Improved Fan & RGB Control for Gamers

Addressing GPU Overheating: The Importance of Effective Cooling

In the realm of gaming computers, one enduring challenge persists: GPU overheating. This issue often arises due to a fundamental flaw in many systems: the fans primarily follow the CPU sensor, resulting in an ineffective fan curve or insufficient cooling, particularly for the GPU, even with a quality cooler in place.

The consequences of GPU overheating are significant, leading to reduced lifespan and performance degradation, especially in GPU-bound scenarios. Surprisingly, the solution lies in a simple principle: fans should always prioritize cooling based on the hottest component, typically the GPU. However, this fundamental principle is always overlooked, especially in prebuilt systems.

Prebuilt systems often exacerbate the problem by opting for poorly ventilated cases, intentionally designed to restrict airflow. The result? A veritable hotbox that significantly impacts component lifespan, cooking the GPU to an early failure.

Mr. Robot recognizes the critical importance of effective airflow. My systems are meticulously crafted to deliver unrestricted airflow, eschewing solid panels that impede cooling. Each system undergoes manual tuning to ensure consistent and efficient airflow while minimizing excess noise and dust collection.

However, it’s essential to acknowledge that certain case and component combinations inherently pose challenges. Some configurations may inevitably be loud, and detuning them risks overheating. This is precisely why I meticulously select part configurations to avoid such scenarios, prioritizing performance, longevity, acoustics, and your wallet.

CORSAIR AND NZXT’S SOLUTION: APPS

For users with NZXT or Corsair CPU coolers they can set their coolers to follow the GPU sensor using the NZXT Cam or Corsair iCue software.

However this is limited to a single sensor for control, which creates a potential for overheating of the component not being monitored in non-gaming scenarios.

  • RGB: Adjust RGB settings in BIOS, have no control in Windows to avoid apps. Many boards have RGB controls in BIOS.
  • Fans: Utilize the motherboard fan headers for connecting all your fans.
    • If you find yourself short on fan headers, consult your motherboard manual to ascertain the current limits for each header. To determine your motherboard manual: Read More
    • Calculate the load of the fans you intend to connect by multiplying volts by amps to determine the wattage.
    • This precautionary step helps prevent overheating or damaging the PWM headers.
    • When using PWM splitters, exercise caution and ensure that you distribute the load evenly and within the specified limits to avoid any potential issues. If you overload a header, it typically cannot be repaired without board replacement.
  • To establish the gaming temperature range for your CPU and GPU, conduct an intensive gaming session while monitoring temperatures using tools like nVidia FrameView or HwInfo64 with logging enabled.
  • Engage in a gaming session that pushes your hardware to its limits while still remaining playable, allowing you to observe peak temperatures.
  • Make sure to record the temperatures throughout the session to capture fluctuations accurately. This method provides valuable insight into the thermal performance of your system under gaming stress, enabling you to determine a suitable fan curve for optimal performance and stability during gaming sessions.
  • Adjust the fan curve(s) accordingly in the system BIOS in a manner that maintains consistent fan speed throughout the minimum and maximum CPU temperature range observed while gaming.
  • Set the observed idle temp to 0-20% fan speed to limit dust collection.
  • Set a loud fan speed to below your CPU’s TjMax temp to signal overheating with noise. You can find this information at the appropriate link below for your CPU brand:
  • Intel ARK | AMD ARK
  • To ascertain the minimum fan speed without adversely affecting temperatures, gradually decrease the fan speed and monitor gaming temperatures. Once you notice GPU temperatures beginning to rise, it indicates that the fan speed has been reduced too much. At this point, adjust the fan speed back to the previous level.

In table above, see this example configuration of fan curves, these settings allow for total silence at idle with no fan speed noise changes while gaming for a CPU that idles at 30C and games between 50-60C. While gaming, the system remains cool & silent with consistent fan speeds. Each configuration is unique so do not copy the above example.

THE NO BLOAT APP-BASED CONTROL ALTERNATIVES

Avoid the manufacturer bloatware in favor of these open source alternatives for maximum system performance, cooling efficacy, and lifespan.

Dynamic Lighting RGB Control on Windows 11
If supported, a motherboard BIOS update will enable this feature automatically. This is the best option, if available.

OpenRGB
If your motherboard doesn’t support Dynamic Lighting and you don’t want to use the manufacturer bloatware to control RGB.

FanControl
You can use multiple temperature sensors to control the fans with the Mix feature. No matter which component is getting hot, your fans are able to respond appropriately.

For setup tips, use mix and see the video at the bottom of this page.
