The asus maximus x hero has two m.2 slots. One has a angular heatsink with a thermal pad underneath and the other has an optional 40-50mm fan attachment. Which would run the coolest/provide the least throttling? The heatsink one or the other with a fan attached? Could I test it out, switch positions later easily or not? The m.2 drive would be the boot drive and only drive for now. Its going to be used for photo editing so I want the best performance possible

I would say which ever slot that has the most airflow, a passive heatsink will help until the heatsink is saturated or until the heatsink is the same temperature as the drive.
I have my drive in the top slot under the heatsink and have no issues, about a month after purchase I set a little 40mm fan on top of my Video card blowing directly on the heatsink and lowered temps of the drive another 5 to 10 degrees
You can move the drive after OS is installed without any issues so testing yourself is always the best option

Use the bottom one.
Do NOT use the freaking stupid shield.
With your X hero you got a small 40/50mm fan bracket. Get a quiet fan and mount it above your bottom M.2 slot
With the shield in the top slot, a Samsung EVO 960 nvme always throttled, reaching 60+ deg. Celsius. Thus, lower speeds.
Without the shield and the bracket+40mm fan, the drive sits happy between 27-30 normal use. On a large copy, it might go to 34-35 Celsius.69668

Deepcuts,
That fan bracket looks very nice, I just set a Noctua 40mm fan sitting on top of my Video card in front of the M.2 heatsink and get about the same temps
To be honest I didn't even look at the fan bracket just assumed it wouldn't look as good as it does, I may reconsider

I'm using the top M.2 Slot with the heatsink and the temps on my M.2 drive is at between 38c & 42c. And this is during Summer heat as where I am at the moment. The Temps may decrease a bit during Winter.

Now run a test on that drive. Do a large copy or a benchmark. Let me know how that goes for your temps.
Just remember, most if not all M.2 have a memory controller temperature sensor also, which usually runs even hotter. Use hwinfo and see your Drive Temperature 2 going through the roof. Some users report 100 deg. Celsius and over.

I'm using the top slot with the heatsink installed, my 960 evo 1tb never goes above 50c when benchmarking it (aida64 and passmark disk mark)

if I just game, browse and stuff like that it usually stays around 37-42c (according to HWMonitor)
but then again my benchmarks usually end around 2800 read and 1900 write, which is 400 less read than where it's supposed to be at, dunno why.

My CPU and GPU is watercooled though, no idea if that affects anything, I have a 240 radiator in the front blowing air in to my case and a 360 on the top blowing out

o_o well thats not happening to me. To be honest, I heard really good reviews on the heatsink for M.2 provided by this board by Asus than Gigabyte or MSI. I think it was from Tiny Logan or Pcper (or something rather) was pointing out how good the M.2 heatsink gives in temperature (from these boards) than the other motherboard vendors.

Anyway, there could be alot of factors into play and why we aren't experiencing high temps that your experiencing.

I know when I installed mine, I make sure the thermal pads are making good enough contact as well, when mounting it.

< I think it might be better off not to go too much hating on the heatsink to much on the Rog Boards. (on the top M.2 slot) >
What I'm trying to say is, i would hate to see you get flagged by others that dont agree with you, then a debacle fight comes loose. I'm not like that, but I have seen it happen before, where one and the other just don't agree with each other. (and biting each others throats)

All i can say is, just monitor your temps and if its not working for you, then dont use it :), if its working, no harm to use it . Like if the drive is going over 100c, I'm sure the drive will crash and unable to use Windows/application in use properly. If I notice anything like that, that would be my first check up.

It wont harm for the new builders to try the first slot anyway, cause it may work for them.

I also know the Top M.2 slot is configured differently than the bottom one. (where the top one only disables one Sata Port while the bottom one disables 2 Sata ports)

But of course you can configure it to either PCi Mode. Just as long your not losing any of your devices that are in play on the PCi express slots or what not :3

@izzyreb02
1.Top M.2 does not disable any SATA ports. Only bottom one when configured in X4 mode.
2. "and biting each others throats" do not have a clue what are you talking about. Nobody is fighting anybody.
3 At 1 GB/s read and under SATA III writes I would not expect high temperatures either, but then again SX800 should be 2500 read and 1100 write per http://www.adata.com/en/specification/423 so maybe your drive also throttles?

