Hello,

I have a new PC since last winter and with the Lian Li LANCOOL II Mesh C Performance case I have this problem:
When I change fan speed from Auto to Full with cases own switch it goes to Full but when switching back to Auto it stays on Full as long as I dont shut down the PC.
I have not touched the cases own fan controller on the backtray of motherboard.
Is this a fault or is this behaviour the same for others ?

I think I have to resort to manufacturer email about this problem.

Support from Lian Li did say I should put fan header into PWM mode in Bios. That solved the issue. Now I can change fan speed switch to any position and it always reacts.
