Host system freezes in some hours after start and MiniPC overheats

[saneklad]

I use Proxmox quite long with mipiPC as home Pfsense router and some VMs.
But in last two days my system completely hang in some hours after power on and aluminum case overheats terribly.
When I make hard reset - everything works fine again, but the problem occurs again after a couple of hours.

I would be grateful for help where to look for the problem and how to fix it.

Spoiler: IO error from Host HDMI output

I disassembled my QOTOM Mini PC and find out this mSATA Hoodisk 256GB SSD installed

Specification says 544 TBW for 512GB
I looked into my SMART parameters:

Power on: 2 yr 10 mon. 1 w 3 days
Lifetime Writes: 885035 GiB (omg)
SSD Life Left: 92%
170 Bad_Blk_Ct_Erl/Lat: 1 / 156 (do not understand)

So the main problem is old aged ssd and big TBW?
But it works without problems from new power cycle and Temperature is 33 Celsious.
I think I need to add daemon for SMART change and logging to syslog that can help me investigate the problem.