@el_terrible I also had the same speeds in the top slot, with the heat shield.
Want to get the speeds you payed for? You know the answer.

-sigh- the reason why my bench mark is like that is because i was stressing it with Aida64.. Dont tell me you didnt notice that. When you benchmark and stressing it, of course the benchmark scores will go lower due being hold back (I only started doing the stress test while it was doing the 2nd phrase with Aida64), due to stress test. But of course my M.2 is a 128GB, so Speeds may vary.

But yes your right on one thing though, that is the Bottom M.2 Slot configuration side of things.

"In the Manual if you leave it on default the Top M.2 Slot will disable 1 Sata Port on the bottom. (In SATA Mode)
The Bottom one disables 2 on the Sata Ports (SATA Port 5 and 6 will be Disabled). Thats if you put it on PCIEX4 mode on the bios."

To me personally, it seems like your the one going all out on us (and it feels like your pointing fingers at us as well lol), since you see us not having the same kind of issue that your having with the top slot. (in regards of temperature)

I get a feeling that this topic is going to end up in an arguement manner (eventually), if it doesnt end soon.

I'm just the kind of person, that just let people use, on what they wanna use (as long it doesnt harm their system lol).

But of course, If they use something that I dont agree with, I tell them once only. (unless i've been proven wrong) If they don't want to listen, I just let it be and leave it alone.

I did not notice the aida stressing.
Never crossed my mind to do a SSD benchmark while stress testing my system. And never seen anyone else doing it before :)
Can you do a proper benchmark (without stress testing) of your drive while monitoring your temps and post the results?

More in-depth testing regarding M.2 shields:
https://www.gamersnexus.net/guides/2781-msi-m2-heat-shield-increases-temperatures


Regarding SATA1 being disabled while settings M.2_1 in SATA mode, you are right. But, it never crossed my mind that anyone could use a high end board with a low end SATA M.2 drive, thus, I was thinking about a "true" pcie device. My bad.


Off topic:
I do not know why you feel attacked. I am just stating facts, as I see them and as I test them and I am not attacking anyone.
If anyone has another point of view, I always welcome those who can prove me wrong with tests and screenshots.
And with this, I hope you can rest assured nobody is fighting you. Just facts matter.

Please post some info and links so we can see the truth about some users reporting 100 degrees. You know what i think? You are full of rubbish and have nothing to back your hillarious post. You just WANT to be right - but if someone disagree, you come up with some stupid claims.

I have M.2 installed on top slot and my M.2 is around 30-35 degrees idle, and 50-55 degrees on heavy duty (benchmarks) If you have 100 degrees you have no airflow at all and need to read about how to cool your system. No one have 100 degrees on top M.2 slot....no one! Do you really think ASUS will make a highend motherboard and do something stupid ingeneering with M.2 slots?

Please stop being a smart a*s.

I did some testing around this. In short, all things being equal I was seeing 2-4c less in the top slot with the heat sink on. Some details on my config and testing.

I have a Maximus X Hero/i7-8700k I swapped into an existing z170/i7-6700k build as a rebuild. I initially moved over an EVO 960 1TB to the top m.2 slot. I started running into capacity issues so I ordered a 960 Pro 2TB.

Initially I put the 960 Pro in the bottom slot and then cloned roughly 900GB of data from my 960 EVO to the Pro. Temps topped out at 52c on the bottom slot (Pro) and 48c in the top slot (EVO). During idle the delta was only 2c.

Once the clone was complete I shut down and swapped the two drives and ran some more sustained copies between the two to gauge throughput and also to test temps. I again saw almost the same in reverse, the top slot was roughly 3c less under load and 2c at idle.

And a 100 deg. Celsius for your pleasure: https://www.youtube.com/watch?v=3hhdWwvh5kI
You should also learn that most M.2 ssds have a controller sensors also, as I stated before (but who has time to read), that runs even hotter than flash itself. When your flash is @55-60 deg. Celsius, your controller is baking :)
If you are happy with your temperatures, by all means, use whatever you wish. I like to treat my devices nice and keep them cool, while at the same time not standing near a vacuum cleaner level of noise (read tons of fans at max)

Just thought I'd mention that there is a strip of plastic on the blue thermal tape that needs to be removed on installation in the top slot. When I installed my SSD, I removed that plastic strip and removed the SSD label so the blue thermal tape made direct contact with the SSD chips.

