One of the oldest issues with gaming computers is that the cooling fans follow the CPU and the CPU doesn’t get hot enough in games so your GPU ends up running way hotter than it should.
For users with NZXT or Corsair CPU Coolers that have utilized the ability to control their case fans as well, this isn’t an issue because they can just set their coolers to follow the GPU using the NZXT Cam or Corsair iCue software. This is how I configure all my builds.
For everyone else, (excluding systems that have their own fan management apps such as Asus Armoury Crate or MSI Center) I recommend Fan Control:

Gamers: set up a fan curve that follows your GPU
Creators: set up a fan curve that utilizes the Mix feature so it follows CPU and GPU
