You can control temp of the gpus, to avoid and extra hot.

--tstop 75 --tstart 55 --tmode edge   -->  will mine until GPU arrive to 75C, then will stop until GPU is 55C to continue mining

--tstop 96 --tstart 72 --tmode memory  -->  will mine until Memory arrive to 96C, then will stop until Memory temp is 72C, but that is only possible for Navi's

If you want to put 2 wallets you should run 2 instances of lolMiner.
