Question UX3405 upgrade 1TB to 2TB

[avb2]

Hi,

I would like to upgrade my 1TB NVME with 2TB
How do I know if I should get WD_BLACK 2TB SN850X with heatsink or not? is it even supported?

I am not a gamer but I open many tabs at once

WD heatsink is better than buying https://www.aliexpress.com/item/1005006751948717.html ?

I use ASUS UX3405 Core Ultra i9/32gb:

Does the orig disk have a heat sink?

If not I would try without on the new disk and monitor the temps.
