[smartmontools-support] WD WD101EFBX drive has insane temperatures?

[Ed Trumbull]

I have a WD 10TB drive connected to a megaraid controller housed on a Supermicro motherboard.
The system is running the Proxmox VE version 7.2-7 kernel
(root at kvm-00:~# uname -a
Linux kvm-00 5.15.39-3-pve #2 SMP PVE 5.15.39-3 (Wed, 27 Jul 2022 13:45:39 +0200) x86_64 GNU/Linux)

This drive has been reporting "peculiar" temperatures to the syslog:

I took the precaution of shutting the system down for a bit and examining the drives. To no-one's surprise, no drive is either hot enough to bake bread nor cool enough to cool my drink.  (The output above came after the power cycle and examination.)

Are these temperature readings telling me anything that I should be concerned about, or should I just dismiss them as patently insane?
