So I'm about to upgrade my PC, with a X570 Board among other things. The build is inside a very small case with similar 'sandwich'-characteristics as the Dan Case A4, meaning the backside of the motherboard sits right next to the backside of the gpu. Right now, the 'low-tier' 500GB M.2 SSD, sitting roughly in between the two components, operates with temperatures of around 55 to 70C, which is not healthy for the drive in the long run, but it shows how difficult passive cooling is in that spot. The new mainboard has two M.2 slots, one on top of the board underneath the chipset-heatsink and -fan, and one on the backside. I'm planning to install two M.2 Sata-SSDs from Western Digital, one 1TB and one 2TB. Apart from the capacity, the two drives have the exact same specs. As I have experienced now, a passive heatsink for the SSD sitting on the backside of the board is highly needed, to keep it from overheating and ensure its longevity. But, as far as I would asume, the active heatsink with the chipset-fan would still offer better cooling than a passive heatsink. Long story short, is there any difference in heat between the two drives because of their different capacities? Which one needs better cooling? Or does it depend more on usage than anything else? TL;DR: Does a higher capacity SSD generate more heat than the same model with lower capacity?
