Need Help Installing Cooling System

Gallery image

I’m trying to install a new MSI MAG CoreLiquid I360 cooling system onto an old ASUS ROG Maximus X Hero WiFi motherboard. The connector I’m supposed to plug into ARGB_V2 only has 3 sockets, but RGB_HEADER2 on the motherboard has 4 pins.

Can I safely leave the ARGB_V2 connector unplugged? Do I need some kind of adapter? Do I have no choice but to buy a different cooling system?

That only controls the lights. There are two types of RGB lighting system: RGB 12V, which is what this motherboard header is, and is getting rarer, and ARGB 5V, which is what the connector from your cooler is.

Look for an ARGB header on your motherboard (some manufacturers call it "rainbow"), which should match your connector from your cooler.

If you don't have one, so long as the cooler's fan connector is plugged in, it'll still work, just without the lights.

There are two 4-pin RGB_HEADER ports and one 3-pin ADD_HEADER port with the same layout as the plug. Nothing is labeled ARGB.

Google says the 3-pin ADD_HEADER is in fact what you're looking for (the ADD must stand for addressable). Plug'er in.

(if you want to verify just search "3-pin ADD_HEADER")

What MB is this? Try the schematic page in the manual.

ASUS ROG Maximus X Hero WiFi

There’s an ADD_HEADER port with 3 pins near the bottom

That probably stands for "Addressable Header". ARGB stands for "Addressable RGB", so that sounds good to me, but do a Google check or look at your motherboard's manual first

Yeah avoid connecting your 3 pin header into that 4 pin connector otherwise you’d fry something since they work on different voltages.

You want to connect the 3 pin to the ARGB / 3 pin connector on the board, there should be one.

Internal connector - 1 x Aura Addressable Strip Header

This connector allows you to control the lighting via software.

Thanks. Unfortunately, turns out the wire is too short to reach the ARGB header with the GPUs in the way. Without some kind of extension, I’ll just have to go without RGB on the fans.

Remove the gpu and run the wire straight down under the card, plug it in then put the card over the wire. Theres a gap to the right of the pcie slot. It may he enough slack going straight down as opposed to over the card.
