Cooler Master Centurion 5? whats the big grey ring?

[Jdm240sx]

i just got my case today and theres this abnormally large grey ring i manage to find nothing about it on the internet and it fits nothing on the case?

does anyone know the purpose of this ring?

is it rubber, like a washer? Perhaps it goes to one of the fans? Looked at all the pictures for that case on newegg, and I don't see anything that resembles what you are talking about.

It's a magnetic core, which is not the same thing as a magnet (for example it has no magnetic pull unless there's a wire carrying current wrapped around it).

You use these cores in EMI (ElectroMagnetic Interference) suppression by running wires through them. Do you have an older console system like a PS2 or original Xbox with wired controllers? They use ferrite cores (slightly different form factor, same idea) on the controller cables like the arrow points to in the picture below. You can also frequently find them on USB cables. I have no idea where they expect you to use that thing in the PC though.

It is for the front USB/Firewire ports, run the cables through the ring and back through again before pluging them into the motherboard.

i didnt do that and they still work

Use them to reduce EMI. They will work fine without it but it is there for a reason.
