CoolerMaster and ASUS have introduced a new version of ARGB lighting units they call ARGB Gen2. These are different electrically from the original ARGB, and those companies (and many others also) still sell original ARGB systems. The CoolerMaster software utility MasterPlus+ is designed for use with their own ARGB Controllerers. They have a new Controller for the Gen2 version, and older models for original ARGB.
HOWEVER, the web page I found for your cooler system
https://www.coolermaster.com/my/en-...s/masterliquid-ml360l-argb-v2/#specifications
in the downloadable manual indicates that this system does NOT come with one of those ARGB Controllers. Instead it comes with a HUB for both PWM fan and ARGB lighting systems. It is NOT for use with MasterPlus+ software. The intent is that you connect your pump and rad fan cables to the appropriate ports of that Hub. Then you connect to the Hub a SATA power output from the PSU, a cable from a 4-pin input port of the Hub to the mobo CPU_FAN 4-pin fan header, and another cable from an adjacent port to the 3-pin D_LED header on your mobo - see manual p. 21, item 6. Do NOT attempt to connect to the 4-pin LED_C header next to that! NOTE that this last cable has TWO input heads - one each for use with the two slightly different 3-pin ARGB headers used on some mobos. There should be only one way to plug this cable into that mobo header. Once these connections are made, ALL control of rad fan motors and of their frame lights is done using the MOBO tools - either within BIOS Setup or using the Gigabyte RGB Fusion software. MasterPlus+ is NOT involved, and should be un-installed from your system.
Note that you normally would NOT connect any case ventilation fan MOTOR cables to the PWM fan output ports of this Hub because it is controlling all its fans according to the temperature sensor inside the CPU chip. However, you MIGHT choose to connect the LIGHTING cables from such fans to ports of this Hub so all the lights are synchronized.
