Since my last thread: https://forums.evga.com/GTX-1080-Ti-FTW3-HYBRID-GAMING-issues-m2797660.aspx 
I've RMA'd my previous card and got a replacement which works better, no more crashs or high temps.
 
But now every X days/reboots the pump speed (or so I think) stops working and I have to open my case and reconnect the little connector from the rad/gpu to restart it and get my temps back in order. Might I add that the little connector seems very fragile for such an expensive product.
I can clearly hear/see when this issue occurs as my temp in XOC go up to above 50c in idle/youtubing. And the fan makes considerably much more noise due to the heat. Which doesn't make sense, because normally it's only around 24C-ish.
 
Does anyone else have this issue? Or know why this happens? The case nor anything around it ever moves.
 
 
Edit: you can slightly hold the tubes and feel very little vibration in comparison to the working solution where it vibrates a whole lot more.

What program do you suggest to otherwise readout the sensor? I've got HWinfo64 installed which has always been good to me and doesn't have any controlling functionality.
Other then that I have CAM usually running but shouldn't be needed to run and no other programs that can control or read sensors. I will keep that one closed just in case.
 
Thanks for the advice I'll give it a whirl.

I do have Corsair Link installed but it shouldn't be running, I've disabled all the applications and just run SIV to check on things if needed.
 
I will report back if the issue reoccurs.
 
Edit: does that mean HWinfo is safe?

So far after days not running any monitoring software the problem seems to be away, but it might reappear. Wanted to update the thread for people having issues in the future. If it stays away I will revert to the programs running again and see if it still happends.

I'm running a bunch of duplicated monitoring software on my system the same time, including HWinfo64, MSI Afterburner, Coretemp, Precision XOC, Latency Moon, some Corsair software like Link, CUE and bunch of Asus software like Sonic Studio, RamDisk. They cause no issues with the pump, the pump isn't affected by these software installed on your system, it runs on its own once it gets the voltage.

Why are you running all that at the same time?  I guess those prior issues you had with Precision are fixed? I have Sonic Studio for the Centurion headphones and use AB for some mild overclocking.

thats nice you like to risk the stability of your system like that, most people prefer their system to not have the risk of suddenly going black screen or a pwm polarity inverting.

has nothing to do with stability, everything to do with mutex collisions.

Anyway, do you know control variates method? I believe you can achieve the same understanding without a problem. But don't dig too much about the word. These Asetek pumps are made to run full speed, you can control it with motherboard, maybe, with 10% difference in rpm. But pump stopping spinning is something else.
 

So this issue happened again, PC worked fine during the morning. Booted it up at night and no pump flow, had to replug the cable and the issue seems to be resolved after several reboots.
 
Why is this happening? There wasn't any software running.

Time to RMA the the GPU.

Again? Why is this such a bad batch?
 
I contacted support if they can help me with anything.

You can thank asetek for making crap pumps. Until their license/agreement whatever you wanna call it is up your stuck with asetek from any hybrid cooler make or all in one make as well.

Yeah learned that from GamersNexus, really sucks. They are not that bad pumps, but why license it and just be a bothersome.
