NVMe M.2 2280 SSD Heatsinks Cooler, Universal Type (2nd Gen)

What are the black circles in the top picture, what are they made of, and when to use them instead of the silver metal braces that are also shown?

Hello, will this fit a 970 evo plus on my msi ge65 raider laptop? many thanks in advance!

How tall is this with the nvme drive in it? i want to use it in a ps5 and the compartment the ps5 has is 4.33in (l) x 0.984 in (w) x 0.442in (h)

Does the blue tape stick to the paper on the SSD, and if so, is it possible to remove it later without a mark if one needs to use the warranty?
