A routine driver update from AMD has exposed an unexpected flaw in the way Zero RPM mode behaves on several Radeon GPUs. The feature, designed to stop fans spinning during idle periods, now fails to re-enable fan rotation when monitors wake up, leaving GPUs vulnerable to overheating.
Zero RPM is a standard function in modern graphics cards, allowing passive cooling when system load drops. Once temperatures rise above a set threshold, the GPU’s fans should kick back into action. However, users upgrading to driver version 26.5.1 WHQL report that this sequence breaks down after monitor sleep cycles. When the display reactivates, Zero RPM remains locked on, preventing fan activation even as thermal thresholds are exceeded.
Two immediate workarounds exist: a system reboot or a complete driver removal using AMD’s Driver Uninstaller or Display Driver Uninstaller (DDU). The latter erases old fan profiles, forcing a clean reinstall of the latest drivers. This means each new driver update could reset fan behavior, adding friction to an otherwise seamless process.
Despite the release of 26.5.2 WHQL yesterday, no fixes for this issue have been addressed. Whether future updates will correct it remains unclear, as the problem may not yet be widespread enough to trigger a priority patch.
The disruption underscores a growing tension between driver stability and feature refinement in AMD’s GPU ecosystem. For enterprise users relying on Zero RPM for noise reduction and longevity, this update introduces unnecessary complexity without clear resolution on the horizon.
