CPU fan off of Commander?

Only if you want to control it via iCUE. Otherwise the motherboard does it just as well.

if you are happy with your cooler and it doesn't have an exotic fan retention design, you could simply replace just the fan by a ML.

For an actual air cooler, my preference would be to leave on the MB CPU FAN as long as you have some BIOS programmable options.  Unlike a water cooling system, you can't have much lag time between heat transfer and dispersal.  The MB will make sure it is always moving, regardless of the software environment.  Also none of the Corsair controllers will have any kind of hysteresis when on CPU temp.  It may be a roller coaster ride.

I'm a fan of dedicated hardware.
It's not the worst of motherboards, it's the Asrock z370 pro4, but I am generally suspicious of motherboard quality, there are so many components they often cheap out on, have bad drivers for and whatnot....

I was expecting something like that.
Well the ML fan is going to be my main focus anyway so no biggie.

then i hope the Core XT has a better chip for powering the fans than the commander pro 😛

motherboard ICs are way sturdier than the wimpy transistor they used on that one. but with PWM fans it's never a problem. they just get 12V straight from the PSU constantly.

IC quality matters more when driving 3 pin fans, where heat becomes an issue on the controller (that's where the Copro does pop channels)

Damnit Corsair, that's not one of the items you should get from the fruit lady at the street corner in China.

Well, I might believe you about the Commander's quality, but I still don't trust motherboards. 
At least if something goes wrong with the Commander, it's not part of the motherboard and at last I get proper fan control. Asrock A-tuning is just bad...

Don't worry really, you will use PWM fans so it's totally fine. It's really only down to what software you use to control them, and on that regard, you'll have a way better time with iCUE
