What's the best heatsink for an M.2 SATA SSD?

#1 Post by cultOfThinkpad » Fri Sep 02, 2022 8:04 am

I just got myself a T440p and learned I can fit an M.2 SATA SSD and can easily
buy a Transcend one with a capacity up to 512GB on eBay.

However, to ensure it doesn't throttle, I would need a good heatsink so
I looked online for the best M.2 heatsinks which are, of course 2280s
so I would have find a way or someone to saw them in half.

I learnt all about it here.

Though I'm wondering if I really need to settle for an expensive high-performance one or if
a cheap and cheerful heatsink off of eBay would do just as fine.

In my T440p I have one SSD in the 2.5" bay and an adapter with another 2.5" SSD in the Ultrabay.
Better value for money if you ask me.
I can't remember the last time I needed a CD/DVD (for which I have an external USB-one anyway).

In my T440p I have had a 'cheapo' KingSpec NT-512 2242 working away in the M.2 slot for well over a year now - never needed a heatsink (!)
Actually I just switched it off after sitting on standby overnight - not a fair comparison I know but all 3 drives were cool to touch (Crucial MX500 SSD main drive, rando HDD in Ultrabay caddy for non-operational archival purposes mainly - what is a CD/DVD again??). No discolouring on the M.2 SATA sticker to suggest a history of heat - but then again these modern stickers are supposed to be thermo-conductive so you *could* plonk a thermal pad/heat sink straight over it. Looking into it now, I see the issue of heatsinking M.2 SATA NAND SSD's relates primarily to controllers and not so much the NAND chips, and there is almost a fingerwidth of air space directly above the naked SSD. Without a thermal camera to support my observations I reckon my RAM cards and CPU would be far more of a concern, for regular daily driving.
