Hello all, just wanted to see if I can get any input about a potential high temperature issue I'm experiencing. I noticed today the red thermal LED for the power come on today for the first time since I built my PC back in May so I figured I'd fire up Precision X to see what kind of temps I'm getting. I noticed that the GPU temp would stay in the mid to low 70s, the Memory temp would be in the mid 70s as well, but the Power temp was reaching around 83c at max after about 15-20 minutes of playing the Witcher 3. While I don't have any temps from before today I can say that I've never noticed the power LED turn red (83C or higher) but then again I don't tend to look at my case much while gaming. Does this seem to be an abnormal temperature anyone? The card is not overclocked and I'm using the default fan curve.  Current idle temps are GPU 33c, Power 35c and Memory 34c.  Any help/input would be great.
 
Specs of note: 
Cooler: NZXT Kraken x62 rad mounted in front
Case: NZXT S340 Elite w/ 2 120mm fans exhausting from back and top
Monitors: Dell S2417DG @ 1440p 165Hz as main, Crappy Samsung 900p as secondary.
 
I have also tried gaming with the panel off of my case and temps were within 1-3C so I'll assume it's not an air flow issue.

I am running the default fan curve and while I agree the GPU and Memory temps do seem normal I'm just slightly concerned with the Power temp hitting 83c as that doesn't exactly seem normal. Like I said, I've never noticed the temp led hit red before today. This could be normal for all I know I'm pretty new PC gaming.

Power temp would be the one to least worry about. VRMs are designed to run at up to 125°C. Microns GDDR5x modules should run up to 95°C and Nvidia's 1080 Ti is supposed (recommended?) tu run up to 84°C (please correct me if I'm wrong). Because of that I have the same custom curve for each of the fans but the one for RAM is shifted by 5°C towards higher temps and the one for power-VMRs is shifted again by another 5°C.

I figured it's not much to be worried about, just seemed odd to me as I've seen other posts pointing to temps in the 80s as somewhat abnormal but as stated, my VRM and PCB aren't hitting anything higher than 75C. Seems the Red LED was what was throwing me off.

So, essentially that means 91c is the max rated for the power on the 1080ti?

91c is for the gpu chip itself. Power = vrms.

Got it now, last question for you, in precision, the temp target is set to 84c by default before it'll begin throttling the card. That's for the GPU chip itself correct, nothing to do with power or even memory?

Correct. The card is actually dynamically adjusting when it hits 84c. Throttling is completely different.

Perfect thank you! I ended up giving DOOM a run through and after about 10 minutes my temps were about in the mid 70s, and in heaven ultra with all the settings up it managed to stay in the mid/upper 70s (two benchmarks) so I guess it's just the Witcher being demanding.

I have the same case. I was able to lower my temps by 10-11c. The way I did this was, I noticed under the card I was building a small campfire. I see you are using the NZXT kraken x62. I am pretty sure you have it blowing the air out. If you redesign the case so that the air is blowing in, under the GPU, there is no campfire being built there. It will cycle cool air. ALso I would recommend using a min of 65% fan speed.
With s340 and x62 on the right side of the case, the front. Mount the fan to blow in the case.

That's how I have my case/cooler configured already as the S340 only permits a dual rad to be used as intake . Honestly, since the posting of this I found it was only PWR4 that was getting warm due to its proximity to the chip itself and it hasn't gone anywhere above 80c even on the most demanding titles. Only other solution I could think of to further lower temps is to replace the 120mm exhaust fans the case came with, with 140mm fans but I'm not too concerned anymore.

If you redesign the case so that the air is blowing in, under the GPU...

Are you seriously recommending blowing the warm/hot air inside the case to warm up the rest of the system instead of preventing it from heating anything else by blowing all the possible heat outside and just getting another intake fan?

I think that is the way you want it to be. If you are heating up the inside of your case you are blowing it out the rad for your liquid cooler, that can cause very high cpu temps, also then you are creating a very hot place under your gpu. I think it is better to blow outside air into your rad, and under your gpu, this way your gpu fan cycle cool air and your cpu stays cooler.

Yest this is my setup and it works really well, there is youtube video out there where a guy did tests with different setups and with a "blower style", https://www.youtube.com/watch?v=xNAMxZgvves
 

Just one more note.
PWR temps will, in most of the times, be higher than the GPU/Mem. temps.

If this is a concern for one that uses the FTW3, it's recommended to make a custom fan curve (GPU/Mem. might be the same curve, but PWR would be nice to be a little bit more agressive to keep it cool, as stated by the members in this thread ).
