GPU Fan
A dedicated cooling fan for the graphics card on gaming laptops. GPU temperatures above 85°C under load, grinding noises during gaming, or a fan stuck at 100% are all warning signs.

- People Also Ask
Gaming laptops with discrete GPUs typically have two fans: one cooling the CPU and one cooling the GPU. The GPU fan is dedicated to keeping the graphics chip within safe temperatures during gaming, 3D rendering, and video editing.
A failing GPU fan affects gaming performance specifically — the CPU may continue performing normally while GPU tasks degrade.
- Grinding or rattling noise specifically during gaming
- GPU temperatures consistently above 85–90°C under load
- GPU fan stuck at 100% constantly even at idle
- GPU fan showing 0 RPM while the laptop is hot
- Game performance dropping suddenly after 15–20 minutes (GPU throttling)
- Laptop crashing or restarting during gaming sessions
| CPU Fan | GPU Fan | |
|---|---|---|
| What it cools | Processor (CPU) | Graphics card (GPU) |
| Active during | All tasks | Gaming & GPU workloads |
| Present on | All laptops | Gaming & workstation laptops only |
| Failure effect | Overall performance drops | Gaming performance drops specifically |
How do I know if it’s the CPU or GPU fan making noise?
If the noise starts specifically during gaming, the GPU fan is the likely culprit. HWiNFO64 shows each fan’s RPM and temperature separately, making diagnosis straightforward.
What GPU temperature is too hot for a laptop?
Consistent temperatures above 85°C indicate inadequate cooling. Above 95°C the GPU will aggressively throttle. A thermal service (fan clean + repaste) is warranted if you’re seeing 90°C+ regularly.
Can a gaming laptop work without its GPU fan?
Not for gaming — GPU temperatures will hit critical levels within minutes. For basic tasks that don’t use the discrete GPU the laptop may function, but gaming is not possible safely.
