I swapped the pads on the 3080 yesterday, back in the UK for 2 days so figured I'd swap them while the missus was out.
The stock Nvidia pads appear to be made from white tac and dog hair, they're beyond sub-par for the job, way was sub...
tbh I was a bit tired when I did it as been running around all day, but even with a quick pad swap I've knocked 18oC off of the memory temp as recorded by GPU-Z, GPU temp is still where it was (mid 50's), that's with a power cap of 65%, -500 on the core and +1000 on the ram, with that it was hitting 106oC on the RAM while I was away, now its running cooler I'll leave it as it is until I'm back from Greenland when I have a few days off before going back into the office so I'll see how far it wants to stretch its legs and how lucky I've been on the silicon lottery...
