You can use Ubuntu as it works well for what you are trying to do.It is not mining specific but it can easily be made to mine like I am doing at home with my 2 x GTX 1050 ti,and for the card that runs at 82 degree Celsius it is a small fan factor which is running inside my Z workstation that is why it stays 82 degree all the time.
You just download the specific miner,in my case is T-rex because I am using Nvidia cards only at my home workstation.You edit the script files with your wallet and then run them with the command below for example to mine ETC:
./ETC-2miners.sh
The latest version of Ubuntu automatically detect your cards most of the time so I think you should have no problems with it.
82°C isn't safe to say the truth, work on the thermal paste and thermal pad atleast to run the cards at lower temp, or run on hiveOS and downclock to use low power which will reduce the GPU temp effectivelyYou just download the specific miner,in my case is T-rex because I am using Nvidia cards only at my home workstation.You edit the script files with your wallet and then run them with the command below for example to mine ETC:

Or just to use a pushing fan because it seems to be a RIG so for sure, all graphic cards are close to each other.
The last time I had this kind of t° on a graphic card, a flame appeared and burnt a component of the card...
This is your fault. I have a rig with a RX570, this card running with 87C degress for over 1 year know, nothings happen. Cards can run with up to 120 degress without burning. Newer cards like the 3090 have mem temps up to 120C stock.
It is running in 96 Degree now,I don't know how long it will last but I think it is a problem with the temperature sensor as the fans are running normally on the card,anyway it is not a rig,it is my home PC and nothing has happened during August which was a really hot month in here,now that the temperatures are 23 Degree Celsius I don't think it will start a fire,maximum it will die out as a card.As you have seen here MSI looks like a really strong brand that is supporting this temperature since August.
82C degress is to hot for an 1050ti, i have one without a fan an it is running at 65C while it mining. Change the thermal paste will help.
