I decided to retest it anyway.  I did have my rad fans at 100% (ML120's).  They are on a mobo header, so it shows up as zero in GPUz.


Is that an FTW3?  Power input only adding up to 293w




Yes, the 3rd 8pin isn't showing in the pic.  Total power is about the same though, that's why I have it set to 85% PL.  Unfortunately the 3080ti FTW3 doesn't expose the mem power for some reason.  Doesn't show up in GPUz or HWIinfo.  So no way to be sure that's quite the same.  Obviously not quite an apples to apples comparison with a 3080 and 3080ti, but I would think it would be fairly close.

HAHAHAHA. Hey everyone I just found out why my memory junc temps are 85-95. oops, looks like i need to order new pads and some paste.
 
Thanks for the clarification.
 
In my own defense I bought the hybrid kit used, it was cleaned and the instructions online didn't mention any paste there (as far as I can remember). I remember thinking paste should go there, but I didn't design it so whoever did probably knows better.


Well to be fair your temps aren't out of the norm for the hybrids.  There's a lot of pressure in that little area.  I'd wager that not using paste there is only worth 4c, 6c at worst.  I've done a stupid amount of testing.  For instance using huge heatsink on the back of the 3090 only picked up 4c reduction in mem temps.


UPDATE
I kept the stock pads, and hit the gpu die/core(?) with a higher quality paste. I then put thermal paste between the copper plates and wouldn't you know it my temps went down. Roughly -5degrees on the core, and about -25degrees on the memory junction   Crazy what doing things properly can do for you.
