Just got my a200 yesterday. Windows 11 pre-installed out of the box. Ordered directly from Corsair.
I'm getting the same overheating critical errors.
In iCUE, the "default" fan profile fixes the % to ZERO (!!!).
"Extreme" fixes it to 100%.
Updated iCUE to 4.23.137. Same issue.
The fan profiles don't offer a way to set a custom curve, despite what the online documentation and videos advertise. I can only set a "fixed" percent.
I'll try to Corsair support pathway, but considering that it's 8-months now since the first report I'm not gonna hold my breath...
