Hi
This is nothing to worry about and we are all seeing this issue. The problem is the number given by the drive isn't a straight forward conversion to hours, so software that reads this number gets it wrong completely if it just assumes the number is total hours, as it isn't.
The Intel tool box isn't showing hours, but the raw SMART data, so technically it isn't misleading you, as the raw data often requires converting or interpreting to make any sense. SSDlife Pro on the other hand is taking that raw value and incorrectly assuming it is total hours, so you get a silly power on hours duration!
CrystalDiskInfo seems to work out the power on hours count okay after watching the number increment over a few minutes, so you could try that if you want to see your power on hours correctly. http://crystalmark.info
I'm sure software like SSDlife will catch up shortly and start correctly converting the raw data to meaningful hours.
