Temperature question CPU

Well, I'm not familiar with the HWinfo64 software, so I'm not sure what I was looking at in the first pic.
The second pic clearly shows the core temps and they are all excellent.
Is there a help file for that software to tell you what temp 2 and 5 are? I no longer believe that they are CPU core temps. I think they are from other sensors on the system. They could be anything from voltage regulators to GPU sensors.
In any case don't worry about the CPU. But see if you can find out anything about where those other sensors are.

No, I don't believe that two of the four cores would have temperatures significantly higher than the others.
It may be possible that the OS is assigning those cores (affinity) to some heavy CPU processes.
It could be that the CPU cooler is more effective over one area than another (poor thermal paste application?)
Or it could be an error in the sensor reading, or in the software that displays it (although less likely)

The temperatures are less than the thermal limits for just about every chip that I know of, so I wouldn't panic. But if it were my rig, I would start looking for a better cooling solution, even if it is just cleaning and re-applying the paste.

Hmmm, could well be that I've placed the cooler one side tighter than the other. Or maybe it's my thermal pasting application.

Any idea why this has different temps?

Took both screen shots within a few seconds of each other. I don't understand the difference between 'temp 1' and then the Core temps.

Well I feel a little more reassured, I'll try to figure out what those sensors are.

Thanks very much :)

So I tried out realtemp and there is a similar temperature being displayed for 'distance to TJ Max' (in the 70's)

Maybe that is what HWiNFO is displaying?

That makes sense.
I found a couple of quick quotes via google, In any event, I don't think you have anything to worry about:

Tj max stands for Tjunction Max, Tjunction is another word for core temps. All Intel Core processors have a Tj max with values that vary greatly, notebook processor Tj max values are known as they are provided from Intel. Desktop processors on the other hand are not documented and we can do nothing but guess.

Tj max is the maximum allowable temp for a processor's internal cores, if you reach Tj max the processor's THERMTRIP# signal will activate shutdown to prevent damage to the processor.

The TJ register is a countdown value. When it hits zero, the CPU will shutdown. However, Intel does not provide what the zero value's actual temperature for desktop parts. This TJ Max value varies between processors and steppings. Most application only assume the TJ Max temperature and therefore are not accurate.
