Did you also make the connection to the CPU_FAN header? That is where the cooler gets its power for both the fan and the lights, AND where its fan speed is controlled, AND how the mobo can check that the fan actually is working (from the speed signal). I hope you did NOT also connect the other cable for Option (a). Then you DO need to download and use the lighting control software utility. The other end of that plugs into a mobo (10-1) pin USB2 header. You use the other cable with THREE holes in one end, and plug it into the OTHER (3-pin) socket on the cooler side. (b) INSTEAD of that, if you choose, or if you have no 4-pin plain RGB mobo header (this appears to be your case, OP) you do not use that cable.

If you use this method you do not need the special software for the Wraith Prism. If you have such a header, this way you can synchronize the Prism's display with your other plain RGB lights. item 1 AMD WRAITH PRISM RGB CPU Cooler - AM4 - USEDAMD WRAITH PRISM RGB CPU Cooler - AM4 - USED £10.000 bids2d 5h + £5.00 postage item 2 AMD Ryzen 7 3700X AM4 Wraith Prism CPU Cooler RGB LED (Cooler Only)AMD Ryzen 7 3700X AM4 Wraith Prism CPU Cooler RGB LED (Cooler Only) £30.00 + £6. (a) connect a cable with FOUR holes into a recessed 4-pin socket on the side of the cooler, and the other end of this goes to a mobo 4-pin (12 VDC) PLAIN RGB header IF you have one. There are two connections to make with the Wraith Prism, and one NOT to make.įirst, its female 4-pin FAN connector must plug into your mobo's CPU_FAN header.
