What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
You can change a graphics card’s fan behavior only when its hardware and software support the control you want. Identify the exact GPU and card maker, use a compatible utility to adjust a fan curve or speed target, apply the setting, then watch temperatures and fan RPM under load. There is no universal click path, and a fan stopped at idle may be working as designed.
What to check before changing GPU fan speed
Start with the exact graphics card model, not just the GPU brand. Board partners can use different fan-stop policies, minimum speeds and supported utilities even when cards share the same GPU chip. Laptop GPUs can have different limits from desktop cards.

- Find the card’s full model name and whether it is a desktop or laptop GPU.
- Check the card maker’s support page for compatible software and whether the model supports a custom curve or zero-RPM mode.
- Record the current curve or identify the utility’s Reset or Default control before making changes.
- Use one utility to control the GPU fan at a time; conflicting utilities can override one another.
A fan curve links fan speed to GPU temperature. A target setting, by contrast, may guide an automatic tuning system without giving you a complete temperature-to-speed curve. Available controls depend on the GPU, driver and utility.
Choose a control method supported by your GPU
| Method | What the documentation supports | Important limitation |
|---|---|---|
| MSI Afterburner | User-defined fan curve in Settings > Fan; startup loading is also described. | MSI says its custom-curve method does not work for laptop GPUs, whose fans are preset in BIOS. Available choices vary by card. |
| AMD Software: PRO Edition | Manual fan tuning for compatible Radeon PRO discrete cards in Performance > Tuning. | The documented controls exclude integrated and mobile graphics and do not describe every consumer Radeon software generation. |
| Intel Arc Control | Intel confirms a customized fan curve feature for supported Arc products. | The support article confirms availability but does not provide a full click-by-click curve procedure. |
| NVIDIA App | NVIDIA documents a fan-speed target used as an input to performance-tuning algorithms. | This is not documentation of a universal manual temperature-to-fan curve. |
| NVIDIA NVML | Manual fan-speed commands are available through a developer/management interface for supported discrete GPUs. | This is not a simple consumer walkthrough; manual control requires temperature monitoring and can replace automatic management. |
Set a fan curve in MSI Afterburner
- Open MSI Afterburner and select Settings.
- Open the Fan tab.
- Enable “user-defined software automatic fan control”.
- Drag the points on the curve to set the fan response you want, then click Apply.
- If you want the setting loaded when Windows starts, use Afterburner’s startup option described in MSI’s instructions.
MSI’s concise direction is: “Adjust your graphics card’s fan speed by dragging the nodes in the fan curve.” The available controls can differ by card. MSI specifically says laptop GPU fans are preset by the manufacturer in BIOS, so this Afterburner method cannot create a laptop GPU curve.

Check fan controls for Intel Arc and NVIDIA
Intel Arc Control
Intel says customized fan-curve control was added with driver 31.0.101.4369 and Arc Control 1.68.4938.6. Intel’s support answer recommends installing the latest available driver and lists supported Arc product families. It confirms the feature but does not give detailed instructions for building a curve. The literal support question is “Can Intel® ARC™ Control Modify the GPU’s Fan Speed in Settings?”
Rank #2
- Supports 6pcs 4 Pin PWM Fans (Fans not included, Not compatible with 3-pin/2-pin fans)

