I recently bought a new PC case and cooler. In the description of the case on the website, it was written that it has a backlight controller. I assembled everything, connected it, but the backlight on my cooler does not work.

But together with the case, another cooler came from the store, which had already been connected to it in advance. And here it is perfectly synchronized with the case.

But due to the fact that these coolers have slightly different connectors, they are connected differently. The cooler that was pre-installed together with the case is connected to the connector coming from the case and is additionally connected to SATA. And the cooler that I bought separately has 2 connectors, one with 4pin, which, as I understand it, should go to the motherboard. And another connector, 3pin, which, as I understand it, is used for ARGB backlight. And the same 3pin connector also comes from the case.BUT when I plugged it all in, the light on my cooler that I installed doesn't come on at all. I measured the voltage on the 3pin connector coming from the case, and there is 5V, as it should be.

Maybe someone knows how to connect this backlight?
