AMD GPU owners take to Reddit to report fan problem with driver update — Zero RPM feature could cause GPU temperatures to rise unexpectedly

AMD’s Adrenalin 26.5.1 graphics driver, released on May 6, has raised concerns among AMD graphics card owners because it appears to break the Zero RPM function on some of its best graphics cards. The function seems to stop working after a monitor resumes from sleep or when turned on again, causing the graphics card’s temperatures to rise silently.

For those unfamiliar with Zero RPM, it is a function that automatically turns off the cooling fans when the graphics card is idle or under a light workload, such as tasks like web browsing or watching videos. The primary benefits of the Zero RPM feature include reducing system noise and dust accumulation inside the graphics card over time, while also prolonging the lifespan of the cooling fans by minimizing unnecessary use.

Redditor Evelyne-Tourneciel observed that Zero RPM activates as usual when the monitor goes to sleep or when is turned off. However, upon resuming from sleep or after powering the monitor back on, Zero RPM remains activated, so the graphics card’s cooling fans stay off. The issue poses a significant risk, as you may unknowingly begin gaming or other demanding tasks while the cooling fans remain idle, preventing proper heat dissipation.

Since the fans fail to spin, the graphics card’s temperatures will rise quickly, potentially leading to thermal throttling, reduced performance, or even hardware damage. It’s especially concerning for AMD graphics card owners in regions with harsh climates, since the risk of overheating is higher.

In addition to Evelyne-Tourneciel, at least four other AMD graphics card owners have reported experiencing the same Zero RPM malfunction with the Adrenalin 26.5.1 graphics driver.

The first and most straightforward stopgap workaround is to restart your system. It is far from ideal, though, as it requires you to reboot your computer every time the monitor resumes from sleep or is powered back on. The process can quickly become tedious and annoying if you frequently step away from your computer. You could disable Zero RPM altogether, but that means missing out on its benefits.

A more technical fix that has proven effective for some users is to perform a clean offline installation of the AMD graphics drivers using a third-party utility like Display Driver Uninstaller (DDU). DDU can help completely remove all traces of the current and previous Adrenaline drivers before reinstalling a fresh copy of the driver that you want.

For a more hassle-free solution, you can roll back the Adrenalin driver to an earlier version, such as Adrenalin 26.3.1, with DDU, since that version does not appear to have the Zero RPM bug. That means missing out on new features, optimizations, or security updates introduced in the latest releases, though.

Evelyne-Tourneciel has seemingly reported the issue to AMD. However, it seems that AMD hasn’t acknowledged the bug or provided a solution. The latest Adrenalin 26.5.2 graphics driver, which just came out of the oven today, has no mentions of the Zero RPM bug. If you’re experiencing the same issue, we recommend submitting a bug report to AMD so the chipmaker can get to the bottom of it.
