[scienceplease]

in the end i got 2 toshiba's and 2 samsungs.
I've done full disk write test on it, they appear to be new; it would take few months to kill them with writes to verify if they were ever used.
Additionally i've looked up similar nvme's on ebay and seem the prices are only bit higher - not in significant way.


The samsung gets so god damn hot - heatsink in picture struggles under load. (single 80mm noctua at 2000rpm blows on pcie slots).

A faster 4-12k fan should be used instead to keep it down with that heatsink for 24x7 load.

Are the capacitors on the 983a the same height as the NAND and controller chips? Wondering if anyone had to "shim" thermal pads in various places to get heatsinks mounted.

Also curious if anyone thinks it would be sufficient just to put a heatsink on the controller and leave the NAND chips bare.

they were same height

the capacitors are 0.1mm or somewhat higher, but the only thing that requires a heatsink is the controller

after applying thermal strip / paste it matters not. (The whole thing overheats like crazy in my case - but its also under lot of stress as l2arc)
