If you're looking to link both fans without using an LNA, you'll need to understand the wiring on each fan. Each fan has four color-coded wires, and you're planning to connect one to the CPU and another to either CPU_OPT or Case_FAN. The fans have four wires beneath their connectors, which suggests careful handling is necessary to avoid incorrect connections. You mentioned seeing a 4-pin connector on the motherboard, possibly similar to the MoBo model, but with a slight notch near three pins. The Asus Formula VIII supports this setup. Since the fans operate at around 800 RPM, which is low, you might not be concerned about noise. You could consider connecting the fans directly to the motherboard for simplicity.
Really, there are too many cables causing confusion. As they say, "If it works, why waste time?" After reinstalling, the CPU in The Medium game reaches 63 C, while other games cap at 54 C.
