Default Two HD140 as Intake's on a 4-pin Y-splitter

As the thread title suggests:

How careful should I be running two HD140's as intakes on a Y-splitter?

The motherboard doesn't advise what kind of voltage/power/etc (not an electrician, sorry!) is on a 4-pin fan header.

The HD140's are operating voltage is between 7v and 13.2v

Can I successfully make this work with a Y-splitter?

If not, there are available fan headers to use, but trying to minimize wiring and attempt a rather nice looking cable managed case.

Appreciate any feedback.

Arrow I would use 2 fan headers

The Gigabyte X299 Gaming 9 has 6 fan headers (SYS_FAN1/2/3/4/5 + HPWR_FAN) so I would connect each fan to it's own header.

As both the HD140 fans and headers are 4-pin PWM you should set PWM mode in the BIOS and the voltage will then be a constant +12 volts.

Thanks for the heads up, I note PWM Phase Control has a bunch of settings, such as
eXm Perf (Extreme Performance),
High Perf (High Performance),
Perf (Performance),
Balanced,
Mid PWR (Mid Power); and
Lite PWR (Light Power)

There is "Smart Fan 5" in the BIOS too, so I'll check that out as well.

Thanks mate, appreciate it.
