    joshindaphils, that's where I got the idea to suggest trying to install the 2.5" / M.2 SSD's Bare - without mounting caddy/plate; I finally saw a photo showing an M.2 mount on edge which showed that the bumps on the M.2 plate were at the same height as the 2.5" SATA III port - it looked to me that there was enough room to mount both drives without the mounting metal in the way.

    Hopefully the G751 Mk. II should work out all these optimizations and give us better mounting and IO connections.

    guys what temp the xp941 reach? i keep hearing that it goes far as 90c,its that true?
    that 4k writing is rubish than a 2,5"

    CrystalDisk info was unable to read the temp of the xp941, any idea what tool can?

    I did bench both drives at the same time for 20 min as a torture test, realistic loads will never be anything like this.. both drives would of been overwrote multiple times in this scenario... anyhow the 850 Evo had a peek of 68c then normalized to 62c after about 10min. When just performing the test with only the Evo temps plateaued at 60c.

    It would seem that there is little to no contribution of additional heating by the xp941. Giving an easy way to get temps of the PCIe disk I will rerun the test.

    Edit:

    Also to note idle load is 32c on the Evo.

    Still looking if anyone knows an easy way to get the temps on the XP941. Thanks, sorry for the bump.

    joshindaphils, kinda unusual for Cystaldiskinfo to fail to read sensors, I assume you downloaded the latest release/beta? XP941 is new, you could also report this to the developer of Crystaldiskinfo...

    Here are some others to try:

    http://www.hmonitor.net/

    http://www.almico.com/speedfan.php

    http://www.hdsentinel.com/

    http://www.argotronic.com/en/

    hwinfo64, AIDA64, etc, etc....

    Samsung Magician is supposed to recognize the XP941, but the utilities don't work... that might change.

    Please let us know what you find works

    hmscott,

    No love so far tried a few different tools. Don't have the time to go through the your full list as of now.

    ClinIgm,

    There are three pentalobe screws holding the drive case together two are under the drive's label, you must puncture / cut the label to get access to them. I didn't have any pentalobe drivers so I simply used a jewelers flathead on the pentalobe screws, it worked just fine. If you look at my first post there is a pic of the bottom plate that shows where the screws are. You can firmly run your finger around those areas until you find them by feeling the recess through the sticker.

    Doing this does void your warranty though, there is a nice message on the sticker stating so.

    joshindaphils, it looks like there may be no temperature sensor on the XP941 to read...

    "M.2 Drive Temperatures

    We have seen some reports online of M.2 drives (specifically the Samsung XP941) running very hot, so we wanted to see for ourselves how hot both the Plextor and Samsung drives run. Unfortunately, these drives do not have any thermal sensors integrated that we could find so we were limited to using a thermal camera to find the hottest point on the top of the drive. This is not 100% accurate since there may be hot spots on the back of the drive but it is about as accurate as we can get with current M.2 drives."

    http://www.pugetsystems.com/labs/art...n-575/#sensors

    If you put a bare 2.5" in the same bay as the M.2, carefully using strips of tape to anchor them in the bay, you could use the 2.5" SSD heat sensor to monitor both. Not you you, your solution doesn't cross the drives so the temperatures are likely independent.

    Eh I would pick up an IR thermal probe before that. I would also question any results coming from a 'tape the drives together' methodology hehe.

    Their concerns on accuracy seem a little unfounded as the heatsink side 'should' be cooler unless there is a chip with some out of whack thermal properties (controller?).

    Regardless, I am comfortable with the thermals just off my single test set and seeing very little delta between both drives being active and only the Evo.

    joshindaphils, there is no thermal probe point on the laptop motherboard, otherwise that would be better, but if both drives are touching each other - I wasn't suggesting doing it only for a temperature reading - then they will eventually equalize to the same average temp. If you know the 2.5" normal operating temperature range away from the M.2 you can guesstimate the M.2 temp contribution to the merger of the two.

    The temps reported in that article are a bit scary, they shouldn't run that hot. My Sandisk M.2 SATA III drives idle at 36c and get up to about 42c-45c under heavy sustained load, depending on ambient temperature.
