So the motherboard is an ASUS X570 Crosshair Extreme VIII, but a number of ASUS motherboards have the WB_SENSOR socket (i think the Dark Hero too). According to the manual, which has very little information, there are probably three analog temp. sensors (“O4_TS_WB_O”, “O4_TS_WB_I”, “O4_SEN_WATER_BL”) and two boolean sensors i.e. true/false (“WATER_DETECT_IN”, “WATER_DETECT_WI”).
Reading about this plug online, most people are upset that there are no off-the-shelf watercooling solution uses it. Apparently EKWB where going to add it to a monoblock for these boards, but they never did.
Ive tried a JST SH 1mm & JST PH 2mm but as you can see from the photo neither fit. Does anyone know what it could be?
