Is my GPU temps too high?

Quick question for people who hopefully have more knowledge than me. I have a reference RTX4080 Super with a bykski waterblock, my hotspot temps hit nearly 70 degrees c and I am wondering if that is normal? I have seen RTX4090 under water with much lower temps with a waterblock (my old RX6800XT at a similar power limit also is cooler). I do think that this particular bykski block may have tolerance issues as in order to get temps under 70 i've had to use a 3mm thermal pad on top of the gpu chip using the back plate to apply pressure to make a better connecton with the main block. There is a couple of pics showing how the thermal compund spread out before I used a 3mm thermal pad to apply more pressure, all the thermal pads seem to make good contact tho.

Information on my card:
GPU is a Inno3D RTX4080 Super X3, it was returned to OCUK for not posting, at this time I had not touched it and it was still on stock cooling. It was sent back to me with no fault found, I decided when it came back to me to fit the waterblock. The card ran well with pretty decent temps for a couple of months until I noticed that the hotspot was slowly getting hotter and hit a max of 94+ degrees c before I decided to take the card out and apply new thermal compound, after that it would post but would crash trying to run any game. I panicked a bit and in removing it for the 3rd or 4th time I knocked off a capicator and damaged some traces (that was totally my fault) I brought it to a local electronics engineer and he was able to fix the broken trace and replace the capicator, but he also saw under the microscope that there was a cap/resistor that was cracked and shorting to earth (this was on the top of the gpu right above the core and I think may have been my original fault before I even put the waterblock on it), that was also replaced, the card has been working flawlessly since and even takes a bit of an overclock, but I am curious about temps.


Any help or info would be appreciated. Thanks in advance.

70°C on the hotspot is fine and your thermal paste application and pads look good to me. Going forward I would suggest keeping an eye on it considering its... adventurous life.
