Wardrobe ventilation with Noctua fans.

I'd like to use two 92mm Noctua fans to provide airflow to the top and bottom of a built in wardrobe.

I have a socket so I thought I could use the Noctua NV-PS1 for mains to 12v, and then the Noctua NA-FC1 as a fan controller to control the speed of both fans.

This issue I have is the fans are going to be situated about 2.5 meters away from each other and I can't find any 4 pin fan cables that length because it's quite a niche use case; obviously daisy chaining loads of fan cables adds lots of failure points.

Anyone got any ideas as to how I connect both fans to the NA-FC1 quite far away from each other?
 
I use one fan like that to ventilate a cabinet with some electronics in it.
I just used two wires, and a switchable PSU I bought for a tenner off Amazon. Pins one and two are the supply. Ignore everything else. 6V runs the fan very quiet but you usually have 7.5V, 9V and 12V as options if needed.
 
What power source are you using for your grow lamps? :D

Just make your own cables up. Its low voltage cabling, you cant go far wrong, even if you butcher your current 4 pins and extend them.

Ha, I posted this on an electrical subreddit and got a very similar response, I wish I was that interesting, but alas, no. It's genuinely to try and get more airflow for my built in wardrobe.

Can you link me the type of thing you mean?

This is the type I use. I am pretty sure they do one that is even less power. You only need a few watts.

Amazon Power Adapter

You want the screw terminal connector to extend the wires to the fan.

USB would probably run the fan very well. I run mine at 6V but I just threw an Antec 12V PWM 120mm fan on a variable power supply and tested it at 5V and it worked just fine. It was drawing 0.07A so only consuming 0.35W.
