I built my PC about a week ago, and I've noticed that my GPU fans aren't working as I expected. They do turn on when I first power on the PC, but during long gaming sessions, like when I play Minecraft, they don't seem to activate even though the GPU gets pretty warm. What could be causing this issue?

I think you might be hitting the nail on the head. When running modded Minecraft, the GPU may not be working as hard as you'd expect. You could use monitoring software to keep an eye on temperatures and fan speeds in real-time.
Exactly! Most modern graphics cards have intelligent cooling. Run a benchmark like Valley Benchmark at high settings to watch the temps. If they get hot enough, the fans should activate. Don’t worry too much if they're quiet while you're gaming lightly.
It sounds like your GPU might not need to cool down during Minecraft, especially if it's not pushing the card hard enough. Many newer GPUs only spin their fans when they're under load, so try launching a more demanding game and see if they kick in then.
