WTF IS THIS FAN CONNECTOR?

Spoiler

 

Apologies if this is the wrong place to post this question I'm just wrapping up my build and have encountered a type of 4pin fan connector I've never seen before (see attached).

This is my first complete re-build in 4-5 years so I'm probably behind the times here but it's driving me mad trying to find the right adapter to get my noctua fans connected to these.

 

I've made a guess and ordered one of these https://www.amazon.co.uk/EK-Water-Blocks-Adapter-PWM-Noir/dp/B01MQOGCFV/ref=sr_1_4?keywords=pwm+adapter&qid=1640181083&sprefix=pwm+adap%2Caps%2C64&sr=8-4

But I'd love an explanation here as to what these connecters are and what I should be using here...

 

Thank you!!

Those look like standard 4-pin headers. Do the Noctua fans not just plug in?

 

Edit:

I was incorrect. See below

sadly not.. the alignment is not the same, attempted to picture it here:

The motherboard is Gigabyte z590i vision d ITX.

Isn't the notch offset on 4-pin headers?

Those are not standard headers, no.  If I'm not mistaken there should be adapters included in the accessories, no? Like what you have here?

From a quick google search it appears that the fan headers on the board are a mini version usually used on GPUs (probably since its a small ITX board). However, there should be adapters included in the box:

Yah, I guess they looked larger in the picture compared to the GPU header style

You're right, adapters in the box *facepalm* thank you!
