The Accelero Twin Turbo III will not work with my current setup without major rework.
The P4000 has a primary shroud that both connects the rear slot bracket to the card & provides some passive cooling to parts on the card. It also has a small heatsink with 2 heatpipes that cools the GPU die & hangs over the VRM, but with no thermal interface material. When I got a better sense of how the GPU was assembled, I intended to just remove the heatsink & add the new one. Sadly, the mounting bracket is larger than then inset in the GPU, & I wouldn't get contact with the die. It's only about a 0.3mm gap, but I don't feel comfortable grinding down anything enough to make up the difference. Additionally, the backplate is just slightly too tall to fit under the NH-D15 even turned to exhaust vertically. I could've moved the GPU to the PCIex8 slot, but my case only has 7 PCIe slots, & the support bracket is too tall to fit in the lower slot without an 8 slot case.
Next step is to try a more basic cooler, probably the Accelero L2 PLUS since it has a different mounting bracket that may allow the coldplate to contact the die properly. Now that I understand how the rest of the card is assembled, I'm not worried about cooling the rest of the components anymore. I'll update again next time I mess with it.
