Is underclock harmful to the microprocessor?

Hi Intel community:

That is the question: Is the underclock harmful or not recommendable for the microprocessor? I own an Intel Core i7 2630QM 2.0Ghz. I think that underclock is not bad for It, but I would like to know what other users and Intel support think about it. Im using an application called Throttlestop to control multiplier values.

Thank you.
