Not at all mate, aslong as it's stable than it does nothing at all to your CPU - infact it lowers heat and may even lengthen the life span of your chip.
What I would do though is make sure the CPU goes through a good stress test to make sure it really is dead stable, the last thing you want is an unstable system.
Prime95 will be a good place to start, with atleast a 12 hour test and I find gaming can give the CPU a good stretch aswell, I've had games crash my system when P95 couldn't before.
If it passes through all that, then you're all good
