garyonn92 Posted January 14, 2020 Share Posted January 14, 2020 (edited) Hi all, I'm using a h100i pro aio to cool my 8700k on a msi z390 ace mobo. Currently I'm using the 2 fans comes with the aio connected to the PUMP_FAN1 header on the mobo, and wanted to add another 2 ML120 fans for a push/pull configuration. Should I use 2 PWM splitter (1 to 2) to connect the 4 fans before connecting aio fan connector? Or just 1 PWM splitter to connect the 2 new fans and plug into CPU_FAN1 header? Attached some paint job draw to better illustrate what I'm planning to do https://imgur.com/a/7nWPczy Edited January 14, 2020 by garyonn92 Link to comment Share on other sites More sharing options...
DevBiker Posted January 14, 2020 Share Posted January 14, 2020 You'll be able to power those fans from the pump header just fine. I would add 2 splitters - 1 on each of the pump headers. This will allow you to control them together based on coolant temp, which the CPU_FAN header won't allow you to do. Link to comment Share on other sites More sharing options...
