Turning up fan speeds is only going to create noise and at those temperatures if the fans you have already aren’t doing the job then you need to look at dissipating the heat in other ways, I don’t know what tower case you have but gaming towers have a lot more venting holes for the heat to get out ( if it’s an old or inexpensive tower you can drill extra holes in the top ), you can also add more or larger fans and even liquid cooling if your really thinking about getting serious but then you would also need a better tower to accommodate that.
