SAMSUNG SM950 PRO NVMe SSD

curious what you're doing in the way of cooling that 950 - have you got a fan on it, or a heatsink?

Probably fan. If you perform any benchmark test with 950 PRO you must get over 54°C at some point.

P.S. I would like to see how he mounted fan, since temperature results are very stable!

Here's some temps of the 950 pro running Cystalmarks...

That's not too bad. Unlike the Intel drives at least you have active temp. monitoring. That makes it easy to keep an eye on if you do large encoding jobs or file copies, you can just pause the job if it gets too high (60C, 70C?), or add active cooling.

Edit: It looks like it took 49 sec. to reach that temp. So I'd pause jobs at around 1 min.

that's why i was asking - i mounted a small 40mm fan directly over the controller and am seeing nearly identical temps
Picture below showing the xp941 installed - it's since been replaced w/950 PRO

Post a shot of your disk layout from Disk Manager, I suspect that you will find a System Partition (100MB) sitting on your RAID Array, and that is what it is booting off with the OS files sitting on the sm951.

already posted it man , here it is again

i disconnected the other disks before installing windows because i was afraid it might mess up my data. Only the 950 pro and the usb from where i installed windows.

You can see that it is an mbr partition table, not gpt, and that both system reserved and windows partitions are on the 950 pro and the boot flag is on the 950 pro.

I had an sm951 in the past and it would neither appear in bios when listing disks nor i could boot from it, so there's something different.

No fan on it, I have a Corsair 650D with a 200mm fan in the front blowing in on the 980Ti and the 950 Pro, the fan is set at 9 volts at 780 rpms...so its almost silent....Here's a picture of the case.

 

[miki_8]

Its incredible that you have so constant temperature on 950 PRO with fan that is pretty far from it & runs on low rpm.

The 950 is in the x16 slot just below the 980Ti, so its right inline with fan! Right now my Wd Black data drive is at 32C and the 950 Pro is 41C...

curious to know from you or anyone else if there is any circuitry in the back end of that hyper card.

 

[larryccf]

not sure what you mean by "back end" - if you mean the back side, no small capacitors, diodes or whatever components on the surface

was thinking i'd wait and see if the hyper mini card goes on sale some place and do some kind of fan arrangement such as yours. Now I'm thinking I could punch some stand offs right into this larger M.2x4.

 

[larryccf]

i bought off ebay - the same seller has returned with the asus board for $19.99, and $2.xx for shipping

that's cheaper than i've seen the addonics board or the lycom dt120 board (both the same board)

Well I hit 69C running ATTO at 1 gb so I've been fooling around with a fan on the 950, here's a quick fix until I get a bracket in, I put a old 80mm fan on it and it dropped my temps in CystalMarks from 54C to 41C, my idle temps right now are 31C and that's the same has my WD Black data drive. Here's what I came up with...





Here's my last run of CM with the fan...



Just ran ATTO at 1gb with my fan setup, yesterday without fan 69C...today with fan...34C...loving the 950 Pro...

 

[miki_8]

Please show us how you mounted that fan

P.S. I wonder could 50 mm ultra quiet fan be enough for keeping temperature stable.

 

[fvbounty]

I just used a tie wrap on the fan to the pci bracket...here's what I ordered on ebay to make it more permanent....

Thank you for info

 

[larryccf]

the part that gets hot is the controller, and it's an approx 3/4x3/4" square near the end of the ssd that's mounted into the socket. The memory chips or NAND do not get very warm at all

i've been using a 40mmx10mm noctura fan and it's doing fine, ran Prime95 for 20 minutes and never saw a temp over 51C

This is now the 5th time in this thread i've posted this shot

and here's what the bracket looks like - on this one i added a short extension as the addonics board has the socket at the far or back end of the expansion board - on the asus expansion board the socket is at the other end, so i didn't need an extension - fan sits right over the controller

 

[miki_8]

I like solution from fvbounty, where fan blows air directly to the controller.

 

[fvbounty]

I did mine a little different same results what ever works...2 plastic tie wraps. Nice temps

 

[miki_8]

It could be interesting to make two little elements for fan. Whole amount of fresh air from fan could be channeled directly to controller.

I`ve made quick renders for easier presentation

 

[larryccf]

nice rendition - someone works with or in solidworks

the advantage to placing the fan parallel to the ssd is it blows air across both sides of the controller, ie front and rear

This isn't a critical heat situation, so fv's approach will work, but in general, blowing directly or perpendicular to the controller's surface will create turbulence, ie air flow hitting it will bounce back toward the fan and inhibiting the airflow, so you get a lot of wasted airflow. Look at car radiators - what's cooling the radiator is air flowing over the honeycomb of aluminum fins, ie the airflow is parallel to those small fins

i worked on a project for a water cooled airplane engine - when the airflow was more than 3 degrees from parallel with the fins (or perpendicular to the face of the radiator), water temps went up. The issue was on climbing, as when the airplane has taken off and flying to altitude, the airflow into the engine cowling is or can be as much as 45 degrees off perpendicular to the radiator's front. As that air flow breaks over the front edge of the fins, it turns to turbulence and separates from the surface of the fins, which means no heat is being scrubbed from the fins, or less heat is acquired by the air.

that and the limitation of space in my case made me mount it the way i did. If i'd have put it the way fv did, the back side of the fan would have been awfully close to the case side cover, restricting air to the fan, with the front of the fan awfully close to the controller. The effect of turbulence would have been worse

just as an fyi

 

[miki_8]

Thanx larry from very detailed comment! Here is one with integrated holder & adjusted airflow

P.S. This solution is only available with your SSD, since 950 PRO sits horizontally on native M.2

 

[larryccf]

NICE - i like

and as to SSDs in the M.2 socket - you're right - i'm tunnel visioned on SSDs mounted on an expansion card because my M.2 socket was x2 and, in addition, killed or dis-abled 2 sata ports when the M.2 socket was in use

what i'm waiting for is for someone to come out with a carbon fiber heat sink - CF transfers or conducts heat almost as fast as copper carries electricity - i kid not. I'm surprised i haven't seen it employed already.

 

[Redstorm]

This is now the 5th time in this thread i've posted this shot

We know...

Everyone panicking about 60C is crazy, you don't have any issue running your GTX 980Ti at 80C

I'm not wasting the time and effort, Stuck it in the motherboard M.2 and im happy as larry.

Take a look on my renders below

I can produce something like this from solid aluminium, since I have few friends with high CNC skills, but, from CF it seems kinda challenging to produce!
