ARGB hub issue with Lancool 205 mesh—fans still work fine.
ARGB hub issue with Lancool 205 mesh—fans still work fine.
I made my initial attempt with a lian li Lancool 205 mesh case featuring an ARGB fan hub. The case originally came with three fans, but I used a Mag Coreliquid 280R cooler that had two fans. All fans connected to the hub, and I experimented with different ARGB headers and even other fan connections. The chip’s LED lights function properly, yet none of the fan indicators illuminate. The motherboard software manages both the cooler lighting and fan speeds accurately. However, the fan lights remain off—though they spin freely and are controlled by the board for speed adjustments. I’ve changed the ARGB header, tried cycling through color modes and switches, updated the MSI LED Firmware, and rearranged fan connections on the hub. I’ve attached photos of the chip lighting successfully but not the fans. Currently, the hub is daisy-chained to the cooler light without success. Could you help identify what went wrong? This is my first build for this project, and I’m still confused about the lights! Thanks for your assistance.
I'm facing the same problem again. I'm wondering if you managed to fix it. What was the solution?
It varies. I recommended connecting to the motherboard but didn’t get a response. Whether it works depends on several factors: What model of board do you have? How much current do your fans draw? Are they RGB-enabled? Do you have the right type of RGB cable for your board? A standard 4-pin connector can handle about 1 amp, while the labeled “pump” connector usually supports 4A. Of course, in real life it’s often less. My guideline is to keep no more than three case fans on a single port. Most case fans draw around 0.2A, so that’s about 0.6A total. I’ve heard some people manage a .5 limit and only get two fans on one header for 0.4A. Alternatively, you could use five fans with a standard header and twenty with a pump header—just be careful not to overload the board. The original poster had an MSI all-in-one with RGB, which suggests they used a jrainbow setup.
Just using argb might not be enough. Apparently, when manufacturers pushed rgb standards, they quickly abandoned any real commitment. Each tried to make their own rules, hoping others would pay them to adopt it. Of course, no one did—everyone had their own version, and none actually built the lights themselves. Companies like Sylvania agreed on a standard long before computer fans caught on, so each “unique” design mostly just meant not being compatible with the real thing. The whole situation felt as foolish and self-serving as the Asshat from dragonsden’s actions toward the cat genie. Not sure what happened with argb. It seems it only works for that specific motherboard model. Edited May 11, 2023 by Bombastinator
Sure, I can help with that. The system functions properly, yet the fans aren't visible in the interface.
Bios typically includes a fan control curve feature. You often have to select the sensor it adjusts from, but sometimes that’s not possible. Modern MSI models allow this adjustment. Earlier ASUS models (2015) didn’t support it. Usually only motherboard and CPU sensors were available; GPU sensors weren’t pull-downable.
