Question GPU1 on watercooled 1080TI burning up after PC swap

NOTE: Measures are Celcius, data mentioned found in attached pictures

I recently swapped some components to a new build, and after doing that my GPU has been throttling to an insane degree.

I have an 1080TI FTW3 which I have been running in a custom loop for about 5 years now. It has always performed exceptionally and never experienced higher temps than 75 under full stress test. Now, after having swapped some components, the GPU idles at 50, but when i launch CS2 or any other game, it instantly jumps to around 70, and when I join an actual match, instantly jumps to 90-95, where it stays until I close the game. When looking at the board in Precision X1, it tells me that it is only GPU1 which has the issue, which leads me to suspect it is the thermal paste that needs replacing. What I don't get is how that can happen in the span of 8 hours when swapping components? My CPU which is also in the same loop runs perfectly at normal temps, so I don't suspect the new loop to have caused it. Any suggestions?

50C idle is really high for a water cooled GPU. Should be pretty much exactly what the water temperature is, and I doubt you have gotten it that warm.

Air bubbles trapped at the GPU fins? Or it is clogged up with debris.

Just moving it around and manipulating it could have caused the thermal paste to come apart if the mount wasn't particularly hard in the first place.

Certainly taking it apart and checking the interior of the GPU block is what I would do.

liquid cooling is prone to failure over time.
In time the mechanical pump degrades or fails.
It may accumulate debris or air will intrude through the fluid tubes.
Think 5 years. With a custom loop, vs. aio, you may be able to repair it.
What is not clear is why swapping some components may have caused the degradation.

5 years on thermal past is a long time. any slight move with the tubing that flexes the card could have cracked the paste which is now giving you bad temps.


What parts were replaced in your computer? custom loops should be drained and cleaned yearly, when i ran mine i used distilled water with PT Nuke and a silver kill coil in the res.

Yea I know, and first i suspected the new loop to be the cause, as I downgraded from 1x 360 +1x 240 rad to only a 240 rad, for now an i7-9700k and my GPU. And no doubt the loop is much warmer than usual, but my CPU does not climb at all in temps when my GPU spikes at 92-95 degrees, and I can play with this for hours and the CPU temp will remain the same. So, while the new loop definitely is not optimal for liquid temps, it cannot be the reason for the instant 90+ jump.

I cleaned the entire loop with mayhems blitz about 1 year ago, so i would not think there to be any debris. I had a filter in my old loop, which I cleaned to be re-sold and that contained no debris either.

Quoting my reply from above for clarification

For the past 5 years it was drained and cleaned yearly, and as stated in the quote, flushed with Mayhems blitz about one year ago. I have however never swapped the thermal paste, which i fully know should be done more often than 5 years - So while I still cant believe it to happen in a span of hours, it is the only reasonable conclusion to be the issue.

Paste does dry but it's not a problem by itself. When you do such moving of card, cooler can move slightly and brake contact with chips.
