under load (prime95 - blend) real temp shows me about 42 °C and the asrock utility, coretemp show me 60 °C, difference is huge smile.gif.

On PCs with multi-core processors, here is an easy way to differentiate which temperature sensors are being used by a given utility: if one CPU temperature is displayed, it is from the sensor located underneath the CPU on the motherboard PCB. If mulitple CPU temperatures are displayed, they are from the sensors located inside of the CPU itself (one for each processor core).

Both Core Temp and Real Temp display the latter temperatures and should show similar values. If that's not the case, please post a screenshot of the discrepancy with the two utilities running side by side. The most likely explanation is that they're using different TJ Max values.

I checked and compared TJ Max values between real temp and core temp and they were different,
so i set the same TJ max value i had in core temp in realtemp and now both programs are showing the same temp readings.
Thanks a lot! I never thought that it would be so simple.

Hitting the Defaults button in RealTemp should reset TJ Max to the default value. This is always a good thing to do after swapping hardware or if you have manually adjusted TJ Max in RealTemp. With Core i processors, there is no need to adjust TJ Max but some users still like to do that.

Why dont you need to adjust TJ max for i core processors on RealTemp? I have read the realtemp documantation website and there it is advised to increase the temperature accuracy rate for multiple cores.

The majority of users don't waste their time trying to calibrate their core temperature sensors. Why bother? People realize that the sensors Intel uses are not 100% accurate from idle to full load. Most users have come to accept that there is some random variation from core to core and it is no longer a big deal like it once was. If a CPU is 100% stable and it is not thermal throttling, its core temperature is unimportant.

RealTemp's calibration features were originally designed for the Core 2 CPUs.

uhmm.. so interesting. Because I think Core temperatures are major factor when overclocking in terms of not to give a harm to cpu.

Both numbers are important...... and not at all useless.

Core temp gives you the temperature internal to the CPU.....Asus is giving you temps external to the CPU..... you cooler exists external to the CPU. Your cooler only indirectly effects temps internal to the CPU. As we see especially with Haswell, the heat transfer from the cores is to the lid is very poor with many reporting 20c improvements after delidding. You could very well have an internal core temperature of 67 and a lid surface temp of 47. Your cooler is working on the 47, not the 67.

Now that's under load, but say when doing normal office stuff or wen browsing, if ya core is 45 and ya MoBo is 25 ..... what's ya fan gonna do with 23C ambient air .... not much. So if ya setting the fan profiles via BIOS, I find it gives me a better handle on where to choose my fan curve points since the cooler can only work based on the difference between the ambient air and the temps it's subject to at the CPU exterior.
