Cooler Master Masterfan MF120R installation

Recommended Posts

Posted · Original PosterOP

I have a Gigabyte Aorus Elite B450 motherboard and I have a kit of three Cooler Master Masterfans MF 120R (in a kit) with a controller, and a fourth loose one.

My end goal is to get these connected and synced with the lighting on the motherboard, and so my questions are:

The fan controller supports pass through with Gigabyte’s RGB fusion. It comes with the a three pin connector (as wide as Four pins but one with one of them blanked out)

There are two matching headers named V DG on the motherboard with jumpers enabling you to chose between 5 and 12 volts.

Question one

- can I connect the controller to the V DG header directly and expect it to sync up - and do I set it to 5V or 12 V?

Question two

- Can I connect the fourth fan directly to the second V DG header and do I set it to 5 or 12 V?

I should mention, that my wife three away the documentation by mistake, which would probably have made my life a fair bit easier.

3 pin = 5 volts

4 pin = 12 volts

You can quite easily find all the relevant documents online in pdf form.
Aorus B450 Elite
CoolerMaster MF120R aRGB 3-in-1 kit

The aRGB in your fans is 5V.

 

I wouldn't really trust into a 3pin = 5V, 4pin = 12V rule, while it is the case most of the time, some companies might decide on going their own way, for example the NZXT RGB strips are 4pin 5V. The rule is rather 3pin = addressable RGB, 4pin = simple RGB, but that doesn't define the voltage of the strips. It's always best to consult the manual on the voltage.

The 3 pin connectors on my motherboard can either be 5 or 12 v, controlled by a jumper.

 

Anyways, I just took a chance and plugged it in and it is working, so all is good.
