NAS drive overheating, what could be?

Question

Hard disks

QNAP, 8 NAS drives, 1 of the drives overheats for some unknown reason (55+ degrees, the rest 29/30).
In its place, the previous disk died some time ago (the system stopped seeing it).
Cooling is uniform for everyone, there is no heating "from anywhere"

Answer 1

write or call support. there are quite adequate Russian-speaking people willingly helping customers. there will be much more sense and faster than reading what couch experts have written for you here.

Answer 2

- Check SMART.
- Google on the topic of disk firmware, maybe the disk has a curve.
- Swap disks to check if the problem is in the disk or in the connection.
- Check disk load. Maybe all the files with which they work are just found on this disk.
- NAS's seem to put a shell on one of the disks. Maybe the system itself is spinning on this disk.

Answer 3

maybe this disk is marked as caching?
