Thick metal ring in PC case?

Christo · 21 Mar 2007 at 02:28

I just put together my machine an noticed a thick metal ring about 1 inch in diameter, what is this for!?

I think it's for keeping wires together :confused:

Makes sense I guess!? But cant really see how.

It's magnetic to reduce electromagnetic radiation. Not hugely important these days, but theres no need to take it out!

Ah so you just put it in the bottom of the case, loose?

It's a RF choke, you wrap the wires from the front panel through it a couple of times. It reduces interference pickup. Any noise that the LED cables picks up could light up the LED's, so the choke stops it.

Yep, except that it is magnetic so should stick there firmly enough.

Stick it on the hard drive, it should work wonders!

Only joking by the way

You can stick a magnet from a 18" 1000W speaker to a hdd and it won't do squat.

HDD's use rare earth magnets. they are very very powerful and need one hell of an opposing magnetic field to interfere with them.

It was just a joke, we don't need to turn this into a magnet discussion :rolleyes:

So all the talk about never putting speakers near pcs is a complete load of rubbish then :/
Looks like I may do a mod I've been wanting to do of mounting some semi decent speakers in my case

More to do with magnetic shielding and monitors tbh.
