acsrand Posted September 22, 2019 Share Posted September 22, 2019 This is a 1st time bld. for me (very newbee). Sys: gigabyte z390 Aorus Pro WiFi MOBO, i9-9900K CPU: Not sure which of the MOBO Fan header to connect the H150i single pin "pump tach" (I believe the only function of this single pin connection is for the MOBO to read the pump tach., is that correct?) Options for this MOBO are: CPU_FAN/SYS_FAN1, or SYS_FAN2/SYS_FAN3/SYS_Fan4 (Fan Headers) or SYS_FAN5/6_PUMP (System Fan/Water Cooling Pump Headers) or CPU_OPT (Water Cooling CPU Fan Header) I need to assign one of the headers to my case fans, but beyond that the headers are not assigned as yet. Also, the H150i USB 2.0 conn.: Will the iCUE ver. 3.18.77 recognize this USB connection or do I need to do something so iCUE recognizes the H150i USB connection? One concern is that until I get everything setup:, BIOS, iCUE, etc. I want to make sure the CPU does not go into an overheat situation. Link to comment Share on other sites More sharing options...
Furyan Posted September 23, 2019 Share Posted September 23, 2019 I connected my H150i to the CPU FAN header (3 pin), no issues. Not sure if that version will see the H150i. If not, just have iCUE do an update to the latest version (came out a couple days ago, 3.20.80). Link to comment Share on other sites More sharing options...
acsrand Posted September 23, 2019 Author Share Posted September 23, 2019 Furyan, the Corsair tech. told me not to upgrade the iCUE from 3.18.77 because it can cause issues so I was not planning to upgrade iCUE. Link to comment Share on other sites More sharing options...
c-attack Posted September 23, 2019 Share Posted September 23, 2019 It doesn't really matter which MB header you use for the "dummy header" on the H150i. If you have nothing on CPU Fan, you will have to disable the BIOS warning system in order to boot. Putting the H150i pump there solves that problem as well as makes the warning useful should the pump not start at power on. However, the MB connection is not required for the pump to work. The USB 2 connection is how the software and device communicate and power is SATA. iCUE 3.19 was the problematic one for some users with specific hardware, although it does not sounds like you have Corsair RGB RAM and that version has already been replaced with the 3.20 mentioned above. Moot point either way. Link to comment Share on other sites More sharing options...
