Uncovering the real impact of NVMe heatsinks

[@jouniosmala9921]

Lower slots typically come through chipset and share bandwidth with other periphelias and are slower. So the top most slot is the one you should use unless you know that using bottom-slot doesn't hurt performance.

[@TheProvokedPrawn]

That is true.

[@Pertamax7-HD]

nice detail sir

[@TheProvokedPrawn]

Thanks

[@MrVoayer]

Important illustration of the function and purpose of heatsinks !!!

[@MarkJacksonGaming]

-- They make a HUGE difference. I run passive heat sinks on Samsung 990 pro 2tb NVME drives. I have Acdale sinks, under constant tests with disk mark, I can't the drives over 39c. They run gen 4, Glid .5/1.0mm pads where relevant, thermal grizzly between the sync and the spreader. Also did tests first with labels on and labels off the drive. That saved me about 1c.

[@CristianCiupitu]

I think you meant Acidalie.

[@glakoblako]

Nice vid Dr. Prawn informative as always.

[@TheProvokedPrawn]

Thank you kindly!

[@unicodePug]

If you buy an NVMe drive that has its own built-in heat spreader, do you have to remove it in order to fit it under one of these built-in heatsinks, or are they built to flexibly fit the increased width caused by built-in heat spreaders?

[@Cuhbs]

saw you had the same motherboard for the first part and great to see the heatsink on it works really well

[@Liedral]

Oh, lucky... just as I start searching for NVMe heatsinks, this video comes up and the motherboard you're using is the one I have.

[@TheProvokedPrawn]

Nice

[@JB-ue6lf]

What if you're only playing games and occasionally surfing the web like KZbin? I want to buy a new ssd, but not sure if i should go with the one without the heatsink and save a few bucks. Ive heard contradictory things.

[@amateurwizard]

--READ ME-- What you're seeing is the controller thermal throttling. Flash will perform better under higher temperatures. If you cool the controller and not the flash you will get better performance. However to prevent bit rot you should keep the flash cool when not under heavy load.

[@larsjrgensen5975]

The temperature gun at 30cm away from target measures a circle of 5-10cm diameter depending on model, so you are not measuring the SSD alone.

[@TheProvokedPrawn]

Tbh the internal sensor temps are a better measure of what I'm showing anyway but thanks for the input.

[@PeterHarford]

Very Informative, my Samsung 970EvoPlus runs at about 54deg using your Methodology on Asus Mbd heatsink.

[@swizzler8053]

A heatsink is very necessary with a pci gen 5 nvme. Keep up the great work and stay safe.

[@TheProvokedPrawn]

Yeah I've got a gen 5 drive for testing but I'm not allowed to show that yet. I'll be revisiting this when I can!

[@swizzler8053]

@@TheProvokedPrawn which one? The corsair one?

[@bigpappa_]

Great video thanks for the info.

[@TheProvokedPrawn]

Thanks for watching

[@Sleepy.Time.]

it would be good to list the ambient room temperature you are doing the tests in..i got annoyed with Jay's2cents when he was doing a AIO review and going on about how great it kept the temps when i noticed on his digital thermometer that he had his room cooled down to 18c so of course he had better than expected results to make his sponsor happy

[@TheProvokedPrawn]

That is fair. There are obviously a lot of variables that could impact it which is why I did two passes. Also I live in England, so it's always cold, but it's still a significant difference. Worth testing your own system if in doubt :)

[@Beforedeth]

From my research the best method is leaving just the pad on the controller taking it off the nands and using the pieces u remove to put under the controller to the MB the nand need a high temp and the controller needs to be as cool as possible for longevity.

[@Adi_vk]

is heatsink is also necessary with laptop motherboard ?

[@coolissimo69]

Question: I am planning to use the Samsung 980 Pro it comes with the Heatsink, so is the MB Asus B650 Legend , should I use the SSD with it's own HS or the MB Heatsink.

[@TheProvokedPrawn]

The SSDs

[@coolissimo69]

@@TheProvokedPrawn Thank you.

[@daviddesrosiers1946]

Gives you a little bit of an idea of what kind of heat is being generated right at the transistors. You can kind of visualize the temperature gradient through the heatsink.

