The HD cooling fan had been broken so I replaced it this past weekend but it doesn't seem to have helped. Too late? Permanent HD damage already done?

This is not a crash.
The kjournald kernel process (which handles various file-system task).
You assumption that the HD went into some type of sleep/suspend mode
during write sounds reasonable to me.
124C seems -very- hot. Even during heavy I/O.
Two things spring into mind:
A. Is it a normal desktop SATA drive or high-speed SCSI/SAS drive?
B. Please post the SMART log of the drive. (smartctl -a /dev/sdX).
