For example Phanteks PH-TC14PE uses 3pin fans. And old, but quite popular Noctua NH-D14 - same story.
 But I still have hope that ASRock will fix it in further BIOSes. Why? Because I`v seen ASRock H370 Pro4 review where CHA_FAN1 and CHA_FAN2 have their own "Chasis Fan Control Mode" (same as CHA_FAN3):  Edited by Dmytro_o_o - 03 Aug 2018 at 6:04pm |

Thanks for the update and glad you figured it out. Odd that CHA_FAN1 does not support controlled 3 wire. As for CPU fans: have not seen a 3 wire fan on a good heat sink since before the old Intel Core 2 days.

Hi everyone.
I`v done some research with my Z370 Pro4 (BIOS v.1.50) and discovered this: CPU_FAN1: - supports PWM (4pin) fan - does not support DC (3pin) fan (only max speed on 12V) CHA_FAN1: - supports PWM (4pin) fan - does not support DC (3pin) fan (only max speed on 12V) CHA_FAN2: - supports PWM (4pin) fan - supports DC (3pin) fan CHA_FAN3/W_P: - supports PWM (4pin) fan - supports DC (3pin) fan (if you set "DC Mode" in BIOS\Advansed\HW monitor\Chasis Fan 3 Control Mode (in the end of settings list). So, I recomend PaperPlanePilot to set CHA_FAN3 in "DC Mode" Edited by Dmytro_o_o - 30 Jul 2018 at 10:24pm |

Hy,
i have a Problem with my Z370 Pro4 The Chassis FAN 1 and 3 only run at full Speed. I tried this with different types of fans with the same result. After i run the FAN Setup in the UEFI an the A Tuning Tool only CHA_FAN_2 (and CPU FAN) has a usable result. CHA_Fan_2 (an 3PIN 900RPM FAN) is OK and Looks like this: 100% 807 RPM 90% 889 RPM 80% 832 RPM 70% 754 RPM 60% 666 RPM :) 50% 571 RPM 40% 474 RPM 30% 367 RPM 20% 63 RPM 10% 0 RPM CH_FAN_1 and CH_FAN_3 (Both 3PIN 900 RPM FANS) look like this 100% 827 RPM 90% 826 RPM 80% 827 RPM 70% 829 RPM 60% 828 RPM 50% 830 RPM 40% 831 RPM 30% 833 RPM 20% 833 RPM 10% 835 RPM I also tried different UEFI Versions (actual 2.00) an reset is via CMOS Jumper, Nothing changed. Even the Fan that works on Connector 2 wont work on 1 an 3, and vice versa... Edited by PaperPlanePilot - 19 May 2018 at 6:33pm |
