Have a look at this forum post, and this web site and also this one.
Hello, Unfortunately I didn't find a Dell Gaming Laptop category Therefore I created the article here. I ordered a Dell G15 5510 with i7-10870H and RTX 3060. Now I saw in a teardown video that there is no bracket and heat sink for the 2nd M.2 SSD. Are there already the right part numbers for it? I have already been able to locate the PXNWV for the bracket. However, for the heatsink, I haven't found anything suitable for the G15 5510. Best regards!   EDIT:  [IMAGE] Teardown Video G15 2021
