Samsung SM951 SSD- it hits 85*C! Ideas to cool it?

post #1 of 6
Thread Starter 
Hey folks,

Finally bought an SM951 NVME M.2 SSD (talk about a mouthful) and when I went to install it, I copied about 100GB of data onto it. While it did that, I thought I'd pull out the FLIR One and see how it's doing.

I was shocked to see that it was the hottest thing in side my computer! SMART reported only 60C, so I'm guessing it's talking about the memory chip and not the controller.

My computer is water cooled so I'm thinking about adding in a passive heatsink. Im height limited since the M.2 slot goes under my video cards, but I found a 20mm x 9mm x 5mm on eBay for 5 bucks.

Thoughts? Any better solutions?

Here's a pic of it under load:

With these drives I also get worried. I'm not sure what temperature they are rated to handle but adding a passive heatsink and possibly a fan would do wonders. The problem is removing the sticker and "voiding warranty" on some models, I also can't remember specific models but don't these throttle performance when they reach a certain temperature?

Man something seems a bit odd to ME imo. My 950 pro doesn't get above 32c with an ambient temp of 23c when my GPUs were on air it would get into the low 50° but the 2nd card was blocking all air flow to it and it had the GPU blowing it's air on it. Try using maybe HW monitor a link is in the Skylake over clocking thread.

That's a great point. I was going to completely remove the sticker and clean it with alcohol before I throw on the heatsink. I'm not really worried about the warranty. My other Samsung drives have done great, so I'm just going to assume this one will be fine.

Both my cards are on waterblocks, so that's not much of an issue. There isn't much heat in that area so its not coming from the cards.

But holy cow, it runs hot when doing nothing too:

I've checked the calibration of the tool, and it checks out.

Known issue with this gen of controllers - they run hot and throttle under continuous workloads. Can either aim a fan at it or mount in an adapter with a heatsink. Or fabricate a 951 block and put the little heat devil in the loop. ;-)

Not a fan of laptop form factor (m.2) devices in the desktop. But, the industry appears to love it, so we're stuck with it for now. Had to pull the m.2 drive from my editing rig because going from 1500MB/s to sub 100MB on intermediate renders was a waste.

Most normal usage scenarios won't push the 951 into throttling - but where sustained throughput is required, proper cooling is also required.
