This is in my custom water cooled living room PC. I just finished upgrading from a 980 Ti to a MSI Gaming X Trio RX 6800 XT. I'm running this exact same card on my main battlestation PC with the exact same Alphacool water block. I'm also running similar loops on both with all EKWB components. The battlestation PC has GPU idle temps of ~32C with hotspot at ~37C. After 10 minutes of Heaven Benchmark it's at 53C and hotspot is 63C.
The living room PC idle's roughly the same at 30/35C but then tops out at 60/90C in Heaven. It initially hit 75/105C in Heaven and 3DMark but then I took the back plate off, tightened the 5 screws holding the water block around the die, then reinstalled the back plate and got the 60/90C temps. I initially had the screws only snug according to the instructions. Not hot enough to thermal throttle but I knew the water cooling should've performed way better. I used Arctic Silver 5 paste instead of the included Alphacool paste and evenly spread it across the die according to the instructions.
The living room PC's case is a Fractal Define 7 so it has a front door and sound dampening mats on the sides. It has 1x front 280mm rad with 2x 140mm intake fans and 1x top 240mm rad with 2x 120mm exhaust fans, 1x 140mm rear exhaust fan and an extra 140mm intake fan on the floor under the reservoir. Radiator fans are spinning just under "too noisy" threshold which is +/- 1500rpm. When I open the door temps drop by 6C.
By contrast the battlestation has a Fractal Meshify S2 with an open grill front and no sound dampening. It has 1x front 280mm rad with 2x 140mm intake fans and 1x top 360mm rad with 3x 120mm exhaust fans, 1x 140mm rear exhaust fan and an extra 140mm intake fan on the floor under the reservoir. Fans are spinning a little slower at +/- 1000rpm. I can't remember if I used the Arctic Silver or Alphacool or Thermal Grizzly paste on this card, it took a couple attempts for me to get it right so I was trying different brands.
Anyway I would really like to avoid the huge PITA ordeal of reapplying thermal paste if I don't have to. I know 60/90C leaves a ton of breathing room until thermal throttling but it still seems high to me.
