arrow_downward_altDownload FreeA fan curve maps your fan speed to temperature, so your PC stays quiet when it's idle and ramps up only when it's actually working. SignalRGB ships with built-in fan curves that cover the basics for free, tuned for quiet, balanced, or full-speed cooling.
Holds fans low through everyday use for near-silent desktop work and browsing.
Eases fans up as temps climb, keeping noise and cooling in step for gaming and daily use.
Ramps fans early to prioritize low temps under heavy loads and long render sessions.
Most PC fan controller software makes you compromise: it only reaches one part of your system, locks you to a single brand, or hides real control behind a dated, clunky interface. SignalRGB doesn't.
Most setups need a different app for lighting, another for fans, another for monitoring. SignalRGB does it all in one free app, so there's no second icon in your tray.
