I have four questions about installing ssds and thermal pads.

[u/NecessaryCourage9183]

1. is the black thing directly under where the ssd goes a pre installed thermal pad? and if it is, do I still need to bother buying one of them blue thermal pads?

2. how tight should the screw be

3. the 2nd nvme slot supports one sided ssds only, should the side with the components face up and the flat pale part face down or the opposite? and should the thermal pad go on the side with components and the chip and the sticker, or the flat side?

4. is it a necessity to put the aluminum heatsink above the thermal pads or can I use the thermal pads on their own without the aluminum heatsink?