I feel the need to contribute here:

-stay away from the adata active m2 cooler, it's a piece a s**it, vibrates from all the corners and the LEDs heat it more up
-ROG bracket cooler from the MB decreases with around 3-4 Celsius the load temperatures if used on the M2_2 (bottom slot) though in continues heavy load that difference tends to decrease

I for one found the best solution, bought an EK M2 black passive heat spreader and placed a noctua 40mm fan on it, I took off the label from the SSD top chips and now in stress benchmarks on a 960 I have 62-64 max temps, load/games operation does NOT go over 57, this is what I recommend at this point in regards to this topic.

Wow I never break 35C with a 40mm Noctua mounted directly over my NVME with the mount that came with the motherboard.

Different strokes for different folks. I was seeing idling temperatures around 38 and in the mid 40s under heavy read/writes. I went the simple route of attaching 10 MM fan to the top of the OEM heatsink (Maximus X Code), blowing across the heatsink. Now idling is between 30 and 32 and the maximum under heavy load is around 35.73682

960 EVO temperature at the bottom of the AIDA64 sensor panel.

My idling is normally around 30-32 and max 35 on load. I am using 370-e the Asus stock heatsink is cool and i believe many are using samsung nvme. Is that fact that more write speed the more the heat generated . I hope its not the same case with my ADATA still read and write is good 2.5gig read avg 2.1 and 1.1gig write and it averges 800-1gig . SO some basic issues with type of nvme we use. Try to have a 40mm fan which can be mounted onto the bottom of the board per including fan holder.

This is good advice. A couple questions:

1- how did you attach the fan to the EK heat spreader?
2- did you put the fan in push (air toward the EK) or pull (air away from the EK)?
3- how quiet/loud is that specific Noctua fan?

You need to learn something about airflow. Nothing wrong with the heat shield on the m.2 device on top. Why in earth do you think engineers are more stupid than you? My temps on my M.2 device with the heat shield on is around 40- 46 degrees....50 on heavy duty.
So it's not stupid at all- You just need som proper airfflow - simple as that.

My 950 PRO was idling at ~46C and maxing out at 65C under heavy stress test. I had been using the heatsink that came with the ASUS Maximus X Hero motherboard with the SSD installed in the upper slot just below the CPU.

I just installed the Advancing Gene NVMe M.2 SSD Cooler Heatsinks with 20mm Fan
https://amzn.to/2J0RS0G

My idle temps are now 42C and maxing out at 56C. So that's a pretty good improvement (keep in mind, I already had a heatsink on it, so this is an improvement over and above the existing Asus heatsink, so that's a 9C improvement, not bad, coming from no heatsink, I'm sure the improvement would be way more dramatic).

The tiny fan on the heatsink runs at 5000-8000 RPM, I control the speed using the Asus Fanxpert and normally idle at 5500 RPM (60% duty) and it is completely quiet. I can hear a slight hum at higher RPM, but that rarely happens. The downside is there is no way to tie the Fanxpert control to the SSD temp, you have to use CPU temp as the trigger, I wish we could select the SSD temp as the trigger for increasing fan speed.

Note that I run my case fans at a very low 700-800 RPM to keep the noise down. I'm sure if I bumped up the airflow in the case, the temps would be even better. But for me, this is a good balance of noise vs temps.

I ended up buying this guy here. The only things I didn't like were that I had to drill mounting holes for my fan, I had to trim a little off one tab and I wish that it was a little taller.

Can you take a picture of how you set up a 40mm on the top of your video card for the m.2 heatsink. I am trying to lower my temps, with just the m.2 heatsink I am seeing a toasty temps of 43-50 which is concerning to me. I want to see how you set yours up since I have a extra 40mm fan that I can use. I bought the 3D printed fan holder and put my second M.2 on the bottom slot and it sits at 25 idles and 38 under load. So I still have the asus fan bracket they provided but it doesn't look like it would fit between the gpu and cpu. So I really want to see how you did it and possibly copy it :)

Thanks!

I have my M.2 in the bottom as the GPU can get very hot, also have plenty more airflow there
