SSD Heatsink(s) / Cooler(s) in the market that fits in our Mac Mini Dock perfectly (should you decide to get an extra heatsink)

is the silica thermal pad required? When using a WD 770 nvme drive the pad squishes a tiny bit with the lid closed - I'm concerned about the pressure on the nvme drive. Is this ok?

I only use heatsink and temperature is around 40-55 celsius. Bottom case is closed. Maybe I try add thermal paste/pad and check temperatures again.

It should be fine, Praveen. And the close contact of the thermal pad with the top of the SSD and the inner side of the cover to ensure good heat transfer / dissipation. Let us know if you're to need more clarification. Thanks~ New Thunderbolt 3 Quad Slot SSD Enclosure is out now, by the way. Check it out here: https://shorturl.at/iDKZ8