- Package include: a 4 Pin 12V PWM Fan Speed Controller ONLY
NVIDIA cards
NVIDIA’s App performance-tuning announcement describes adjusting a fan-speed target as an input to its tuning algorithms. That should not be mistaken for a universal manual curve editor. For a temperature-based curve, check whether the exact card exposes one through its card maker’s supported utility or a compatible third-party tool.
NVIDIA’s NVML interface provides manual fan-speed commands for supported discrete GPUs, but it is intended for developer or management use rather than a general consumer setup. NVIDIA warns that users who take manual control must monitor temperatures and adjust speed accordingly; the interface can restore default control.
Why a GPU fan may be stopped
Zero RPM at desktop idle is not, by itself, evidence of a fault. Some cards stop their fans until temperature or power reaches a model-specific threshold. The card’s fan-stop mode, rather than a generic temperature rule, determines when fans start and stop.
Rank #3
- Fan Speed Regulator: This device is a 4 wire temperature-controlled fan speed regulator that allows for automatic or manual adjustment of fan speed based on temperature (℃) readings. It features a digital display showing both the current temperature and the fan’s rotational speed in RPM (revolutions per minute). The system helps maintain optimal cooling performance and energy efficiency by increasing fan speed as temperatures rise and reducing speed when cooling demand is lower.
- X100RPM: The RPM (rotations per minute) is displayed in units of 100 RPM, which allows it to accommodate and clearly show the speeds of high-performance fans, this makes it particularly suitable for industrial or specialized applications that utilize high-RPM fans. The maximum readable value on the display is 300 × 100 RPM = 30,000 RPM, ensuring compatibility with a wide range of fan types.
- 2 Control Modes: The device offers both manual and automatic fan speed control modes, giving users flexibility to adapt to various cooling needs and environments. This dual-mode system provides an ideal balance between user control and intelligent automation.
- Temperature Probe: To ensure accurate thermal regulation, the fan controller is equipped with a 42cm (16.54 inch) temperature probe. This probe continuously senses the surrounding temperature and sends real-time data to the controller, which is then shown on the digital display. The extended cable length provides flexibility in sensor placement, allowing users to position the probe closer to heat-sensitive components or areas where precise temperature monitoring is needed. Temperature probe parameters: NTC10KB = 3590
- Note: This controller only controls the fan speed adjustment controlled by a 4-wire PWM signal. The signal specification is 25KHZ 5V. It cannot control the speed regulation of 2-3 wire fans. The working voltage must be equal to the fan voltage.
For example, ASUS lists fan-start conditions above 55 °C or 100 W for several specified RTX models, and above 52 °C or 100 W for one listed RTX 3060 Ti example. The listed stop conditions are lower and require 0dB Fan mode to be on. These figures apply only to the models in ASUS’s table; ASUS notes that actual temperature and wattage can vary with configuration, usage, operating conditions and power-management settings.

- Save or note the original curve, or locate the utility’s Reset or Default control.
- Change one point or target modestly at a time, then apply it.
- Run a representative game or workload and monitor GPU temperature and fan RPM, not just idle behavior.
- Compare noise and temperature. Restore the default curve if cooling becomes inadequate or the fan behaves unexpectedly.
- Return control to automatic mode if you cannot confirm which utility owns the fan setting.
Do not force zero RPM or an unusually low manual speed unless the card’s own controls support that behavior and temperatures remain acceptable. NVIDIA warns that GPU temperature can rise to the point of throttling or shutdown, and its manual-control documentation warns that setting fan speed too low can damage the GPU.

Troubleshoot fans that do not spin under load
If the fans remain stopped during sustained load, verify the card’s fan-stop policy and its temperature and power readings first. Then check that the card is recognized, drivers are installed and no other utility is overriding the fan setting. If the GPU reports very high temperatures, throttles or shuts down, or a fan is visibly damaged, return the setting to automatic and contact the card maker’s support service.
Also check for obstructed airflow and dust. NVIDIA notes that improving overall system cooling, such as adding a case fan, can help when a GPU reaches its maximum operating temperature. A case fan does not repair a failed GPU fan or replace the card’s cooling assembly. If a fan or cooler needs replacement, the compatible part must match the exact graphics card; check warranty and support options before attempting an out-of-warranty repair.

How to choose the right approach
- Want a temperature-based curve? Use a utility that explicitly supports your exact card and exposes curve control.
- Have an AMD Radeon PRO discrete card? AMD Software: PRO Edition documents manual fan tuning within its stated product scope.
- Have an Intel Arc card? Intel confirms a customized curve in Arc Control for supported products, but its cited article does not provide detailed curve-building steps.
- Have an NVIDIA card? NVIDIA App documentation covers a fan-speed target; verify card-specific utility support for a manual curve.
- Have a laptop GPU? Check the laptop maker’s controls. MSI’s documented Afterburner curve method does not support laptop GPU fans preset in BIOS.
