I use the EvenMorePower5700XT++ and using the stock cooler on my new 5700 XT Just don't go crazy with with the voltage or power limit...however the worse it will do is be very loud, throttle or just crash when it hits the limits the card can do.
Got the block on the way, so i'll just wait. Rightnow, Auto Undervolt in Wattman works great.

I did it (What OP asked for)

I flashed the 50th Edition bios into my 5700 non XT.
Note that I have the reference design from MSI and that one share the same bios with many other 5700 reference.
Be sure to check that the BIOS you flash over have the same memory support... Just to be sure.

Also I do not have Windows.
And that manipulation of flashing a 5700 50TH BIOS in a 5700 cause my Linux kernel to dump a ton of IOMMU error and the card did fail to initialize.
But disabling the IOMMU in the BIOS made it work just fine. My 5700 non XT stay at 1980 Mhz almost all the time when i'm gaming, thanks to my overly abusive cooling setup.

Yo, new to the forum, I flashed a Sapphire Pulse RX 5700 to pulse RX 5700 XT yesterday, temps went insane & had to undervolt to around stock RX 5700 XT speeds(since the XT pulse is factory OC'd) to get it running more sensibly, got a cooler upgrade on the way though, since I plan to push this thing xD.

Ran some Heaven Benchmark tests here:
Stock, no undervolt;
After a bit of tweaking;
Stock RX 5700(no flash) vs flashed undervolt: https://imgur.com/gallery/5GMptkC
