2 fans in 1 header?

I'm ordering the Noctua NA-SYC1 Black 11cm 4Pin PWM Fan Power Splitter Cables (2 Pack) and I'm wondering if it's safe to plug my Corsair Air Series AF120 LED Quiet Edition and my Cryorig QF120 Performance together to the splitter then onto a single fan header.

Add their current ratings up. If it's on or below 1A then it's fine. Otherwise you would want to use the header for AIO liquid pump instead (if the board even has one)

It's printed on the sticker behind the fans where the motor is.

You can find it here

You can split more than 2 fans as long as the total current is not more than 1A.

My system specs:

You mean a single fan header on the mobo right? I did it last year on an fx build and i had an asus mobo of quite good quality (by did it last year i meant that i connected multiple fans to a header) , due to this eventually fans ended up going haywire and some fans ended not working anymore on those headers, my advice: better to just get a separated controller for the fans.

If you're pulling more than 1A from a single fan header, yes, it's going to screw up over time. If you're pulling less than 1A, it should work fine indefinitely. I would recommend something like a SATA-powered PWM fan hub before going to a separate fan controller in most cases, especially as 5.25" and 3.5" bays disappear.

I enjoy buying junk and sinking more money than it's worth into it to make it less junk.

I would say it's fine. There aren't many fans that pull over 0.5A. Controlling wise there's things to remember. Since they are different fans, they will differ in speed.

Can you confirm with me? On the cryorig fan it just say dc 12v

Two will be fine, three sometimes pushes past 1 amp.  You should be fine.

Cryorig hasn't made it easy, but they are 0.12A. You are fine.
