Question about Asustor Flashstor 12 Pro FS6712X

I would like to order the Asustor heatsinks for my Flashtor 12 Pro FS6712X -> M.2 Heatsinks for Flashstor (FS67) and AS-T10G3 I would need 2x 2 AS-HK1 for my device. The big problem is that I can't find the product via Toppreise or here at Digitec. It would be great if you could add it to your catalogue. the "standard ribs" are a bit too high. If I take them off and put smaller ones on, the system no longer runs stably if I want to copy a lot of files via 10GB to the NAS and crashes. The NVMe's then get up to 90 degrees, if it doesn't crash beforehand.
