try to swap the entire cooler with the good msi armor see if the problem follows the cooler.
Thanks for this!
I know it's an old thread (found searching on google) but I had a couple older cards laying around that for some reason ran extremely hot no matter what I did. I tried the usual things like reapplying thermal compound, cleaning dust out, running super low voltages, etc.
After finding this I swapped the entire heat-sink cooler with another that ran fine and it worked. Until coming across this post I would have never thought the cooler would be the problem, as its mainly a hunk of metal with two fans attached, which in my case the fans were good.
So is it the liquid inside the little tubes that leaks out or what? I might try my luck on eBay and buy some parts-only GPUs for the cooler portion, but how to know if they are good?
yes might be liquid inside copper pipe leaked, but i dont think cause to much for rx 470 card which is low power gpu, might be some bent in mounting and die not connecting evenly in heatsink
this happen on many vegas gpu. trying to replace with new heatsink to costly for gpu already fall in price
