I've two cards that started acting up last Monday, and after all the usual suggestions, like cleanup, shake radiator, make sure it is well plugged, update bios, update drivers, etc. they still go to 90o ASA any load is applied.
 
I feel heat on the tubs, they feel like "working", both fans rotates ok and freely, but temps are out of the chart!
 
The thing that strikes me odd is that all screenshots I see around GPU Fan has numbers, and mine are zero (attached)!
But I swear they ARE spinning full power.
 
Any ideas?
They are 2 years old so not sure I can return them...

I was thinking about that, 2 questions though:
 
1. is it easy to DIY? Replace the thermal paste?

2. and the FAN zero RPM? Is that normal?

1. Yep, easy.
2. Most likely a software glitch. Try using msi afterburner, precision x1, or gpu-z to read the rpms.

Here is a shot with all 3 apps (HWiNFO, GPU-Z and x1) showing zero RPM, and XOC (replaced yesterday by X1) was also showing zero.

Ok, cleaned and reapplied thermal paste in 1 of them, same end result.
temps get to 90o really fast under load and thermal throttling starts...
 
any other suggestions aside from buying a new board?

Do you guys have any schematics for a water cooler open loop?
I was thinking about adding those 2 radiators a independent pump, would that work?
Does the existing dead pump (supposed) on the card would impede the water flow?

That GPU you are showing there is faulty. The clocks are completely wrong for being under load. GPU core is a idle clocks. If you have pump vibration and different temps on the hoses, I'd try redoing the paste again. However, the lack of the GPU boosting, does not bode well for the GPU.

I've 2 of those, and they behave exactly the same.
 
And the clocks go that low after the temps go over 90o.
Isn't that expected? Because of the thermal throttling thing?

As soon as I run my PC I see the GPU clock going all the way to 1,500 and the memory clock to 5,500.

I've just started having this issue with my GTX 1080Ti FTW3 Hybrid!!!!
 
It started overheating immediately upon a load on the card and I sent it off to EVGA since it was still under warranty. I got the card back and it was still doing it, but now I hear the pump chugging on air and it still overheats right away. They told me nothing was wrong with the card and they tested it for 2 hours. It is shocking they missed this since it was immediately making this horrid sound the moment the card received power.
 
I tested it in a different computer as well with the card in a vertical orientation as if it were in a test bench and the problem was intermittent but still happening (sometimes no grinding sound from pump but still spikes in temperature), whereas if mounted in a normal way that most cases would have it, the problem is immediate and constant.
 
I don't want to operate my computer on its side just to play games and have to worry about the game crashing when the intermittent chugging and temperature spikes occur at least once a minute.

Oh man!


I just hope they do not do the same with me!
It is already hurting to have to use my small laptop to work/code all day long...
I do not want to receive the same card back, I did tested on all ways possible, including clean windows reinstall on my own machine (another drive) and tested on another friend's computer, all with the same result.

The odd part is you have TWO with exactly the same problem at the same time. My first AIO failed after ~6 months. Pump died. Bought two of the new revised model, so I have a spare. Still going strong on the replacement with a brand new spare in box.

This is how I mount my 1080 Ti FTW3 Hybrids ... bottom hose (suction) goes to the pump
 
 

Ideally, you should have both hoses on the bottom as suggested by the manufacturer. I also believe you'd have a bit cooler temps if you had more than just a single fan for exhaust, with everything else being intake.  Just from looking at the image. (I hope you don't mind the critique) Dual GPU AIO is usually kinda tricky as cases are not really designed with them in mind. I'd wager two Scythe AP-14's in push/pull would outperform the 5! you have now. Now sure how you believe one fan, is actually passing the volume of air of the other 4 preceding. It is not.

@ HeavyHemi
 
running Push/ pull & many spacers for that giant case
 
Inside front of case --> "first black spacer" is a gutted old fan as the hoses were on the tight side before
 
"donor fan body", clear spacer, Fan 1, clear spacer, radiator, Fan 2
 
That case is not sealed, glass panels do not touch frame or in corners .... plenty of room for exhaust airflow ... top radiator is "currently" exhaust push/pull .. (cause CPU temp is just fine)
 
See my Build log for AIO Folding
 
So we do not derail this thread ... all critique, questions & comments should be in my thread ... beside I have better descriptions, many more pictures & several closeups

Could be the coolant level or particulate (gunk) blockage issues .. do not know .. you say you hear the pump running
 
Try turning radiator clockwise 90 - with hoses on bottom position ... if the coolant is low this might help -- you mentioned PC on its side was better
 

I tried this after also giving what you said earlier another try and it seems to have fixed the issue. No sound and its cooling well, I guess it could have been air accumulating somewhere until it became a problem.
 
 Thanks for the suggestions!
