So I had the idea of going to a hybrid cooler on my FTW3 Ultra not because my temps were bad but because I'd be able to use a quieter fan.
 
Went through the process without a hitch. There was an ungodly amount of thermal putty in my card. Like a LOT.
 
Either way, memory junction temps are considerably higher on the hybrid cooler. I've gone from 88-94c under load to 98-102c+
 
Any ideas? I realize the hybrid kit isn't really designed to cool the memory any better but I didn't expect worse. Do I just need to go back to the air cooler?
 
Yes, I remembered to remove the stickers.
 
Thanks!

    Same issue on my 3080. Exactly the same. About to go back to air cooling.

    Yeah is this to be expected? I've even swapped out the stock thermal pads but my VRAM temps on the hybrid seem way worse than people are reporting on air cooled versions...

    My 3080 XC3 with the hybrid kit fitted doesn't get memory temps above 85 when gaming (reaches 96 if i'm mining). Not sure what they were before on the air cooling though.

    I don't have the hybrid kit, but I remember hearing there's a VBIOS flash involved--did that go ok for everyone?  if not, see: https://forums.evga.com/3080-FTW-Hybrid-Kit-Install-m3177119.aspx#3178112 it has 3090 VBIOS linked in there also.  Also, don't know if this applies for anyone but PX1 1.1.8 auto flashes to RBAR BIOS IDK if there are different RBAR VBIOS versions for the hybrid kit or not. Doubtful since there are several of you with same issue it's bad placement of thermal pads--you can lock fan 100% temporarily to see what temps do for comparison get maybe a little better feel for where you're at if you haven't already(?)  Can't think of what else it might be--GL!
