Cutting fan wire?

[Dark Sun]

Hi guys,

I bought some Yate fans.

My question: If I cut the 4pin connectors off will the fan still work?

cut away, just make sure its tidy as possible, you don't want the wires shorting each other

It depends - how are they wired?

If there is just a yellow wire going to the motherboard then do not cut anything. That's only for the fan speed, not power.

I've not seen a fan that's been wired for both power from the mobo and molex, so be careful what you're doing (than again, I've not had any Yates recently)

I cut the molexes off my loonies with no problems.

Careful with the chainsaw though.

The Yates I have are wired just like in the picture, it is definitely safe to cut as shown in the pic.

He wants to remove the pass-through molex connectors and just use the small 3pin connector.

Cool - not seen one like that yet

You can easily cut off either connector, 4 pin molex or 3 pin. Fans are designed to work with both (not at the same time tho!)

not true, using the diagram to explain

You can cut off B+C and use A
You can cut C and use B or A

The fan becomes unusable if A is cut

If you cut power from the fan OBVIOUSLY it becomes unusable lol

For 4 pin molex you need red+black wire (5V) or yellow + black (12V)
For 3 pin molex you need red+black wire (yellow optional for RPM control.)
