    Maximus X Hero - SSD very hot (>70C!) - Samsung 970 Pro 1TB NVMe

    I have this SSD installed in the main SSD slot, with both the thermal pad and heatsink supplied by Asus on, and the drive (obviously) screwed down.

    The drive ("Drive Temperature 2" in HWInfo64) is hitting >70C playing FPS games (eg DOOM 2016) and then, even after stopping the game, sits in the high 60s while doing low-intensity stuff (69C as I write this post, no other processes going on, 0% disk usage in task manager). SSD hits 80C in a single Crystal DiskMark run.

    Note, I left the Samsung sticker on, as the 970 Pro uses a copper based sticker/label. Every review site says to leave it on - although I'm not sure that's the right thing to do when you then put a thermal pad and a heatsink on top of it.

    Is this a Samsung 970 Pro SSD issue or an Asus mobo issue...? Seems awfully high! Any guidance much appreciated.

    interesting. 3.0 driver for nvme and ime and chipset are install? Windows is on UEFI? on bios CSM has to be disable on Samsung nvme since use his own driver. (just check) using the sticker of the NVME is have no impact on temps issues.

    The 3.0 driver is installed. Not sure what the ime and chipset are - if they are Asus drivers then yes, they are installed. I haven't changed any of the stock bios settings when it comes to boot systems, so whatever the Hero X comes with is how it's set regarding CSM/UEFI etc...?

    I had a Hero and used a 960 Pro and temps were much lower than what you say, I use AIDA64 to measure temps, etc.
    I would say either the heatsink is not making good contact, no case airflow, error in temp reporting, faulty drive.

    1. what temp when setting idle?
    2. run your favorite disk benchmark software (Crystal Diskmark, AS SSD, ATTO) a couple times and watch the temps, and recorded speeds, does the drive slow down (throttle) when temps rise?

    Thanks, sitting here now it's 57C just browsing. Yesterday it was in the mid-60s browsing after gaming for some time (an hour+). But I've stuck a 40mm fan blowing directly on the heatsink, so that's why it's idling at 57C, not 65+.

    I'll check out crystal to see if it throttles, but it almost certainly will be. I have some of my own SilverStone m2 SSD pads which I'll use to reapply and take off the asus stuff.

    I don't see those sorts of temps in any of the reviews for this drive. All the reviews have temps in the 50-60s under load.

    all the reviews are fake / incomplete, they don't tell you the whole story. there are two temp sensors.
    one is on the mem chips and the other one on the mem controller.

    and they probally don't even speak about it. that mem controller easily gets 90+ under benchmakrs tests if you don't use a heatsink.

    my idle temps



    and here are the temps after 2 samsung magician benchmarks runs:


    73 deg. and thats with a Maximus X Hero Heatsink on it. without it it would be 100+

    Many thanks for the information, I very much appreciate your response and sharing your data! My SSD tends to idle in the mid-high 50s or even 60s.

    I think I've substantially improved the situation on my hot 970 PRO M.2 SSD. I removed the Asus stock thermal pad and replaced it with a 0.5mm SSD thermal pad from Silverstone. Further, given two of the chips on the 970 PRO sit marginally lower than the other two, I put on a second layer of the same 0.5mm thermal pad on top of the lower profile chips. This brought the thermal pad into more even contact with the Asus heatsink.

    Now when I run CrystalDiskMark I peak out at around 56C rather than 70+C. And after intensive usage, the SSD drops quickly back down quickly and doesn't stay idling in the mid-high 60s anymore. Pleased with that result - hopefully it helps someone else some time.
