[SOLVED] 6pin rgb fan to 4 pin mobo

[Josee29]

Hi everyone,

Im wondering if i can somehow connect the 6 pin fan to my 4 pin mobo, my pc case doesnt come with a fan controller. Is there any way i can connect it to my mobo?

What fan is it?
If I remember correctly, the 6 pin rgb connector is just for rgb and is an entirely seperate thing from fan connetors and wouldn't even come close to connecting.
You would probably be better off buying a cheap rgb controller. You can get some for like.. 30$ I think.
(Don't get from corsair! they have a proprietery connector.)

"6-pin fan" screams NON-standard connector.The standard way for all current RGB or ARGB fans is that each afan has TWO cables - separate ones for the fan MOTOR and the frame LIGHTS. With NO info on which hole is which on your s-pin female fan cable connector, you have NO way to know how to rig that with custom wiring to any standard mobo header. Does the maker of your fans also sell their own Controller box for these fans that uses their non-standard connection system?

yes , but i buy a new cheap pc case recently. so the seller gives me a rgb fan as freegift but both the fan and case dont come with a controller.

If you got only ONE such free fan, I advise you do NOT use it. To get a Controller or to figure out how to custom re-wire it may cost you more than it is worth. Just buy some standard fans so you can use them with your mobo.

All mobos have fan headers you can use for the motor of any standard fan. IF your mobo has the right type of lighting header you CAN (if you choose) buy fans with lights in their frames, too. These come in two standard types: plain RGB and Addressable RGB. You MUST match the fan light type to the header type your mobo has. So tell us the maker and exact model of your mobo and we can advise what fan design to buy.

there are some decent quality fans out there using a 6pin connection for both power & LED connection.

Thermaltake offers a few versions i've run into that require their own hub that then converts to standard connections for motherboard control.

i would not recommend bothering with any of them and just going with all standard 4pin PWM power control and all standard 3pin aRGB LED control.
this will make all future setups and compatibility much easier down the line.

The manual for that mobo says it has NO headers for lights. So IF you really want lights in fan frames, you will need to buy also a lighting Controller box. But the simpler and cheaper solution is to buy only fans with NO lights.

Regarding fan motors, the mobo has only two fan headers. One is for the CPU cooler system and should be used only for that - its automatic controls are based in the temperature sensor built into the CPU chip. This header can work only with the newer 4-pin PWM fan type, but those are common in CPU cooler systems. The other is the CHA_FAN header to be used for case ventilation fans. Its guide is a different temp sensor built into the mobo. It can be configured for use either with the newer 4-pin PWM fans or with older 3-pin Voltage Control fans. I'd recommend the 4-pin style. This header can be used with a SPLITTER to connect several fans to it provided you ensure you do not use too many. How many? The limit is that the header can supply power at 12 VDC up to a max total load of 1.0 A for all fans connected to it. Fans come with specs for max current draw, and usually the limit is on the fan's label. Typical current fans draw from 0.10 to 0.25 A max per fan, so you CAN connect up to 4 such fans to a single header using a SPLITTER like this example

https://www.amazon.com/Cable-Matters-2-Pack-Way-Splitter/dp/B07PXLHNZ6/ref=sr_1_3?crid=F0BTDCL9ODU1&keywords=fan+splitter&qid=1647873102&sprefix=fan+splitter,aps,89&sr=8-3

That is a 2-pack of 4-pin Splitters that look like a collection of cable "arms" - this model has 3 outputs, but other varieties exist.

https://www.amazon.com/ThreeBulls-Cooling-Splitter-Adapter-Computer/dp/B07M5P7VHG/ref=sr_1_8?crid=F0BTDCL9ODU1&keywords=fan+splitter&qid=1647873222&sprefix=fan+splitter,aps,89&sr=8-8

That one looks like a small circuit board with 5 output headers. Although one of those is labelled "CPU", do NOT plug your CPU cooler in there. Plug your CPU cooler into your mobo's CPU_FAN header. But DO plug one of your CASE fans into the Splitter header with the "CPU" label. Every Splitter is wired to send back to the mobo host header the speed signal of only ONE of its fans and ignore the speeds of the others. On this circuit board design, the one output labelled "CPU" is the only one that does this.

Note that a SPLITTER has one input that plugs into a header on the mobo, and several outputs for fans. It has NO other connections, and fans draw all their power from the host header. You do not need a different device called a fan HUB which may look very similar. A HUB can be identified because it has a third type of connection - a cable that must plug into a power output (either SATA or 4-pin Molex) from the PSU. It draws all power for the fans from the PSU so it is not limited by the host header's 1.0 A limit. It works only with 4-pin fans, which is OK for you if that is what you buy. But you really only need a Hub if you are installing many fans. Watch for these details when buying because too many seller misuse and confuse the terms "Splitter" and Hub".

IF you decide you want fans with lights, you will need a lighting Controller as I said. If you go that route, many sellers will sell kits of a few lighted fans plus a Controller and some means of using the controls. If you need more details on that option, post back here.
