Where to buy 4048 1u fans?

[HorizonXP]

I bought a Chenbro RM13704 from @Russ and it uses 4048 fans. 4 of them are 4-wire PWM fans, and 1 of them is a 3-wire fan. The X9DRD-iF reduces the speed on the 4-wire fans to ~2.5k RPM, but it looks like it runs the 3-wire fan at 12k RPM (if the sensor readings are to be believed).

So I'm looking to replace the 3-wire fan with a 4-wire one. Also, there's space for a 6th fan, so I'm thinking of adding another 4-wire fan too.

But I can't find these fans anywhere online! If someone can point me to where I can buy them, I would really appreciate it. Thanks!

Maybe either of these would fit? They are 40mm x 40mm x 48mm deep, 12VDC and PWM controlled. Looks like bare leads, but crimping fan connector leads is fairly easy.

That's a good idea, but now I need to find fan connector leads and a crimp tool, lol

Another option is to buy some PWM fan extensions and then just solder the wires together. It would be cheaper, plus it would afford you extra length if you needed it.
