looks fine, why not cm hyper 212+?

quite fine for such frequency & vCore. 
as for me i would start to worry when the temp goes up to 90C.
avoid stressing the 2600K 5GHz HT @ 1.54v + as this might cause chip degradation.

I believe that's according to Intel's limit.!
If ppl follow this spec then better dont OC it. But thete must be a reason why Intel releases K series. If not for OC then what is it for?

Like mentioned earlier, degradation MIGHT only occur if u stress the CPU at 5GHz + HT at 1.54v+ for long hour so if u didnt play at this condition i dont see why u should worry.

its for OC, but is limited becoz of 'heat'

Strange still quite new to this OC offset mode as I wanna my SB temp to be low while idle.

CPU = i5, 2500K, P67 Sabertooth

OC by using turbo per core

1 Active core multi = 43(4.3GHz)
2 Active cores multi = 41
3 Active cores multi = 39
4 Active cores multi = 38 

everything else Auto,
Internal PLL = Disabled since I low OC only.
Vcore phase control = Optimized
LLC = Regular <-- if I set medium I cannot boot window at all.

CPU Vcore = Offset (-0.015) because while on load I get higher vcore than stock even in 3.8GHz. So it is logical to set offset -negative. But Using offset voltage seems got both side effect, if u go positive or neutral = u get much HIGH vcore on LOAD which is not necessary, then if u go -negative offset the idle voltage go simply too low,

once I set -0.025 b4, my idle vcore go below like 0.888 @ CPU-Z *I was able to play games for whole day, but during my working time which my cpu idle, it crash. So the problem is still the idle side voltage, but if I set neutral/positive offset my vcore during load when much higher than what is needed than manual. Any idea to tighten the auto voltage range? higher on idle, lower on load?

Anyone here got good example of setting for offset OCing?
