I didn't like how I made my first water loop, so I remade it. Noticed some debris in the block so I had to take the block off to clean the channels and remount it.
GPUz AND Aida64 can read everything just fine except PWR5 which stays pegged at 125C. Which I highly doubt.

Card seems to be working just fine. I do need to drain the loop in a few days before the final coolant, so maybe I'll pull it back apart. Could the block be touching something? Is it some software bug? I will say I went from Kryonaut to Conductonaut, but it is not my first time. I used it in/on my delidded 6700K which lasted 7 years overclocked to the moon. I would assume if I applied to much, the card wouldn't work at all if it was touching one of those small caps sitting around the die. Of course I was super careful the entire time but I doubt it's the TIM application. I'm leaning on shorting out PWM5, or I broke it.
I tried uninstalling Precision and reinstalling. Still reads 0C, when it should be showing everything just fine except PWR5 at 125C.
 
If someone at EVGA could show me exactly where the PWR5 sensor is located that would be a huge help in trouble shooting.
 

Check the temps using hdwmonitor as well.. maybe even gpu-z can show all the sensors as well.

No damage to the pads after reinstall of the block twice?

Welp I'd say use it.. if it's pegged at the same temp then clearly a defective sensor.

I wouldn't rma the card for it.

Pulled block off card, reassembled. No change. Didn't see anything missing on the PCB so I am leaning towards a software issue. Maybe I'll install the OS tomorrow on the new M.2 tomorrow and see if anything changes.

If you got two apps showing you out of wack values, I think it's fair to say its most likely hardware related.

Yeah like a said.. forgetabouti. Worry about it when the time comes to put the original cooler back on to move it to a 2nd rig or sell it.

Makena note of it and drop it in the box and forgetabouttit for now.

I'm now thinking about the future when I replace the card, as it will eventually end up back on air in a backup system. I'm just wondering if I should take a chance with them exchanging it, and having to clean the terrible thermal puddy off again, or if they can fix my issues. I have my loop torn apart for modifications and the card is back on air with a thermal pad kit I bought off Amazon.
Fans one and two run at 100% with three being the only one I can control. So the rig is screaming loud like a C130 on takeoff.
At the time I originally started this thread I was just going to do what AHowes said. Worry about it when the time came. Well, now that EVGA is as of at this moment, not in the GPU market. I'm worried that by the time my extended warranty ends Feb 29' that they would no longer be able to repair or replace which is most likely when I would do this. Guess I could just maintain a second water loop, but I would rather not.
 

Erm... if you've already physically damaged the GPU, you've already voided your warranty.  Purchasing an extended warranty does not change the conditions under which a warranty request can be rejected. As far as I am aware, EVGA does not do any repair services at all.
