The fans are not spinning properly.
The fans are not spinning properly.
I began a game that required shader optimization, which increased CPU usage and fan speeds. Once completed, temperatures returned to normal, but fans remained at high RPM. Even after changing the fan curve to quiet mode in ICUE, fan speed didn’t decrease by even a fraction. After restarting the PC, everything seemed back to normal. Someone might have noticed something unusual about the cooling system or software settings.
Software issues with Icue are common; consider using MSI Afterburner instead. Avoid Nvidia overlay as it tends to cause problems—sometimes fans stop completely during heavy use. For case fans, stick to BIOS settings which usually work reliably, though I’ve seen it fail twice on Nvidia overlay (though only once in the last few years). I haven’t used Icue for fancurves, but there are plenty of reports against it, especially on my Corsair PSU where it performs perfectly.
It probably didn’t work for me because the PSU and ICUE share a special USB connection (or line), while case fans can vary widely even within the same brand. I think the ICUE is generally weak, possibly due to its limited resources, though it might depend on what’s actually connected. In short, stick to BIOS settings whenever you can.
I rely on the motherboard connectors and FanControl settings. The benefit is that if something fails, you can power it down and the BIOS will restart (maybe?). It’s handy since GPU fan curves tend to be cautious about noise rather than exact temperatures. Plus, you can link a case fan to the GPU temperature.
