I haven't read all the posts, so just in case no-one's mentioned it:
Drives running the 4Kn SECTOR (not Cluster) size, rather than 512e, seem to be running cooler from what I have read.
ie:
Converting your SSD to its native K4 sector size, rather than have it emulate 512K sectors may well mean a usefully cooler drive under load.
Less processing = less heat. (and less time)
Once your sector size is maxed out, know that NAND is written in Pages.
Pages used by be 4K, (the windows default) but have grown to 8K, 16K, etc.
Setting your cluster size to equal your NAND's page size may well have a similar effect.
Naturally all Partitions, sectors and clusters need to be aligned.
Thats a subject in itself. Especially as most drives now employ a pSLC cache (to spead up writes mainly), meaning 2 different Page and Erase Block Sizes to align to.
Newer Windows versions do an adequate job of alignment, but there's more performance to be had here IMHO and should again result in a bit less processing.

I'll leave it to you all to research the truth of this and perhaps experiment.
