Can’t you put a heat dissipator on your SSD ? And I know you said you don’t want to buy any new hardware but if you want to throttle your SSD you Might as well buy an HDD. It’s not that expensive.

Seconding the heat dissipator. This is the easiest option, you can usually just rip it off any electronic scrap you may have laying around or can find easily, and while it would be nice to have new thermal paste, you should be able to just salvage whatever is still stuck to it. It’ll work well enough for a while. As an alternative, you can throttle disk read/write speeds. Just not globally, not really. Option 1: Cgroups. Depending on distro you either already have some cgroups set up, or you should be able to set them up; and then just set max read/write speed for each group. After setting control groups you can wrap your command in ionice to set the command to that group. ionice -c3 Option 2: If you only notice this during file transfers and not during normal tasks, use a compatible file transfer application that lets you limit bandwidth, for example for rsync: rsync --bwlimit=1024 source/ destination/

The other person said heat dissipator. The usual phrasing is heatsink. Your nvme is gonna have a four digit code like 2280 following the m2 designation. The last two digits indicate the length. If you cannot see the code or look up the product description then you can measure it. If you can’t measure it then you can instead look at the supported nvme form factor documentation for your case and ensure it meets the 2280 constraints. 2280 is the biggest m2 nvme ssd size so if your case supports it you’ll be fine. Make sure it’ll work by looking first, but five bucks will get you a passive heatsink that will probably keep you in good stead over five minute transfers and twenty bucks will get you one with a little fan on it that will make sure you’re golden even during extended transfers. Post the case model and I’ll look up what will fit in it with links and also see if there’s a good spot to sneak a fan in.

Which case is it? Which nvme is it?

isn’t the whole case hot? Usually motherboard has sensors for monitoring the case temperature and control case fans. If the whole environment is above 45°C it makes everything hotter. If you can check that an easy test would be to disable you CPU boost. I always do this anyway as boosting is a temporary way for a CPU to squeeze some extra performance at a huge energy/temperature cost. On my stress test this “only” get 10-15% more performance but without boost the CPU temperature never get above 50°C. Because the CPU is not warming the case anyone everything is cooler, how much I don’t know though. Hopefully this could also reduce I/O on the SSD in general too but a cooler case is definitely better for every component. The way to disable boosting depends on the CPU model as a starting point you can check wiki.archlinux.org/title/CPU_frequency_scaling#Co….

like others have asked, what case/mobo/SSD brand? is the SSD on the front side or back side of the mobo? sometimes what I do if the SSD is on the backside (and theres no mobo tray cutout), is to get a nice thick 10mm+ thermal pad and have it transfer heat to the motherboard tray. if you can't get airflow or fans to where the SSD is, your best bet is to try yo transfer it somewhere else (aka case). you can actually get copper heatpipe assemblies of different sizes/lengths/angles to help transfer the heat

Slap a thermal pad and a heatsink on that NVME and you should be fine, provided the rest of the case isn’t overheating.

As others have said you need to heat-sink it. If the inside of the case is getting too hot as well then you need to try to heatsink it to the case itself since that’s meant to act as a heatsink. Without airflow you’re going to have issues no matter what. In general to keep NVMe heat low you’d want to choose gen3-4 if possible as those run cooler than gen5. You’d want to choose one with DRAM built in rather than a pseudo-SLC cache which will heat up the drive dramatically when it’s hit. And you want a heatsink on the drive itself. Obviously you already have the drive but something to keep in mind for future reference. There’s a lot of options for heatsinking including large aluminum heatsinks you can buy with thermal tape that can attach to the outside of cases. The problem with that in your particular instance is your case has fins so the contact area between such an external heatsink and your case would be bad and you’d need to jam thermal putty in there and probably still get mediocre performance. There are mini-peltier pad elements you can buy cheap bags of which you hook up to an appropriate DC or AC power supply which you could attach to the outside of this case as well to directly cool it by drawing the heat out and apply cold. Here’s an example of one prebuilt with a fan and USB connector: www.amazon.com/…/B0CFK73LY7 But these do use electricity to run so they reduce the efficiency of your mini-PC and you still run into the problem of the fins on the outside creating very poor heat conductive contact. Generally you want to avoid those kinds of passive cooling PC cases. Even the well built ones suffer heat issues for various components. They’re really meant for low end projects like running a display in a mall that shows a map and does basic tasks on a mini OS. Not for running a PC you’re regularly reading/writing files from. One last thing. Unless that’s a reversed fan (unlikely) you really want it blowing air on the case not trying to pull air away as you have it. It’s much more efficient that way in most cases. There’s not enough clearance for it to be a very effective puller fan. So in my opinion try reversing the direction you have that fan mounted.

i had a similar setup and i drilled a hole into it and put a tiny fan on it

You’ll never get good balance with that case as you’ve explained yourself. If you can, remove the lid and run like that, or I’d be cutting big holes in it until it’s just a chassis. If you have cats/kids and need it protecting, maybe put it in a normal PC case. I’ve run a lot of machines naked and they breathe a lot better.

You need contact in between the SSD and the case. Most cheap mini PCs like that don’t cool their drives well. You can try getting thermal pads to make good contact between the SSD and the case. Or if it’s too big and you’re stacking multiple then get a block of copper and put it in between. Also make sure there’s something making contact between the SSD and the motherboard.
