sesonic 550 S12 fan control

[travistee]

I have a sesonic 550 S12.

I don't see a power fan connector to connect the mobo.

Does it monitor its fan speed itself intead of being controlled by the bios in the mobo?

All PSU's monitor their fan themselves
Some PSU's just provide a signal that will tell you what RPM it is running at

They usually have a fan connector coming out of them that you plug into one of your free mobo fan power connectors.

That way with a program like Speedfan you can monitor that mobo fan connector to see the PSU fans RPM.

Oh!

I'm a big- time Seasonic fan... I've been using them since before the Super Tornado (predecessor to the S12).

I think I know what you mean.... Seasonics USED to have a PSU fan monitor cable that you could plug into your motherboard. The purpose was only for motherboard monitoring of the PSU fan, the speed was controlled by the PSU itself.

They stopped providing that connector around the second or third generation of the S12. Right about when they sleeved the cables.
My S12-600 doesn't have one, and neither did the S12-330s I've seen or the S12-430. But my old S12-380 with the unsleeved cables- that one did have it.

You could probably put a 3-wire fan in and bring the signal wire out if you really wanted to. I believe that Seasonic had the fan signal wire and a ground wire at the 3-pin connector.

Have Fun!
