Samsung 850 EVO SSD: observations & LL-booting problems in dual-boot setup...

[m654321]

On setups (1) & (3) in my signature below,  I replaced the HDD drives for Samsung 850 EVO SSDs some time ago.
On setup (2) I have a Crucial BX100 SSD, and have used this for comparison.

Observation - Samsung SSDs seem to overheat:
The first thing I noticed, following HDD replacement with the Samsung SSDs (250GB & 1TB), is that these SSDs run very hot, to the extent that it feels uncomfortable working with a laptop on my lap.  In contrast, the Crucial SSD gives out hardly any heat at all, the laptop chassis feeling very cool, and there are no LL booting issues [though setup (2) is an LL-only laptop].  This 'overheating' effect, in both setups (1) and (3), with the Samsung SSDs, struck me as being very odd.

LL hanging at bootup with Win8.1/LL2.8 (either with or without UEFI installed)
Second, I had a regular issue with LL hanging indefinitely at boot up in setup (1) using a Samsung SSD, though rectified this each time the problem arose, using the unsatisfactory workaround described in Section F of https://www.freecinema2022.gq/forums/tutor...y-enabled/

Originally, I had a Win8.1/LL2 with UEFI on setup (1), and at first I thought the 'hanging issue' might be due to some sort of UEFI bug.  To check this, I reinstalled the dual-boot setup, but this time without UEFI, i.e. installed on an MBR rather than a GPT formatted SSD.  However, the LL- hanging problem still persisted. Indeed, the problem only appeared to go away when I went back to using an HDD disk.  Setup (3) has never displayed any booting issues and works reliably.

Obviously, I want to return to using the Samsung SSDs in setup (1), given  their significant edge over HDDs in speed of operation together with their high cost I've invested in them...

Any advice or comments on either of the above warmly welcomed.
Many thanks in advance for any help.

I have a number of 850 Evo's
In 1 PC 1 runs at 36/37C, and I have 4 in a 5.25" adaptor, it's got an additional fan they run at 31/32C.
((NO A/C in the UK, ambient room temp is 23C))

Are you sure it's the SSD.?
Open Menu > type Disk
What does "Disk" show the temp as.?


What is the CPU temp.?, Laptops have limited cooling, so a hot CPU can warm up the HD

Compare your cpu % use between the two disks, and your graphics card setup on both. If one disk is running hotter your graphics card setup may not be correct for that one, dumping all the gpu work onto the cpu. Sounds funny, but happens more often than people think.

CPUs seem fine (about 40 C), the SSDs are

The SSD are

You seem to have missed the temp off.??
