Connecting LED Fans to Power Supply

[Twitty390]

Hey guys, I recently moved my Alienware X51 components to a Cooler Master Masterbox Pro 5 RGB case with a few upgrades. I was on a limited budget so I wasn’t able to upgrade the Micro ATX motherboard supplied with the Alienware. After installing everything into the case I was trying to connect my fans. I successfully got them connected to power source so they spin. But I can’t figure out what this 4-pin led connector goes to. I believed you can plug it into somewhere on the motherboard but in my case I don’t have a plugin do to my limited motherboard. Is there any way I can connect the LEDs straight to my PSU or any other option I can take? Thanks guys

I'm not quite sure how LED fans work but if it's like any other LED, you can get a regular LED controller and power it from your PSU with a molex to 12v adaptor.

 

I recently did the same thing except with an LED strip. Here are the parts you could use assuming that the connector is standard (even if it isn't, it looks like you could easily modify it to be):

molex to 12v so that you can plug it into your psu - https://www.amazon.com/gp/product/B01F5KL9T0/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

controller (should be the one you need, though if you could tell me the model of fan, it would be helpful to make sure; you could also get a cheaper option) - https://www.amazon.com/SUPERNIGHT-Remote-Controller-Light-Strip/dp/B00AF5YOK2/ref=sr_1_3?ie=UTF8&qid=1523247205&sr=8-3&keywords=led+controller&dpID=513X5GHkpwL&preST=_SY300_QL70_&dpSrc=srch

Ur mobo doesn't have the RGB header so you'll need to buy one of those rgb controllers. That's what I did cooker master sells one for $40 but I just bought a cheap one from eBay and it worked fine u will also need one of these with the rgb controller

That looks like it's proprietary.

No that's the standard plug for rgb stuff

unless it's something weird, it looks like a normal connector: 12v, G, R, B (or other order which can easily be reorderred to match an off the shelf controller

The header has the pins protruding out, and the plug has the pins protruding out, and is not a socket

Mate the plug pins are deattachable from the cable...

eww that's so expensive. with a little effort and time, you can get a much cheaper and just as effective, albeit not as simple and elegant, solution.
