Heatsink for gen 4 m2

[Min]

I want to buy Lexar NQ790 ssd one comes with heatsink other one without, do i even need one ? Thanks!

[_I_]

yes

does the mobo have heatsinks for the m.2 ssds?

[Min]

My motherboard is ASRock B760M , i think it have heatsink , i assume atleast

Some of their boards have them but some do not

Most SSDs don't come with a heatsink and if they come with anything at all it's not a heatsink, it's a basic heatspreader, even if it's not paper thin, a chunk of metal that lacks fins is not a proper heatsink and won't actually do all that much for cooling as there isn't enough surface area for the heat to spread out and be cooled efficiently by airflow, it's really a "better than nothing" scenario

It's not a necessity for the typical day to day user and gamers because the drive isn't going to be pushed hard enough by most daily use and gaming loads either way

no your asrock has a heatsink already just make sure you peel off the sticker on it.
and a 3rd party heat sink may not allow you to seat your gpu.stock heatsink will
be more than sufficient.

(thats the sticker/peel on bottom that sets against the m.2)

really bad advice.....more then a few will burn out if you dont use the included heat sink.....heat sinks do NOT have to have fins to do something as the metal mass maybe all that is needed to keep a device in its rated range.....dont lie to yourself....some of these drives are hitting 90C at idle.......

the only way you will know is checking the temps if the drive has the sensors......if it idles any where near 60C use the heat sink.....

First of all, that's not even close to true, I've been using PCI-e SSDs for years and never even had one "burn out" as you claimed. I've managed to run out of writes on one, but never even saw one reach the typical maximum operating temperature.

Second, a proper heat sink needs actual surface area to be effective, slab of metal that's barely more than 1~2cm thick is still just a heatspreader and will not do much to pull heat from an SSD and definitely won't cool the SSD if there isn't some kind of direct airflow to it. It's not something worth paying extra for, especially when many motherboards already include them, which is why many SSDs have non-heatsink options or don't have a heatsink at all, it's for compatibility with motherboards that have them because there are motherboards where you're basically required to use them due to how the manufacturer designed the board.
Most M.2 slots are underneath PCI-e slots and get mostly blocked by video cards, with the only real access to airflow being the video card cooler, unless the unit is liquid cooled. For air cooled GPUs, that's usually going to be fine because the airflow from the GPU cooler under load is going to be enough to keep temperatures in check for the average user, and I would know because I've ran them when they were covered by a video card and they never exceeded the low to mid 60 degree mark with an actual data load.

Third, if an SSD is reaching 90 degrees Celsius, then it would be overheating, because the maximum temperature for most PCI-e SSDs is 70 degrees Celsius, and if it's reaching over 20 degrees over maximum operating temperatures while idle, then you have a faulty drive, because regardless of PCI-e bandwidth, they will NOT idle that high when they work correctly, they typically idle around the 30s, maybe the 40s, and you would want to worry if they're in the 50s while completely idle.

NAND flash also has a higher maximum operating temperature (i.e. 85-90+) and there are cases where NAND flash can perform better when it isn't cold, the listed operating temperatures are based on the SSD controller. Some have trimmed thermal pads to focus cooling on the controller for that reason.

Only way in hell an SSD controller is going to reach even 90 degrees under load is if it's a Gen5 drive being pushed to its limit with piss poor airflow.

idle temp is meaningless

a ssd will not burn itself out,
they will lose performance when hot because they are throttling, but not burn out or stop working

they do have a min optimal temp, like most mosfets, they are not as efficient or fast when cold/cool (<30c iirc)
but with a small load they can heat up past that in no time even with cooling

heatsink does not need 'fins' but they do help, all heatsink needs is more surface area and/or more coolant/airflow then the device its contacting