[@markotto1767]

perfect video. thank you. i always had doubts about motherboard thermal pads cause they are not very thikness and i thought they do the opposite job, but your test demonstrate they are good. is it unsafe to remove motherboard thermal pads when changing ssd ? Is there a risk to damage the chip ?

[@TheProvokedPrawn]

That I don't know but I don't think it's a problem

[@terrimalia7214]

I don't think the average user's temperature, heat sinks or not, will get anywhere near the temps you're showing - as long as they have sufficient cooling to begin with and the fans are not blocked. Thanks for the video.

[@gloriclyoko]

Very helpful video as always! Packed with content. Thank you, Provoked Prawn. One quick follow-up question: when ssd come preinstalled with a heatsink but is removable, such as WD sn850x. Would you opt for the heatsink from the ssd or the one from the board? Thanks

[@TheProvokedPrawn]

The SSD one personally. Though I'm going to test that soon too.

[@gloriclyoko]

@@TheProvokedPrawn thank you for your insights!

[@Pegaroo_]

The heatsink that comes on the WD850X has thermal pads covering some chips but not others, do we know what chips they don't want to cool and why? And should we / is it worth trying to do the same with other ssds like the 990 Pro for example? or just cool it all?

sir how did u make your task manager black?

[@TheProvokedPrawn]

Windows 11 lets you do it.

[@westfield90]

I just upgraded my 3 year old 500gb Nvme with a WD 2tb Nvme. I cloned the drive and instantly windows was freezing and random blue screens. I reformatted and cloned again and same results. Put the old one back and it works perfectly. So I’ve ordered a heat sink for the new one and hopefully that will solve this issue.

[@JordanG2024]

Can you use a M.2 NVMe that has a heatsink with a motherboard heatsink?

[@TheProvokedPrawn]

you can't usually use both. If the NVMe has the heatsink already installed, then rely on that because it's probably superior to the motherboard one.

[@tanmayhembram9249]

perfect wanted to see a ssd for temps due to heat sink also a drive without heat sink.

[@martinarscott3524]

I've just ordered a Gen4 drive but my motherboard only supports Gen3 so the drive will be running much slower than its max speed (it was the cheaper option surprisingly), should I still use a heatsink? thanks

[@TheProvokedPrawn]

Yes

[@FrenchFries235]

I tried to install the heatsink that came with my Gigabyte motherboard and it almost broke my nvme.

[@TheProvokedPrawn]

Really?!

[@codelinx]

I watched another video that stated that cooling the controller and not the nand helps more than cooling the whole nvme ....

[@MrKZdemos]

all of sudden my waterblock doesnt seem to crazy

[@TheProvokedPrawn]

haha.

[@andrewphoto4750]

perfect timing tbh i have 1 heatsink wd drive so i had to take of my mobo heasink shield that COVERED 3 slots the other 2 are free

[@mb-electricalservices]

How about doing a video on how to get that Corsair AIO display to actually work and not show a red triangle all the time regardless of how many rimes you treble check your wiring, uninstall and wipe all traces of the software from your pc etc etc......that would be lovely...👍 Other than that rant, love your content.....that voice of yours is something special. 👌

[@TheProvokedPrawn]

Sorry to hear you've been having trouble. I'd recommend uninstalling iCue completely and downloading the latest version then check for firmware updates for the Commander Core

[@mb-electricalservices]

@@TheProvokedPrawn It's ok bud. Just a little rant really. When you invest thousands into a new rig and such a simple but handy thing doesn't work, it kind of upsets you a wee bit. I'll do as you suggest. Thanks for responding. 👍 Mike.

That’s how mine display is when the PC is off with the power plugged in

[@vinland98trance]

After I watched this video, I tested my PCI 3.0 Samsung 960 EVO 250GB with Crystalmark. I dont have a heatsink on it. The temp quickly got to 68 degrees on the NAND and 90 degrees celcius on the controller. Didnt think a PCI 3.0 drive would get that hot...the speed is about 3500/1500

[@johnpaulbacon8320]

Interesting

[@befine1304]

Is it okay to install a motherboard heatsink on an SSD that has a heatsink if you have more space ?
