I've been looking at replacing the Intel Optane stick in my laptop with a 2TB M.2 SSD. I'm looking at a number of options but I'm worried about overheating issues. My laptop doesn't have any real cooling for either the storage devices (SATA or M.2) and I've heard that the newest PCIE Gen 4 M.2 drives can easily achieve blistering temperatures even in your average desktop with fairly spacious internal area. But in reading up on the PCIE Gen 3 drives it seems they too can easily reach considerable temperatures if not properly cooled. Not only do both PCIE Generations crank out a lot of heat but quite a few sources point out that it's worse the faster the drive, which is in turn affected with bigger SSD's. But some of the other configurations of this exact laptop (HP Pavilion 15 gaming) come standard with M.2 SSD's. So is it safe to risk putting an M.2 Drive of either generation in the fairly enclosed space of my laptop? Or should I avoid it to avoid cooking the other components?

And if I just wanted to throw Windows 10 on a ssd with everything else on the hdd, what is the minimum size ssd that you would recommend?

I left out storage as I was planning on using the 1 terabyte drive I've got in my current system. Also yes this is meant to be a budget build preferably as cheap as possible while still having decent hardware. Under $500 is best as I don't exactly have a steady or very good source of income.

I've found all the parts for a new computer but want to make sure that all the parts are compatible, and that they aren't 3 or 4 generations out of date. Anyone see anything that doesn't meet those criteria? http://pcpartpicker.com/list/Gyf9JV
