Agree with all others do not mess with ANY bios if you have no experience in doing it
It looks easy but small mistakes can lead to absolute failure and possible brick your hardware.
Yes i have bricked a few times some of my hardware and to be honest i hardly see any reason todo that anymore either unless your a hardcore overclocker

But even they hardly ever use it anymore as the super tools from this era makes fixing it as easy as eating pie

Make a profile and save that so in case you get any change you load the profile and poof all is back at what you made it do.
These cards are really able to handle the heat and just throttle a bit when they become too warm to its taste.
I got a "ASUS TUF RX 6800 XT GAMING OC" myself and cranked the speed a bit down even though it does not even hit 110 C.
Now having 6 fans does not mean that your airflow is good, in fact it could be a mess as you need to use any smoke to see if you flow is good, most people put in tons of fans and have a total blocked airflow i use the little stick with the smell
I admit i forgot the name of them but have a huge pile of them, with that i test how my airflow is in my case
So assuming that (232 billion) fans make it cooler is absolute a fail thought
So to be honest i see no result in performance at all with the profile setting i did in Adrenalin in any of the games and it stays very cold for this kinda card now.
I run most of my games with max settings (aka 4K) with my dual 4K monitors except when there is a insane amount of glowing bs happening in the games i play

It runs so good that i really do not find the need for the XFX 7900 cards at all
