Question Shocking Temp Samsung 970 EVO

I pulled this 970 Evo 512GB out of a NAS (used as a useless cache) and installed it on a desktop. Ran a quick CrystalDiskMark and I could not believe what I was seeing!

I have two of these, and the other one is not this hot, but still hot. (More like 75C max) Had to order M.2 heatsinks. I had no idea these things run this hot.
 
No wonder there is a market for NVME heatsinks. A quick look at Amazon proves a thriving market. The thing is though, how do you install a heatsink when there is a warranty sticker on top of the chips? On top of the sticker?

Peel it off and put the HS on and void your warranty in the process.

Proper ventilation tough keeps your warranty intact. Personally though I think NVME HS's are a sham anyway as unless there's direct contact between the drive and the case it's not really doing anything. Now, there's some that look like a blower on a car hood that might actually do something but the stupid silicon pads and plastic fins don't do much.

NVME drives though need to hit a certain temp to work anyway. Could try updating the firmware to see if there's been a fix that drops the controller temps. Phison had an issue with their controllers in the past and updating them to FW 12.3 fixed a lot of the issues but mostly improved the drive speed in the process to what was being advertised.
 
Well, the heatsink came and I tore the sticker off. Warranty be damned. Temp during/after CrystalDiskMark w/ heatsink is unrealistic though. I am not sure whether I can trust it. 49C max. For realz?

Touch the heatsink while running the benchmark. If it gets too hot, the heatsink is working.
 
Oh yeah it is scorching hot now. I guess the volume of copper is big enough to delay the temperature rise. I ran CrystalMark 3 times in a row with 8 GB dataset and now I see 66C max. It was 49C after the first run. I suppose this is a decent improvement.

A single run typically doesn't hit the max temp. Running a series of 10GB tests will give you the max temps though. Now, IRL though you won't be pushing enough data to hit those temps. The biggest loads loads are during boot and loading a game for the average person and those are 10-45 seconds at most. An 18 degree drop though is significant by any means or measurement.

It's actually 45 degree drop for the duration of CrystalDiskMark. (From 111C to 66C) I was thinking of running VMs on these, do you think it is a bad idea? Or was it, at least without heatsinks?
 
Yes, they can get hot. I don't run CDM, but did eventually notice that the one I had added had high temp.

The M.2 slot was just under GPU's PCIe slot, so the cooler of the 3070 was "conveniently" blowing air on it.
Heated air. Being covered by GPU did not only block cooling airflow in the case from touching the EVO,
but also did limit the size of heatsink one can put on.

Entire PC case needs to be redesigned for better cooling of these components that are most likely never going back to being easy to cool.

It's more that the mobo needs a rethink. Putting the M2 sockets somewhere else would be a better idea. Putting them in a line across the back by the slots or clustered in the bottom slot area would allow for better temp management.

One thing nice about physical health sink plates covering them. If they're clustered together I can see a way to make a cooler that fits a standardized add on cooler that fits a section of M2's.

By design there's 3 M2 slots in red but, if OEM's took the orange area or bottom 2 slots and made it into a cluster that's standard you could fab a heat sink for 4 M2's and keep them away from the heat producing CPU / GPU area and keep them cooler. Losing those lower bandwidth slots wouldn't be a huge impact either. Also, since all OEM's use the lower slots for lower gen cards anyway it would free up some lanes for use in the other slots. You could still manage to fit 4 cards onto a board for use. Or some people would still be able to get dual GPU's into that space if they wanted to.

There might be some complaints about how long the traces would be to the M2 complex but, if they did it right they should be able to pipe in enough high bandwidth paths to that location to hit the CPU. Otherwise move the chipset from the right side to another location and orient the M2 complex there.

Excellent idea! But I'm afraid that cluster of M.2 slots would need to be on the other side of the CPU since they need to be close to the CPU. There just isn't space around the GPU slot coz everything there is just too crowded. Or they could put the GPU slot on the backside of the mobo. In any case, the ATX form factor is insufficient for the current thermal profile of enthusiast components, let alone future needs. They need to create something called Ultra ATX.
 
@igor_kavinski Or they just need to spend the extra $2 on copper / gold to make it work. Move the heater GPU to the bottom slot and put the M2 complex in that spot then. Either way it's time to rethink things and just make it work.

Even if you have to go medusa and use cables to get those high bandwidth to different regions it's better than having to put up with some of the odd options they come up with.

The only issue that comes up is case design having the slots in the back for the GPU and other cards. But, there are riser options that allow going from horizontal to vertical mounting of things and slots that allow it.

They need to take the chiplet approach to board design like Intel / AMD are with the CPU itself. Shuffle things around and get more performance instead of just swapping out small pieces with each refresh. They've gotten lazy and complacent with things over the decades.
