Hello

On a laptop, is it worth using an aluminum M.2 SSD heatsink with thermally conductive adhesive foil?
Will the thermally conductive adhesive foil be effective?
Will it improve the temperature of the M.2 SSD?
Regards

It looks like the laptop supports pcie 3 so you can install the 850x but it will run at a lower speed meaning cooler.

I doubt you will need any extra heatsink.

Install the 850x in stock form and watch the temps.

Ok I will try and observe as you tell me.

A hot M.2 SSD controller can reduce performance and slow down your machine. However, before buying anything, I would download a tool called Crystal Disk Info. You can run this program to see if you need cooling in the first place. If the temperature is at 70 degrees celsius or over, it would be advised to get a heatsink, provided it will fit with the rest of the components and chassis in place. Even if it is around 65, cooler temperatures will help your SSD last longer, so you might want to pick one up even if it isn't at 70. However, if it's around 60 or lower, extra cooling isn't strictly necessary. Additionally, these heat sinks should come with some thermal adhesive tape or thermal pad with adhesive, and using one of those would be better over foil.

Understood, the Crystal Disk Info gives me temperatures of 40 and does not usually reach 60 so you tell me to put an adhesive sheet as a precaution and that fits perfectly into the chassis of the laptop would be enough.

Adhesive thermal sheet by itself will not help any unless between drive and heat sink. Typically SSDs heat up only under prolonged writing of large files, if it's an OS drive that rarely happens.

Thanks for the comment I did not know that the adhesive thermal foil had to be placed next to the aluminum heatsink for it to take effect, I am ignorantly putting them on both sides believing that they would be worth something.

Your best to have the heatsink if the bottom of the laptop has copper foil on inside of laptop use a thermal pad on combination so it makes contact. ( Some do)

It's role is same as paste, to close up the gap between 2 surfaces and small scratches and bumps as no surface is ideally smooth. It's also made to be least restrictive in heat transfer. If you were to use it without heat sink, it would be more of an insulation than help.

Hello again, according to your comment I should not put the foil unless I put it with a heatsink?
Then another question the sticker that bring the M2 of the brand of turn that also harms and should remove it?

No, not without a heat sink.
No do not remove sticker, it's metallic and conducts heat, without it warranty would be void.

One last question, if an M2 only has chips on one side on which it has the sticker, to do it correctly should I put the adhesive thermal film on top of the sticker, then on top of this the dispenser and on the bottom side that has nothing there I would leave it without thermal film or should I put it too?
Greetings

Hey there,

Eh, I'm not sure either a heatsink or thermal pad will help much. Being constrained in terms of airflow and internal cooling (in a laptop) taking the heat from the SSD and dumping it on the small thermal envelope that is the chassis of a laptop, and .......well, you can see where I'm going. The heat is just being pushed around as opposed to being exhausted. The exhausts on a laptop typically only take heat away from the CPU and GPU

It also depends on what exact SSD. PCie 3 SSD's don't run hot, even in a laptop. PCie 4 SSD's do run warm, and can get up to 70c which can cause throttling on a lot of SSDs, but moreso in a laptop than a desktop. PCIe 5, forget about it. It needs a heatsink, specially so in a laptop.

Before any more guesses, which laptop and which SSD are you talking about?

Hello the laptop is an ASUS A15 TUF TUF Gaming Laptop from 2022, the M2 I want to install is a WD Black SN850X.

That laptop doesn't support any M.2 heatsinks.
Just a thin metallic film.

SN850X is PCIE 4.0 drive. PCIE 4.0 and 5.0 drives run generally hot.
I'd suggest you choose PCIE 3.0 M.2 drive instead. For example Samsung 970 Evo.

Ok I would keep that in mind as the performance will be approximate, but I already have the unit and reading the comment below from “bob.b” the computer will bring it down in performance to Gen 3 and I will give it a try.
