Windows 11 installation issue on case fan failure
Windows 11 installation issue on case fan failure
I have four fans—three intakes and one exhaust—linked via a single controller. After powering on the PC, all fans spin initially, but after startup the exhaust stops working. Only the intake fans run when I launch the desktop. In BIOS settings everything resumes. Recently, I switched to Windows 11, wondering if that might affect it, though it seems unrelated. The fan I’m talking about is different from the others—it’s an older model and from another brand.
Your exhaust fan needs a bit more voltage or PWM strength to keep operating compared to other fans. Modify the fan curve to raise the lowest speed setting. The CPU usually runs slightly hotter in BIOS than when idle on the desktop since power-saving options like throttling are turned off. Once you reach your desktop, the CPU cools down a bit, making the fan curve fall below the required speed for your exhaust fan.
This program is completely free and offers numerous excellent guides from the developer on YouTube, making it easier to design and manage your fan curves with precision. You won’t need to visit BIOS settings to verify anything—this approach is secure and has been highlighted on JayTwocents and other platforms! https://github.com/Rem0o/FanControl.Releases
