What is an EXT_FAN header?

[bb2013]

I was having a quick read in my motherboard installation manual (Asus H170 Pro Gaming) and came across this. The mobo supports upto 3 chassis fans but I'm unsure what the EXT_FAN header is for. If I was to guess is it for something like a NZXT grid???

Does anyone know???

Thanks

Apparently it's a device that never came to be.

I have a NZXT grid, would I connect it to the EXT_FAN header?

No. The EXT_fan on that board is a 5 pin made only for that card that apparently isn't made.

The ext fan header is for attaching another fan that will be controlled the same as the fan header is that that ext. is an extension of. The ext means extension.

Page 1-19. It's a 5 pin connector that doesn't fit with any 3 or 4 pin fan header, for an external "fan extension card", as I've said for the 3rd time. Please don't spread misinformation if you can't back it up.

Ton's of pics of the card.

It was only sold with the X99-Pro boards from Asus and you can't buy the card separately except for apparently EBay, where owners of X99-Pro's that never used them are selling them now and again.
