Top Notch Customer Communication!
I purchased an Acasis Dock (M001) for my new Mac Mini M4 and I reached out to Acasis to get advice on the details of adding an NVMe SSD in one of its two available bays. I was curious as to whether or not an SSD drive with a heatsink would fit. I received a necessarily verbose response that surprised me with its comprehensiveness. What I suspected to be the case was confirmed by Bessy at Acasis in that due to the presence of two cooling fans already, all an included SSD drive heatsink would do is cause circulation problems due to less airflow volume. She suggested that just a thermal pad would suffice. I'm so glad I reached out and was pleasantly surprised by the length and quality of the reply. Thanks, Bessy!
