I just want to say that I bought these heatsinks for my NVME drives and they worked really well. Dropped my drives temperatures by atleast 7C. I needed these as my LSI controller runs hot and the one NVMe drive was right near it. When doing a parity check my LSI would get really hot causing my NVMe to get really hot. My NVMe is used for docker appdata and is not used for a cache drive.
