Why is my NVME at 74°c while leaving sleep mode ?

[Goudurixx]

Hello, I just installed a crucial P5 ssd of 500go in my computer, windows 10 is on it, when I use my computer its average temperature is around 50°C, I record this information with HWINFO64. I let my computer go to sleep and when I came back I noticed that the temperature graphs of my SSD were at 74°C as far as it could show me, temperatures that immediately went down once I took the computer out of its state. Where could this problem come from? The computer is not supposed to do anything when it is sleeping.
Thank you in advance for your answers.

Have a heatsink on it?

Nothing on it

Get better cooling for your NVME drive ? ( like suggested above if that's possible ), improve the air flow around problem area.

Sabrent's Rocket 4 Heatsink is pretty sweet, although this will only fit on the lower side of the motherboard.

nvme drivers run fast & hot, make sure to install a heatsink or at least give it some fresh air. Btw motherboards with m.2 slots usually come with 1-2 heatsinks included in the box.

This is actually on the back of my sf ITX build where I didn't find any cooler that fit for now (gonna put a piece of metal of the good size to make contact with the case, it should be sufficient) but the problem isn't temps under load, they are good, the problem came when doing nothing the disk will go high temp for no reason whatsoever

The computer is not supposed to do anything when it is sleeping.

But it is doing a lot when it is waking up from sleep as well as going to sleep.

My theory is when you put the computer to sleep, the contents of RAM are written to the drive. This is thanks to Hybrid Sleep(which is on by default in Windows). The writing to the drive causes it to heat up. HWInfo64 is recording that. Then the computer goes to sleep, and HWInfo64 is paused with the last reading. HWInfo64 picks back up when the computer wakes, and the sensor is cooled down in the drive, so the temp immediately drops back down.

You don't need a heatsink on an NVMe drive. They have protections in place to make sure they don't get too hot. It just helps with performance, because the drive will get slower when it gets too hot. But you won't likely notice the performance loss.

Your fans may be slowing down/stopping when you put it in sleep mode, so that could be reducing the airflow in & around your drive, which obviously would cause it's temp to rise, and then lower again when the fans ramp back up...

Also try checking all the settings in your power plan to see what components are actually sleeping and which ones aren't... you can choose options for each category & set them accordingly....

That you're aware of. I think @newtekie1 is right. You need to understand what the disk usage is when temperatures are elevated. I'm also willing to bet that if it does have to read the memory state back off the disk, that it probably isn't including disk caching contents in that snapshot which means that you're going to hit the disk a little harder until commonly hit files are cached again. Also, don't most NVMe drives handle up to about 90 or 100°C before throttling?

Thanks, thats makes sense, I should learn to live with laptop temps on my disk now.

that info would of been nice in the original post hehe

Hm, it probably stored all your RAM capacity on said HDD and while waking, it moved all stored back to RAM.

Causing it to heat up.

That you were using a laptop .

They aren't using a laptop. It is a ITX build with the drive mounted on the back of the motherboard, as they stated here:

Must of missed post 6 , there fore them saying was miss leading.

After a bit of reading on it, it's known to run hot according to Toms hardware.


Maybe it's just me i know i would not be happy with it ramping up to 70+c every time i turned the PC on.

In fact i would just fully shut it down and deal with the few seconds wait to avoid it.

There used to be a setting in advanced power settings to disable Hybrid sleep.

You could opt to never turn off drives or you can disable Hibernate.

There is also a registry edit, althought I forgot the key.

My Samsung 970 EVO 1TB NVME PCI-E 3.0 runs at 50-60c which is a lot hotter then my Sabrent Rocket 4.0 2TB NVME PCI-E 4.0 at 39-45c even doing gaming and they both have the same kind of heatsink on my Asus ROG Strix B550-A Gaming motherboard so my Samsung drive most be hotter even it has a better airflow access in my Fractal Design Meshify 2 White case where I got 3xXPG Vento Pro fans in the front and 2 in the top while using a AIO which have it's rad mounted in the front.
