Hi NZXT team,
I’d like to suggest an important improvement for your fan control system in the NZXT CAM software: the addition of a hysteresis option.
Currently, the fan curves respond directly to temperature changes without any delay or buffer, which can lead to rapid and frequent shifts in fan speed when the temperature fluctuates slightly around a certain threshold. This often results in unnecessary noise and wear on the fans.
Why hysteresis matters:
Hysteresis adds a temperature buffer between when the fan ramps up and when it ramps down. For example, if the ramp-up temperature is 70°C and the ramp-down is set at 65°C, the fans won’t constantly turn on and off around that range. This is a small but powerful feature that improves stability, reduces noise, and extends hardware lifespan.
Possible implementation:
Add an optional hysteresis value (in °C) that can be adjusted per fan curve.
Allow users to toggle it on/off per profile.
Show the effective fan curve including hysteresis in the UI for better clarity.
This feature is commonly available in other fan control software and BIOS configurations, and I believe many users would benefit from having it directly in CAM.
Thanks for considering this request, and keep up the great work!
Best regards,
