After Windows (10 x64) Update installed BIOS 327 on my laptop G17 G713QR , fans in Manual mode now have lowest speed of 3000rpm on both CPU and GPU. My 24/7 fan profile uses 1900/1600rpm as lowest speeds. I set 54W max for CPU and stock GPU for this profile.
Latest Armoury Crate ofcourse and I think I had BIOS 325 before this 327, things worked well then.
This is similar problem when Armoury Crate was updated quite some time ago(more than 6 monts ago?): Manual mode behaved exactly like Turbo mode, fans would decrease to minimum 3000rpm and then stop completely, 0 rpm at 45C and lower.
I only use Manual mode
I'm back on BIOS 325... fan profiles work again in Manual mode.
