i5 2500k big difference in cpu and core temp.. normal?

[idata]

hi, I recently bought a core i5 2500k cpu with corsair hydro h80 water cooling. according to aida64 my idle temp is 19-20ºC / 66/68ºF but the core temp is 29-31ºC/84-86ºF.

We will need to put attention on the Temperature for the Processor. For this specific Temperature, the maximum normal Temperature is 66.8 °C.

Most of the monitoring tools are reporting core Temperature. For sure, this information will be higher than the Temperature reported for the whole CPU.

i wanna know if this is normal. you are telling me in this case the maximum normal temp is 66.8ºc not 72.6 . then my temperature is not normal?

i dont think this difference is normal for most users, but i need the opinion for an expert. Maybe it's a problem with the thermal paste? im using a water cooling. thanks
