    Crucially though, they should point out that they have a known problem, or potential problem. Missing this part out is the dodgy bit. Sorry, I should have said that to make it clearer.

    If someone then wants to buy one of these at the discounted price, it's fair enough all round.

    I have to admit reading through this made giggle like a 12 year school girl...lol

    I've worked both in a Steel Mill and at a Company Called Ajax Magnathermic which made Custom Coils For Siemans, Lincoln Electric, Erie Mining Machinery, etc...etc...

    When i first seen those Chokes my first thought was High Carbon Black Iron... Specifically the type that they use in Industrial Transformers Which after production is coated in a Clear Lacquer and upon Testing Turns from an Dark Ash Grey to light Reddish brown Color...It's not rust it looks similar but only occurs after the iron is heated and exposed to an EMF, Rust on this type of Iron is Brite Red


    This is a Picture from 2005 At Severstal Steel Warren,Ohio outside of the 56"Hot Mill

    That's not Red Paint on the Building It's Iron Rust Dust It never turns brown.. Steel rust turns Dark Brown you can see that to the right

    lmfao thats so true, poor old rusty, RIP :roll:

    On a different note, is there any actual proof that this claim is true aside from one pic and this write up on SA, tbh I think they have just got bored of NV bashing and had to turn their attentions else where to drum up hits.

    there are multiple pics, from multiple sources, in multiple languages. try reading the article, paying attention to the sources ;)

    Correct me if I'm wrong - but wouldn't that type of material not cause popcorning ("bubbling") of the lacquer?

    Not sure TBH Not even totally sure I'm correct But that's what it looks like to me....

    My Dad who is an Industrial Electrician said it looks like High Sulfur steel and probably discolored B4 it was coated ... but not rusted
    The bubbles/blisters IDK but I don't think rust would cause that

    S'all good - it's kinda hard to draw conclusions on such pics

    Rust doesn't typically cause that kind of "distortion" of any painted coating - it usually causes waves and peeling . . . only thing I've seen cause popcorning is usually the presence of a chemical or moisture underneath the coating. It bubbles the coating as the gasses are trying to escape.


    IDK - I guess the biggest point I was trying to hint at in my earlier post is that ASUS doesn't make the chokes, and it appears to have been an issue that was "trapped" when the chokes were manufactured . . . and seeing as how ASUS has to purchase the components and bring them in for board manufacturing . . .

    . . . which means, I'd bet damn good money that ASUS will not be the only motherboard manufacturer who ends up with rusting/discolored/questionable chokes.

    My guess is That Certified Iron (which is normally $8,000 a ton) is flooding the market as Mills in Pakistan,Mexico,China,USA,Japan and Russia are still making it and with reduced need The price might now be right for companies to find New uses for it...I bet the Lacquer they use is for a diff type of metal...

    EDIT: I am just guessing here IDK for sure but I don't think ASUS would use rusted metal

    What I'd like to know is why my thread title was changed by a mod? It was fine before as Avoid Asus mobos - problem with rusty chokes on new boards and I'd like it changed back.

    As usual, I didn't even get a PM about it.

    I have to admit it's a good title and pretty funny, lol. I think it may have been renamed for the gag, which isn't so bad. :)

    So, I wonder who was the enterprising mod with a sense of humour?

    Yeah it's a total PLUS message gets out (Hopefully someone effected Chimes in )

    And it's a totally Funny yet Captive Title;)

    After reading that, I think the author might be semi-dumb...

    He peels the laquer off and the rust comes right off with it. Then he peals the iron powder away from the copper coil and can't figure out why there is rust on the copper...:banghead:

    What a fucking idiot. It isn't that hard to put the dots together there...yet they fail miserably at doing so...:shadedshu

    Here is the likely issue, there was too much moisture in the air when the iron powder was applied to the choke. This trapped moistur on this inside where the powder meets the copper and on the outside where the powder meets the laquer. Rust forms in both places. Obviously the rust doesn't stick to the powder all that well, probably because it is a powder that breaks apart pretty easily anyway, so the rust sticks to the copper and the laquer. Seems like the most logical thing to me.

    The copper definitely isn't rusting, that is for sure, so there really is not actual risk of the choke failing. Also, the rust will likely not get worse. For rust to continue to form, there has to be a constant source of water and air. The laquer is designed specifically to prevent air and water from getting in the choke, so the small amount trapped inside will cause a small amount of rust, but nothing more.

    How would humidity cause that?
    The thing would have to have been sprayed by water to accumulate that much moisture.
    And have you ever tried breaking a choke? The iron is hard as rock, it's not a powder any more, despite being made out of iron powder (or ferrite powder as it might be in more expensive ones).
    Besides, things like this should be manufactured in a controlled environment, so suggesting that the environment where the chokes were made was too damp is just silly.

    I take all that back It looks like they used Iron Ore on the updated Pics...
    I don't know if that will have an effect on things but it looks and may be bad..

    But it still has a warranty right
