Hey there...Just picked up a Gigabyte 5700 XT OC...Currently running 850 1300 (120 watts in Phoenix miner 5.3e software) and the mem at 1820...I got the mem temps down to about 88 on the highest card by forcing it to run at about 45% constant.   Problem I'm having is that I can't get a stable setup over 1820 ish on the mem...Which gives me about 52.6 mh.  I am running a rig that had an nvidia driver in it but did the DDU 2x.  Curious what your clocks are and what miner you're using.  Are you guys on Windows?  

Have you tried the Bios mod?  Appears the links to the 3.04+ flashing software on Igors site are dead...

@rdlduffy try a fixed 45-50% on the fans and see how it looks.

The mem temps I reported earlier were when running the card all at stock, in a case with not great airflow and mining on Phoenix miner. I've now put the card in my mining case which has better airflow and am running it with underclocked + power tuning. New clocks are as follows:

gpu core 1247mhz @ 836mv
mem 875/1750 (default) @ stock voltage

fan speed @ 67%
power consumption: 119w
hashrate: 50.5 MH/s

Using the above settings the memory stays at 90 degrees under load. I can get it down to 88 degrees by raising the fan speeds above 75% but the noise starts to become too loud. This is the best I can get on the memory temps on this card (gigabyte rx 5700xt OC) when mining. Given that I think these temps are too hot I don't want to raise the memory clocks any higher and I'm happy with hashrate and power consumption as it is.

As mentioned previously running the card under normal gaming loads the memory doesn't get near these temps with a custom fan curve so obviously mining is taking it's toll heatwise here. The GPU hotspot temps are 65 degrees so more than fine there.
