    Capacitor detached from PCB – RTX 2070 Super Founders Edition

    Title:
    Capacitor detached from PCB – RTX 2070 Super Founders Edition

    Description:
    During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
    I did not notice it detaching, so I am unsure of its original location on the PCB.

    Procedure performed:
    - Removed backplate
    - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
    - Reapplied thermal compound
    - Reassembled card

    Observed behavior after reassembly:
    - GPU powers on and operates normally under load
    - Furmark 2 stress test ran ~20 minutes, stable, slightly higher score than before cleaning
    - Temps: 86 °C core / 99 °C hotspot
    - However, the "GeForce RTX" side LED did not light up

    After shutdown and disassembly to verify fan/LED connector seating, I noticed the capacitor on the desk.
    I have not powered the card on again since then.

    My assumption:
    Since only the LED stopped working, this capacitor may belong to the LED/boost circuit.
    However, I cannot identify the exact pad location or value.

    Attempts so far:
    - Compared PCB photos with images from TechPowerUp (and my own board), but could not identify missing component
    - Aware that the 2070 Super FE PCB shares layout similarities with the 2080 FE

    Request:
    Assistance in:
    1. Identifying the capacitor type/specs
    2. Locating the exact position on the PCB where it belongs

    I have little experience with board-level electronics, schematics, or boardview tools.
    Any guidance would be greatly appreciated.

    Thanks in advance.

    on the back of the board,
    where it says "made in china" there are 2 holes - look below the second one

        Thank you so much. You actually found it! That was so fast.
        I have 0 experience with solder, would it be a stretch if I asked you for a beginner friendly tutorial on how to solder it back?
