Yes, those temperatures are good. You could tweak the fan curves for the case air flow with Alienware Command Center if you wish to shave off a few more degrees.   AWCC Manual 
Recently I bought an Alienware Aurora R12 and it has been pretty good so far. The only problem is that my cpu is much hotter then my gpu. On my gpu I get 30 to 35 degrees idle and 40 to 55 when gaming(higher when playing pretty intense games). On my cpu though, it is 45 to 55 on idle and about 70 when playing games (higher when play more intense games of course). Is this normal? It is water cooled btw   Specs: 11th Gen Intel® Core™ i7 11700F RTX 3080 38 GB of ram  
Aurora R12, are my temps normal?
