    @Ionising_Radiation Would you please share how you get the part number M2F8R for heatsink assembly? When I reached out my local Dell rep., he replied me with the part RX1Y7 but I am not sure which graphics card it is for.

    I'm actually not entirely sure. I've asked my own Dell rep, and he responded by first saying that the part number was invalid, and upon checking again, he said that happened because the part isn't in the warehouse yet.

    Odd, because he had no problems with the graphics cards.

    Is everyone else certain? I've only received two responses thus far.

    Submitted for one RTX5000. Did not realize there was a separate thread for this till the time you PMed me and hence the delay.

    Thank you so much for the wonderful deal Ionising_Radiation. It will be great if you can bundle the required heat-sink as well, of course at additional cost.

    I have a 7540 with a factory fitted RTX3000. Any other consumable, spare, screw, gasket, tape etc. that I would need for the upgrade?

    Answers from knowledgeable members will be deeply appreciated.

    Haven't seen details on what is different with the RTX4000/5000 heatsink yet; probably the stock one will work fine but perhaps throttle the card slightly more if it isn't dispersing heat as well as the new one.

    The card should be a drop-in replacement for the 7540. However after taking the heatsink off you will need to apply new thermal paste to both the CPU and GPU. Get some isopropyl alcohol (from your local pharmacy store) to clean the old stuff off and something like Arctic MX-4 to put on in its place.

    (If you get a new heatsink and it comes with a "square" of thermal compound preapplied, you won't need to apply your own paste necessarily, but you still need to clean the old paste off of the CPU.)

    Parts YHP4Y and PR6WV are physically incompatible with the RTX 4000 and 5000: the screw holes holding the heatsink down, do not align, as they are noticeably wider apart on the two GPUs—likely to allocate the 8/16 GB VRAM and the much larger die.

    I inspect the images of both heatsinks and I guess the one came with RTX3000 models won't work for the reason that the RTX4000/5000 GPU might be displaced a few centimeters below where RTX3000 is on the DGFF card. The old heatsink may not cover the die properly.

    Let alone the mounting screws are also moved to new places. #6 (top left): probably the same, #7 (top right): move down, #8 (bottom left): move below the pillar, #5 (bottom right): from beside 3rd DGFF connector to the edge of the card. The screws to mount the DGFF card itself to the chassis may be unchanged. Hopefully, they might be reused.

    Once again, it's only my rough visual inspection.

    Alright, nevermind. I haven't seen any pictures. Need a new heatsink for sure to make this upgrade work, it sounds like.

    [Edit]
    M2F8R is it? I found it on eBay.
    https://www.ebay.com/itm/264583629858

    DBJBA is known for making, err, their own copies / non-genuine parts so I am not sure if this is an actual Dell part?

    [Edit 2]
    If the photos are accurate then it looks good, those are Delta Electronics fans and not DBJBA fans.

    You seem to have a way with eBay, I must say. :)

    Thanks for this; I'll see how much Dell quotes me for the part (I've asked for a 1-for-1 exchange), and see if buying this is worth it instead.
