OC on i5-4690k voltage and temp question

[Spike]

I just finished my new build the other day (in sig) and finally tried some overclocking. Last night I changed the multiplier to 44 and left voltage on auto and let the pc run AIDA64 overnight (8 hour run). After that run the CPU (according to afterburner) hit a max of 56 C on one core, the others maxed between 52 and 55. I watched my voltage (set to auto) and it varied from 1.248 to 1.252. The CPU is being cooled by a Noctua DH-14.

So, thoughts on this result? I have my ram set to use the XMP 1.3 profile so it's running at DDR3-2133 and locked to 1.5V. The temps seemed good to me so I'm tempted on just leaving it. I know people recommend locking the voltage in, but I like the ability to drop voltage in idle and the max it went seemed to be within that 1.25 people say not to go above with air cooling.

Thanks.

That's fine.. Good temps & probably the sweet spot for your setup.

Just played a few hours of BF4, hit 60 on two cores, 55 and 57 on the other two. Should I be worried? This is obviously winter but my office is pretty warm, I can only see it being a few degrees higher in the summer. Hopefully this temp at least holds, just wish it was a tad bit lower.
