The PCIe slot seems to be a better choice.  Installing your new SSD there and only use cooling heatsink if the SSD temperature getting too hot (use Crystaldisk Info)
Hello.  I have recently received help in the Community Forum in regard to replacing my spinning mechanical HDD with NVMe SSD in M2.2 slot on the board.  (Dell Inspiron 5675 - OctalCore AMD Ryzen 7 1700, Motherboard Chipset AMD X370, AMD Taishan, AMD K17 IMC. DMI Motherboard Product 07PR60). As I am completely new when it comes to SDD and I am running into some additional issues, I would appreciate if someone would be so kind as to point me in the right direction.  I have the SSD, along with cooling components as the thermal pads, copper heat sinks kits. I looked closely at the board where M2.2 is located and there is very little space between as the Battery and RAM Modules are very closely together.  So, any of the cooling kits I purchased with probably not fit in. The manual states to place a thermal pad to the system board first. I noticed that the surface is not flat and there is a little metal piece like tiny screw, but as I looked closer it is soldered to the board, perhaps a chip to prevent short circuit or a thermal sensor. That prevents me to evenly place the thermal pad between the board and the SSD without leaving a gap, and I am not even sure if it is advisable or safe to cover the small metal object unless I cut the thermal pad around it and put one thin thermal pad on the bottom of the SSD. Then I was planning to put a thermal pad on the top the of the SSD and a copper heat sink. On the web. I noticed that all of them are then wrapped with two plastic clips, but I do not see any place to wrap it around to secure it all together. Is it possible that the thermal pads would hold it all together?  All sounded all like a simple project, but I am lost due to the space restrictions around the M2.2. I purchased good quality thermal pads, if I somehow manage to attach and close the SSD gently with the screw, could I place thermal pads on the RAM modules or just the chips on them just to be sure that they do not get in contact with the cooling copper heat sink? The other option I think I have would be to place the SSD into a NVMe to PCIe adapter which I also purchased, since in the PC manual it states that it is supported. I just do not know which PCIe slot I can use. I know that there are two long PCIe identical slots. One is occupied with the X16 Graphic card. Would the second support the NVMe SSD?  Based on the manual it should, since I do not see any other but a very short PCI x1 slot and that would do me no good.  I am sorry for burdening you with so many issues and questions I am facing with simply adding an SSD, but I would greatly appreciate any advice you might have in order to assist me in resolving my dilemma. Thank you so very much for your time in reading my message and any advice or suggestions you might have would be greatly appreciated. Thank you. Respectfully, Johan
