Hello,
I have built a new desktop PC using the Z390 Phantom ITX and NZXT H200 (other components in my signature). The board came with BIOS v1.10 and the case with two identical 3-pin fans (1400rpm max). On the CPU Fan header i have the stock CPU fan connected. On the CPU OPT fan header i have one NZXT chassis fan connected. On the CHA FAN 1 fan header i have the other NZXT chassis fan connected. Right from the start (no Windows installed) i am facing the following issue: CPU and CPU OPT fans work as set in the BIOS (either presets or custom curves). Fan test works as intended on theese two (~500rpm up to ~3000rpm on the CPU and ~1400rpm on the 1st NZXT). However the NZXT connected to CHA FAN header goes full speed at all times. Fan test yelds same result across the % (0%...100% => 1400rpm). What i already tried: Switched fans with each other....same result. Updated BIOS to a version wich i see now that has been removed from the board support page (??) - i think v1.29 (should i be worried?)...same result. Reset CMOS on all BIOS versions...same result. Installed Windows 10 X64 Pro and ran Phantom Tuning, trying same stuff in Windows...same result. Should i RMA the board? I don't want to spend money on 4-pin PWM fan just to find out that it still doesn't work. Thank you!

SOLVED
Bought a Noctua 140mm Redux with PWM. This one can be controlled via PWM. Turns out, as ASRock support quickly replied to my support ticket, that this board cannot DC control a fan on the chassis header, by design. My last desktop board was the Asus Maximus Impact, so i guess i was spoiled. Cheers |
