repasted my 3080, thermalright heilos from aliexpress seems to work okay.
UPSIREN Thermal Putty UTP8 was so annoying to apply that I wished I had went with pads instead. I used an entire 50g bottle and it wasnt even enough for all the pads, the pads I removed weighted around 32g

average gpu temps went down a bit
The hotspot temps went down significantly from earlier
memory junction temps are relatively high so I wonder did I paste them poorly but its within limits
