[SOLVED] Can I test fans (and RGB capability) without a fully-functioning PC?

[MoreMoneyThanSense]

Basically I want to test a bunch of fans before pulling the trigger on any of them in particular.

I have my PSU and mobo, but my CPU (3950x) isn't out yet.

I want to test the fans for their noise levels, how they look with RGB, etc. So I was planning to get a whole bunch (Noctua a12x25, Corsair ML 120 Pro RGB, Corsair ML 120 Pro, Corsair LL 120 RGB, Noiseblocker NB-eLoop Series B12-PS, Noctua NF-P12 redux-1700 PWM, Noctua NF-F12 PWM chromax.Black.swap, etc) plus a Phantek Halo Lux to mix and match.

But not sure how I'd really go about testing everything without a fully functioning PC/motherboard/etc.

What are my options?

Do you have a separate power supply? If so, you can jump the 24-pin ATX plug and it will power components allowing you to test.

I have a PSU (Seasonic Prime Ultra Titanium 1000W) though not hooked up to anything at the moment.

It is pretty simple, you can either use an ATX PSU jumping connector (a few dollars from Amazon) or by using a piece of wire to jump green to any black:

I do have a Rigol power supply unit in case I can use that instead (though I still need to learn how to use it somewhat).

Anyway: Even with the PSU, I cannot test RGB (or the Halo) this way though correct? Just the fan speed / noise?
