Question about ROG-Strix-X570-F chipset fan; does not seem to be spinning.

[Stokstaartje420]

Hey fellow techies! 

 

Yesterday I've finished my sick new build. Everything works fine, only I have noticed that the chipset-fan of my ASUS ROG-Strix-X570-F mainboard does not seem to be spinning! I've also noticed that there is a "M2_fan connector" on my mainboard (See In the manual, page 31). I have no connections to this connector, because I just assumed that a fan directly on the mainboard wouldn't need to be connected.

 

Do I need to connect something to get the mainboard chipset fan to spin? And why is there a M2_fan connector on the mainboard anyways? Given the layout of the mainboard, I would not know where to place an extra fan to cool the M2 SSD's, because they are under a heatsink anyways. 

 

Kindest regards, Yme

What temps is it at? Many boards won't run the fan if the temps aren't that high.

The chipset fan only spins up when it gets hot, so most of the times it wont spin. Not sure about the m2 fan connector, but its probably just a fan connector regulated by the temperature of the m2 drive, for active cooling heatsinks or something

The chipset fans on pretty much every X570 with one default to zero RPM until it reaches some threshold temp.

It's for stuff like this: https://www.xpg.com/en/feature/494/

Thanks for all the replies guys! It's all clear to me now.

I have not checked the temp yet. I just noticed that my fan wasn't spinning. I will check tonight and let you know. I do have an m2 SSD installed, and I have a rather big GPU so that it overlaps the chipset fan a little bit. How important is this chipset fan anyways, If it doesn't seem to be spinning that much?

And the treshold temp being the temp of the mainboard? Can I see this somewhere in the bios?

It'll probably be where fan control is. However, I don't think you can actually create a custom curve/profile and have to use the defaults provided, but there's usually like 3 - normal, silent and aggressive.

 

It's this way for pretty much every X570 afaik.
