Ubuntu: Laptop fan not turning on when needed


The Question: It looks like my fan in my laptop is not turning on when appropriate. I already
removed granola (maybe it disables it far too long?)
When I put the computer in sleep mode and resume it immediately turns on the
fan (the cpu was waaaaay overheated). So the question is: why does it not turn
on when needed.
There are multiple issues here: Why, and how to diagnose this issue? How can I
control when the fan should turn on, how do I test that the code is turning on
my fan, how do I turn on the fan manually through a command if all hell breaks
lose?

It appears it may have been granola. After removing it it seems the fan does
turn on, as I hear it working at low speeds at the moment.
Will experiment more, though I can still use help finding out how to diagnose
the problem anyways just incase it was not granola and instead a random issue.
