RX 9070 XT Hellhound + Pure (14782) rear bracket

[caronen]

Hello,

I've purchased a RX 9070 XT Hellhound + Pure (14782) waterblock for my Sapphire PULSE AMD Radeon RX 9070. No special issues mounting the block but I have a doubt concerning the rear bracket (IO-shield).
The manual doest not specify what washer is to be used underneath the backplate in order to get a correct spacing (here are two : "M" 2 mm thick and "N" 1 mm thick. The manual does not specify which to use with a 9070 Pulse but I went for M (2 mm) as this is indicated for 9070 XT's from Sapphire.
The problem is, the washer is too thick, the backplate is clearly bent when using it. Washer "N", however, seem to fit just fine. Is there something I'm missing or is it an error in the manual ? (I've used the Alphacool IO-shield as indicated for Sapphire cards but the original one seems to be the same thicknes if not more).

Thanks

Have you checked the online maual: https://download.alphacool.com/manu..._XT_Hellhound__Pure_with_Backplate_Manual.pdf

Here you can see what kind of washer you have to use for the Pulse /Pure:

Hello, thanks, yes I've checked online manual, is the same as printed version that came with the block. The problem is that it does not mention specificaly 9070 Pulse but I would assume that It's the same washer as for 9070 XT. I've used the 2 mm washer as indicated but it is too thick ! 1 mm (for Hellhound/Reaper) works fine. Moreover, since the backplate and IO-bracket are the same for other Sapphire cards (Pure and Pulse), I would guess that 2 mm won't work on these cards either... I would assume a simple error with the manual, but the question is, what the 2 mm washer is for, since it can't be used with any card...

For the Pulse, it’s supposed to be the 2 mm washer. Together with the slot bracket, that makes 3 mm, which matches the distance between the backplate and the PCB. Please post a picture of how it looks on your side. We’ve had all these graphics cards here, and the coolers were mounted on all of them. That’s why I can’t really understand why it wouldn’t fit in your case.

This makes sense but there is already a standoff machined on the backplate and it seems to be 1,5 mm thick. Together with 1 mm washer and 0,5 mm IO-bracket it fits perfectly. Can it be I've got a wrong backplate ?

Anyway, I've finished my build and the card seems to work fine as it is (GPU hotspot 55 °C at heavy load). However, the backplate is too thick and I had to trim two RAM slots. Also, the RGB led cable colides with chipset heatsink, I've had to remove the LED strip.

It sounds like the manual might have a small error or a general guideline that doesn’t perfectly match your specific card variant — using the 1 mm washer (“N”) if it provides a flush, non-bent fit is likely the correct choice in your case.
