Hello,
 
I had a question about my 1080ti sc2 hybrid, I was playing destiny 2 last night and experienced random FPS drops, and then my screen proceeded to stutter and turn back and on and off again.
I turned my pc off and checked the radiator and noticed it was burning hot, I didn't have any software to monitor temps sadly.
The main thing that concerned me was the radiator fluid seemed solid, does this happen very often?
Has anyone experienced this before?
Appreciate all the help.

I have no way to confirm this, as I have no taken it apart, but when i moved it side to side, it sounded like a clump falling from one side to another instead of fluid movement.
I have since installed cpuid and my temps have been rather steady, idle is 20-22c and under load its been anywhere from 49-54c.
I know airflow is not an issue, i have a corsair air 540 with 3 fans pushing air in and 3 pushing air out.
Was just curious if anyone else had experienced this.

That's strange to me as I have a corsair h115i for cooling the cpu, I am not sure why it'd overheat as destiny isn't CPU demanding.
I will continue to monitor my temps and post again if I have more issues.
Thank you for your help.

Run GPU-Z & CPU-Z & see what your hardware is actually doing
 
List your hardware, Nvidia driver, Nvidia Control panel settings & OS details
 
Radiator being Hot should indicate the fluid is flowing
 
What Case & fan setup do you use ?
