I have completed assembly of PC using this parts list already. Everything works fine. CPU temperature hovers around 30C. What is nagging me is that I am not sure if I fully utilize interface between Z390 AORUS Elite MOBO and NZXT Kraken X72 liquid CPU cooler. MOBO has 3 options for connecting liquid cooler:
CPU_FAN CPU_OPT (Water cooling CPU header) SYS_FAN1/2/3_PUMP (System Fan/Water Cooling Pump Headers)
All 3 options have the same pinout:
Pin1 GND Pin2 Voltage speed control Pin3 Sense Pin4 PWM speed control
NZXT told me to connect pump tach cable to connector number 1. Their connector has only 2 cables going to PIN1 and PIN3. Then obviously it does not matter where I plug it since only PIN 1 and PIN 3 are connected. My question is what is the purpose of the pin2 and 4? It seems to me that Z390 can do some additional control of liquid cooling system and I am not utilizing it. Should I purchase another liquid cooling system which is utilizing all pins on MOBO to achieve better cooling performance? And what it would be? Thank you.
