insufficient four-pin fan connector options
you might consider purchasing fan splitters, but they won't let you control the RPM directly. you'll need a hub that supports RPM control for all your fans. alternatively, you can look into hubs with advanced fan control features. it's important to understand how your fans operate and whether the splitter can handle the required adjustments.
Uncertain about whether it belongs to cooling or motherboards—it's a motherboard component with four pins.
Typically, the third pin on a fan indicates RPM detection, allowing the motherboard to track spinning speed. A fan splitter connects several fans via a single header, with the third pin only appearing on one fan side of the splitter. This setup lets it monitor all fans at once using the fourth pin for coordinated control. Ideally, matching fan types work best on splitters. The reason is that motherboards manage fans in percentage; full speed on one type produces much higher RPM, noise, or airflow than another. PWM control requires four pins, offering more precise management than the DC control found in three-pin fans. So, for better accuracy, opt for four-pin fans and use a simple splitter to link multiple fans together.
You can use a 4-pin to 4-pin splitter without issues. There are many good options available. For controlling your fans, you should check the AMD drivers for your system—those usually handle fan settings automatically.
Building on what @minibois mentioned earlier, he addressed it as well. It’s covered, but I’m just elaborating further. For instance, you might use two top case fans with a splitter, adjusting it to a 20% rising PWM curve—this helps push more hot air out when the case gets warm. Front case fans would run at 50% with a minimum curve that increases with CPU temperature on one splitter. It’s similar, but on my server setup everything connects through a hub, regardless of fan type, and the curve still rises with case temperature. The variation comes from mixing fan types and their different RPMs.
Almost any splitter works, you can find 2/3/4 connection types, they don't need to be limited to just two. You manage them through the UE|FI/BIOS and adjust the fan curve. If you prefer manual control, a fan controller would be better.
In the bios, you can set the fans to stay below 1000-1200 RPM. If they exceed that range, they adjust their speed accordingly.
Done by fans rather than RPM... you can adjust the maximum they reach, like setting it to 80% if needed.
