Yes, the fans of the product are connected with 4 pin PWM and 5V 3 pin ARGB. If your Asus Prime B550M-K motherboard has these connections, you can control the colors via the ASUS Armoury Crate / Aura Sync application without using a controller; you can control the fan speed via BIOS or Fan Xpert. ⚠️ "Compatibility & Important Considerations: • It states a 4-pin connection, but this refers to 'ARGB female + male – 4 pin'. Generally, this can be either a 3-pin (5V) or 4-pin (12V) for ARGB lighting." The product says “Fan voltage DC 12V / LED voltage DC 5V”.  • Fan power (12V) and LED power (5V) are separate, it is important that your motherboard or case controller has ARGB support.

Hello, yes sir, it will work. When you connect the Power and Return (SYS_FAN) Fans to the SYS_FAN input on the motherboard with a splitter, all fans draw their energy through the motherboard. • Attention: A single fan socket on the motherboard usually supplies 1A (12W) of power. • Rampage 7C-120S fans draw around 0.15A - 0.25A current. • Safe Limit: I recommend installing a maximum of 3 or 4 fans with a multiplier on a single input. Anything more might strain that input on the motherboard.

Air Pressure (Static Pressure): ~1.1 mmH₂O (max) • Maximum noise level: 21.2 dB(A) • Thanks to its 120 mm standard size, it fits many case models. Size: 120 x 120 x 25mm

The Rampage 7C-120S fan can blow air either inwards (air intake) or outwards (air exhaust), depending on how it's mounted in the case. But out of the box it blows out the side with the airtag (logo). So: • The open part of the fan blades (side without label) → sucks in air (air inlet) • The side with label and direction arrow on bezel → blows air (air outlet) � � If installed in front of the safe, it is usually installed to blow air inside. � � If attached to the back or top of the case, it is mounted to vent air out.
