    Some CX and TXM there. Expecting other Great Wall made units to have the same failure? Had any fail yet?

    If the failure rate looks high to you, it means that you also counted the people without any problems?

    Yeah. That's always the case. Like Amazon reviews. Sell a few thousand units, everything is great but people don't post reviews. You get two one star reviews and all of the sudden your product is shit.

    Yeah. Just testing everything made in that date range to be sure.

    When explodes, it erupt(?)s some sort of brown liquid outside of grill, and after is it dried leaves unremovable brown stain to other components around it, so many are complaing about it.

    Is the capacitor failing?

    No. It's from the insulator pad behind the failing diode.

    Is it something related to a bad insulation (electrical?) between the diode and some material next to (in contact with?) it, or is it related to a faulty component?

    Exactly. Bad insulator between the diode and the heatsink.

    From the pics posted around the net I was doubting that.
    I have seen similar spots of burn in industrial electric panels for factory machines, especially in (bad?) refurbished items where not all parts were replaced as they should have been, ending up with bad electrically insulated units (high ampere at low volts were always involved there).

    So it is definitely an installation issue in the mounting chain.

    Really hope you see my unit arrive soon. Can't share with you guys my serial number..hoping not to need to make that phone call to Corsair

    So it was not the actual diode that was failing, but the thermal pad.

    One begins to appreciate just how difficult manufacturing is and not just design.
