Cooler Master Hyper 212 EVO CPU Cooler (RR-212E-20PK-R1)
Reviewed by AlDyer

All in all great cooler for the money and has always worked reliably. Excellent for a backup cooling system or for low-cost budget computers, while still being able to overclock.

So I tried overclocking to 4.7 GHz at vcore 1.365...
RIght now it is stable (I just started running Prime95) and temps are below 70 degrees Celsius which is good.
What isn't good is my vcore is going past 1.4 (like max is 1.41) is that okay?
Is that safe and normal?
Thanks guys

.

EDIT:
Actually ROG CPU-Z says max is like 1.38
but CoreTemp says "VID" is 1.4... I thought that was vcore. What is that lolz?

Oh yeah, that is very safe. If I recall, then I think the maximum safe is around 1.55V. Some people will say 1.52V, but I remember seeing people on here exceeding 1.52V with no problems (except for a little more heat).

I think the VID is the voltage that the CPU should pull from the motherboard when the voltage is set to Auto.

Oh thanks.
Just a question:
-Say my vcore was set to like 1.4v... how long do you think my CPU would last?

I don't know, but probably a long time. It would last even longer if you were using an Offset Voltage because then it wouldn't be sitting at 1.4V "24/7". Instead, the voltage would adjust as needed which means that when it's idling, the voltage would be extremely low.

How do you do that?

When you applied the thermal paste, did you fill the gaps between the pipes first? If not, then this may be why.

2. No I don't think so. Can I fix this by just taking it off?

You should be able to. These gaps need to be filled evenly like this:

In a little while, I can post instructions on setting an Offset Voltage. :)
