Since I was in the same situation: No. You can use the kit to install (certain) Be Quiet coolers (Dark Rock Pro 3, Dark Rock 3, Dark Rock TF, Shadow Rock 2, Shadow Rock Slim). However, the kit is not a direct replacement for the original backplate, as the cooler compatibility is severely limited. Here is what you are looking for:

However, no Swiss retailer has the product in their range and Arctic (although they were based in Switzerland until recently) no longer deliver to Switzerland since the change in the VAT law - I had also asked Digitec if they could organise the item for me as a corporate customer of Arctic - unfortunately no.

If you have money problems, here is a non-original replacement that I also ordered (and which actually arrived). It comes close to the original in terms of quality, on Amazon you only get plastic scrap replacements):

Otherwise: Return the board...
