Well, I ended up returning the 970 evo plus m.2 (500GB) to my friend who had given it to me before (he gave me the 970 evo, which I RMAed and they credited me the value, and with 10 more Euros I bought the Plus which I gave "back" to him). Well and he gave me instead his old 950 Pro m.2 (240GB) which works fine in the same conditions as the 970 evo plus won't work. It's half the disk space, but at least works.

I'm trying so much because is it possible that my friend that had the previously RMAed 970 Evo has so much better temperatures inside his case than me and that prevented this from happenning even during this last summer, here in Portugal with max. 42ºC outside and inside? Damn, this Evo Plus that replaced the 970 Evo that he gave me is freezing the whole pc at around 45ºC. That's almost the temperature outside in the summer. Maybe his case does the trick, I don't know......

Lol, still trying here. I'm not being able to make it not freeze in games while having my pc case all closed. My PC case with all the covers, top and front also, limit a LOT of airflow even with 6 fans inside but only the back fan has wide holes for the air to pass. Well, I believe I will end up trying to return it, explaining the problem to them at the store because these temperatures should be acceptable in any scenario. I don't know why I'm still trying because the disk is now with a thermal pad below, and a thermal pad with a heatsink on top, which came with the pci express m.2 adapter, and it is there that I get the best temps and it takes longer to freeze, but still, it freezes........

Well, I also opened all my case, and it is solved, lol. Then I closed the case and put my fans all to 100%. Never had those freezes again.

Hi Same problem here. Samsung 970 Evo Plus 500gb. Either on my MSI z97a gaming 6's m.2 slot, as well as in a pci express adapter that I bought since eitherway my board's m.2 slot slows down my 970 evo plus. So I bought the adapter which limits my gtx980 pcie slot to 8x so the 970 evo plus on the pcie adapter card can run at 4x and reach his max speeds. The pcie m.2 adapter comes with a heatsink (cheap one) and thermal compound to put on either side of the ssd. But the cooling in my case is not so good. The case has many fans but it is too "closed" without many spots where the air can flow. The thing is when my pc freezes I don't see his temperature go higher than 58 ºC - 59 ºC (and I didn't see the temps in your screenshot go higher than that also), which was a thing that I immediately checked since there are many expensive M.2 ssd's on the market that have reported temperature problems. I only have tried (I haven't tried games with less than dx12 lol, I have to check that out) Fortnite (with dx12) and Diablo3. Diablo 3 freezes EVERYTIME after loading and exactly when/if I start to move my character. And this is literaly everytime. If I don't move, it doesn't freeze lol. Fortnite freezes a bit after landing at main menu, either on BR as well as in Save the World. Another thing I've crossed out of my list of causes is the disk itself not being in good health as many people here suggested because I went to the store and returned the first one (which was a 970 Evo 500GB, not the Plus) for the money back, and payed 10 more Euros and brought home this one, which has the exact same problem. You're the only one, along with 4nt0ch in the last post of this thread, that have kind of the same problem. All other people that I find googling this issue are people whose the PC with 970 Evo freezes randomly, and not just in games, and not just in specific situations in games where the hard drive isn't or shouldn't be reading or writing much (D3 is after the loading when I move... Fortnite freezes in the menu after loading it. Well, I'm going to try this now: remove my case's front panel and top panel which limits veeeeeerrrry much the airflow. But I don't believe it will work since here where I live it's below 10 ºC outside, and not much more here inside, and you said you turned your AC to 21 ºC, right? Before or after that I will try games that are not dx12. EDIT: Everything runs fine without the 970 Evo Plus (and without the 970 Evo previously). I mean, with Windows installed in one of the other drivers, 840 Evo or 850 Evo, and also the games in those drives.
