Are these temps OK?

[Davidthewin]

i5 3570k running on a Gigabyte GA-Z77x-UD3H with a H100i with SP120s in push at 1600RPM.

It's running at 40 multiplier at 1.1V in the BIOS with LLC on extreme. I haven't overclocked before so I watched TTLs 1155 guide. I managed to get stock clocks stable at 1.05V (stock volts are 1.12) and after 30 minutes of the test below, 4GHz seemed stable at 1.1V.

Sorry for the resolution, but the important part is that one of my cores is touching 72C whilst one is sitting cool under 60C. Is this normal? Should I push it further?

On an unrelated note, I'm pretty sure Link is bugging out with my H100i coolant temps, because on a 60C+ CPU I very much doubt the coolant is 32C. Also I have no idea what is up with the "VBAT" reading on OCCT.

Did a quick prime test and got

Also ran OCCT with RealTemp to check that OCCT was checking the temps correctly and they agreed with each other

Coolant temp looks good for that CPU temp

Really? I figured it would be close to the CPU temp?

VBAT is/was CMOS Battery Voltage. since most use a 3.0v battery, the voltage
point in 99% of systems is off. most read 3.2-3.6v on a 3v battery..
not really a concern.

as for the temperature, for that low speed 1500rpm, thats a fine temp.

Crappy cement like grease inside the Ivy Bridge CPU's is to blame here. Delid if you are comfortable doing so. Personally I'm not and it's a shame as my 3770k seems to be a great piece of silicon just has that crap grease on it which sends my temps haywire.

nope, in any cooling system the cooler has to be a lower temperature than the thing being cooled, otherwise no energy transfer would take place (no cooling).

typically a good water cooling system coolant will only be a couple of degrees above ambient temperature

as for the one core being hotter than the others, as far as i can make out that's just "welcome to ivybridge" its not a big issue but if you are going to push the overclock then you would benefit from delidding it and applying some better tim between the die and the ihs or even running it naked.
Its a risky job but thats really the only way to fix the temperature issue so i would just live with it unless going for a custom water cooling loop

you could certainly push the overclock a lot further if it were me i would aim for 80c max in prime which in the real world under a realistic load would be well within happy cpu limits.

you should easily manage 4.3-4.4ghz if you want to i would guess

Alright thanks, I figured the coolant temps would be at least a little higher than that but I don't think I'm going to go as far as delidding it.
