Install and open NVIDIA Control Panel or a GPU monitoring tool
Check current GPU temperature, fan speed, and fan RPM
Run a graphics stress test or benchmark
Observe whether the fan speed increases as temperature rises
Listen for abnormal noises, grinding, or clicking
Verify both fans spin if the GPU has dual fans
Set a manual fan curve or fixed fan speed in a monitoring tool
Confirm the fan responds to manual speed changes
Stop the stress test and confirm the fan slows down as temperature drops
Check for fan wobble, vibration, or intermittent stopping
Inspect the fan blades for dust, obstruction, or damage
Test the fan at different load levels to confirm consistent operation
