Sep 23, 2020
Hi, I have some problem finding fans for my PC that support addr_led1, rgb_header1 and cha_fan2 i'm not an expert with those names and fan support so if anyone can help me i will thank them in advance
Have a look at the specs of the motherboard: Pro4-F/

  • 1 x RGB LED Header*
  • 1 x Addressable LED Header**
  • 1 x AMD Fan LED Header***
  • 1 x CPU Fan Connector (4-pin)****
  • 1 x Chassis Fan Connector (4-pin) (Smart Fan Speed Control)*
  • 1 x Chassis Fan Connector (3-pin)
*Supports in total up to 12V/3A, 36W LED Strip (dumb RGB, needs a dedicated controller)

**Supports in total up to 5V/3A, 15W LED Strip (addressable means the motherboard can control the RGB)

***The AMD Fan LED Header supports LED strips of maximum load of 3A (36W) and length up to 2.5M.

****The CPU/Chassis Fan Connector supports the CPU fan of maximum 1A (12W) fan power.
(dedicated RGB controller needed)

*CHA_FAN1 can auto detect if 3-pin (voltage regulated fan) or 4-pin fan (PWM fan) is in use. (dedicated RGB controller needed)
