you may want to insure that your case has good airflow so that the heat generated by the card is removed from the system. Realistically the life of the card will not be affected unless the card is running in the 90C+ range.

First of all, thanks for the fast response.
 
as far as case having adequate airflow........
 
i'm using a HAF 932 with this config:
 
Front = 230mm fan blowing cold air into case
Side = 4 x 120mm fans blowing cold air into case
top = 230 mm fan blowing hot air out of the case
Back= 140mm fan blowing hot air out of the case
 
 
maybe i should change the side fans to blow hot air out instead of cold air in?
 
 

Your system does seem a bit jaded towards intake.
Some experimentation might be helpful. I might try reducing the side intake a little or reducing the fan speed on some intake fans and see if it makes a difference. Not much you can do about the CPU rising a little. There is generally poor airflow in the gap between card and CPU cooler.

I configure a fan curve and my temp never pass 71C. I am between 55 and 65 most of the time. That new ACX 3.0 are better then the ACX 2.0.
The maximum are 95 C but don't recommend to get to that level.

Keep in mind stock clock is around 1600mhz and these come pre-overclocked so ur actually running pretty heavy OC on ur cards so that said yes ur temp is awesome with that OC.

could it be that my temps were at 80~82 because of the design flaw on acx 3.0???
 
i have since switched cases from haf932 to dark base pro 900.
 
Current airflow:
 
front: 2 x 120mm stock fans (the stock be quiet fans are pretty good)
Back: 1 x 140mm stock fan
top = corsair h115i with 4 x noctua nf-14 fans in push/pull config. this blows hot air out of the case.
 
Still seeing 80~82c temps.
 
i think there's definitelly something wrong with my ACX 3.0 cooler.
 
 

I think it's more likely that you have poor case air flow.
 
The CPU temps going up makes sense...here is why:
- You have the two intake fans bringing air into the case
- The ACX style cooler on the graphics card pulls air into the fans, and ejects warm air (that just cooled the card) into the case
- This warm air is exhausted through the back 140 mm fan and the AIO radiator fans
- Best case scenario is that 1/3 of the hot air volume goes through the back fan, and 2/3 through the AIO radiator
- You 4 fans (2 pairs) in push/pull...so it's probably more than 2/3
- The AIO radiator is drawing warmer air in...the lowest the CPU temperature can get it the temperature of the intake air into the radiator
 
The intake on your case is more restrictive than some.  More restrictive means that you need a fan with better static pressure.  Here are a couple of things to try:
 
1. Increase the fan speed on the AIO radiator to maximum (I know it will be loud).  Let the GPU do it's thing.  See if the GPU temperature drops (it should as you are pulling more air out of the case...and effectively lowering the restrictive intake).
2. Assuming this works, drop AIO radiator fan speed in 10% increments and find the sweet spot between noise and GPU temperature.
3. Assuming this works, get new intake fans.  Don't just look for fans with CFM...regular "case fans" will not work well with your case as it has a restrictive intake.  The fans have to have a good static pressure too.  The corsair ML series fans are good fans...they strike a nice balance between CFM and static pressure (I have 10 of them in my case).
 
If all else fails, get a case with better air flow.  My personal story:
 
- I had an NZXT Noctis 450 case
- Loved the look of the case
- My system always ran hotter than others reported (even the memory temperature...close to 50 C)
- I tried EVERYTHING...stuff was still hot
 
- About a month ago, I changed my case to a Corsair Air 740
- With the same components, the temperature of EVERYTHING dropped by at least 10 C (15 C in some areas...my memory has yet to break 37 C for temperature)
- And I mean everything
 
The moral behind the story...the Noctis 450 case looked cool, but was very restrictive for airflow.  I actually like the looks of the Corsair Air 740 better!

the thing is, i was getting same temps on GPU with a cm haf932 with excellent airflow. my old gtx 970 heavily oc'ed never went past 60c. But the gtx 1080 was hitting 80c on the haf 932.
 
my new case is showing 2c increase over the haf932 i've had.
 
if your observations are true, should i be hitting at least 5-10 degrees hotter?

It all depends on the case airflow.  I'd have to look at the other case...too lazy to do that right now - hehe.  I do know that your current case has restrictive air flow...I researched this one when I was looking for a new case.
 
Have you tried cranking the fans on the 1080 to 100%?  (i.e. are the results you are posting with the fans at max, a custom fan curve, or the default fan curve.)
 
- For my 1080 FTW, I have a custom fan curve that looks like this:
-- 100% at 80 C
-- 80% at 70 C
-- 70% at 60 C
-- 50% at 50 C and lower
 
The card runs folding @ home 24/7 in a Corsair Spec-03 case (CPU is air cooled in this case, 2 intake fans, 1 exhaust fan).  The card never gets above 65 C.  This is a "high airflow" case...the first step in the light bulb coming on that my Noctis 450 case had poor airflow.
 
If you have already adjusted the fan speed on the GPU, you may have a card with poor TIM application on the GPU (it happens).  If you are comfortable taking off the cooler (a handful of screws) and re-timing the GPU, it would be worth a try.
