fans blast at full speed on boot can't figure it out

I've got a 2021 G14 (Ryzen 9 5900HS + RTX 3060), clean Windows 11 install, using G-Helper instead of Armoury Crate. When I turn the laptop on, the fans are normal during BIOS/boot, but a few seconds after I reach the Windows desktop they suddenly ramp to 100% and stay there — even though the CPU isn't even hitting 50°C. Setting Silent mode in G-Helper does nothing, the fans just ignore it.

The weird part is I had this exact issue about 2 years ago and fixed it with some software tweak, but I honestly can't remember what I did. Now it's back, and this time it happens on almost every boot. A full shutdown used to fix it, but lately even that doesn't always work. I'm pretty sure it started after a Windows update before it was everything fine then suddenly this started happing everyday again after 2 years

I've tried basically everything: disabled Modern Standby, rolled back the ASUS System Control Interface driver to an older version, ran G-Helper with SYSTEM privileges (psexec), did an EC reset, uninstalled the update and went back to 24H2. I also ran the MyASUS hardware fan test and it passed, so it doesn't a hardware issue. I'm on BIOS 415

Has anyone actually fixed this permanently, or remembers the software fix from a couple years back?
