Check the A520M-A-PRO guide. It doesn’t list the fan count on the site, and I couldn’t locate it on the motherboard. Please help me with the PDF.

The product features two CPU fan headers and one system fan header, essentially a fan hub.

MSI offers two fan headers on this board. Budget motherboards typically provide minimal fan options. These headers allow connecting two fans through a single port.

It will appear in the mobile manual on the product support page.

I purchased a custom-built PC with three system fans, and the CPU fan is also running. It seems the three fans are being detected as separate units despite only having two fan headers. You can connect them to other slots, but they’re still recognized individually. If you’d like, I can share a photo for clarity.

A device that can work around other fans' data or there might be more fan headers than listed in the MSI manual—maybe.

Check the wiring and observe their connections. However, the site mentions there are two fan headers available.

it seems the CPU fan header controls the CPU fan and then directs power to the two front fans, while the rear fan has its own header. Yes, they implemented a splitter.

You have two options:
1) Ensure the fans operate at low power so they won’t overload the 1A cap on a header. For example, if each fan draws around 0.2A, three fans should work on a single power supply and you can use a 3-way splitter.
2) Purchase a Powered PWM fan hub and attach it to the back of the motherboard tray, eliminating concerns about fan power consumption.

I own the same board. The problem is my case includes a 3-pin exhaust fan, but there’s no setting in the BIOS to switch from PWM to DC control. As a result, the fan runs at full power continuously.
