High voltage, decent temps safe?

[maxh22]

Would 1.5.5V be safe if my cpu temps never exceeded 63c at Max possible load?

Is there a chance it would fry by cpu or mobo if i kept it at that voltage?

recently iv'e OCed my Phenom x4 980 to 4.4Ghz but it's only stable at 1.5.5V

The high voltage is going to shorten the lifespan of the CPU, by how much we can only guess.

It won't burn anything in my system though right?

No I do not think so but you will have to understand the risk, what are your normal load temps?

Thats why I have you

usually 50c-55c using a hyper 212 evo (the extra voltage adds onto the heat)

Those are OK temps.

Yes, you can shorten the life of a CPU by giving it more voltage, and no you can't just prevent it with an expensive CPU cooler (it might help, but it won't stop it).

This problem is "electromigration". A quick search found this link here at TH, and I'm sure you can find more authoritative sources (Intel? AMD? Wiki? scientific journals?).

Temps are just a part of the equation:

Higher voltages will increase currents through traces and gates inside the CPU which will accelerate electromigration by some amount. Keeping the CPU cool will slow the process down but cannot completely prevent it.

Since electromigration is usually a very slow process and Ivy Bridge has been on the market for little more than a month, there currently is little to no public data and anecdotal evidence about how susceptible to electromigration IB might be.
