OK decided to some testing next day & after boot up checked drives & all were showing mid to high 20s which looked good so left on for while to heat soak a bit & now all drives showing low to mid 40s, started the installer back up and after it had installed 88GB, app crashed but checking after reboot appeared to be the Xbox PC game pass that crashed & was also known issue so applied hot fixes but found install corrupted which required uninstalling & the hottest the drive got was 48'c so well below what it was reporting.
But think there is also a bug in software as the written info shown in magician is definitely wrong as after installing 88GB it said drive now had 360GB written to it which is way out & now looking at that on the drives it seems to be 3-4 times higher than actual copied data size.
so thought give it a break to next day before re-installing but before i did i attached my heat probe & it was now reporting temps that were slightly cooler & was consistent across all 4, so NVMe would show 43'c my temp. probe would show 38'c, got halfway through install & paused as now wanted to add a 120mm case fan mounted in front of heat sinks on the pcie NVMe cards to see if this would help & well it was an amazing win as not only did it drop drive temps idle down to 30'c-31'c it also cooled the 2nd NVMe drive on motherboard as now the hottest drive was my OS drive located closest to CPU now showing 37'c. During the install the hottest the new drive got was 37-38'c & as soon as install finished drive temps dropped so quick back down to 31'c, so for me issue resolved & just need to fit 80mm fan as the 120mm is too big & 80mm should work great, just need to add maybe 40mm fan to keep the one located by CPU cool as my rig has custom water cooling loop for CPU & GPU and so have no CPU cooler fan or GPU cooler fans moving air around above the MOBO mounted NVMe drives.
So for me issue of high temps is now resolved & looks like adding decent heatsinks do work if you not already have them fitted to the NVMe drives & then add external fan to really bring temps down.

Hi all, I seem to be getting the same heat issue with new 500GB 970 Evo Plus, the odd thing as well is i've been running 2 others of these as have total 4 nvme ssd's now 2 on mobo Asus X570 ROG Hero VIII & the other 2 are mounted into PCIe cards in Pcie x16 2 & 3 sockets. Temps before i replaced a 250GB 970 EVO all showed idle around 43'c - 49'c, now i replaced the 970 EVO which was in pcie 2 socket & was 43'c - after replacing & booted up ran Samsung Magician & saw the new 970 eco + was hitting 59'c & shot up when i bench tested it which it passed. But also noticed one of the original 970 EVO + which was running 43'c idle is now like the newly added drive & both showing idle 54'c.
Something else i spotted it reports how much has been written to drive & being as this was new, packaging was sealed with stickers & shows 171GB written to it when I've only transferred 39GB so wondering if there is a bug in the software or have i been sent a refurbished unit as cant explain why it thinks 39GB is 171GB unless it was used before & maybe sent back due to heat issues.
I've got some external temp. probes which i'm going to attach to the nvme SSD see what its true temp is.
p.s. they are all running latest firmware as well 2B2QEXE7
