6700k idle temps?

Heya, i recently build my new skylake system and while everything seems to be working fine, there is something weird with idle temp:

With an ambient temp of around 24-25c, it is impossible to have the cores running below that and even less with an air cooling, as thats what i use, noctua d14.

Only the cpu package shows what i believe would be the correct idle temp, so, do i have a faulty dts sensors?
I know that idle are not that important overall, but i wonder if this can affect the load temps not begin read correctly too...

I got this 6700k to 4.5 and after 2 hours of x264 testing, load temps peak at around 66-72c...
 
To begin with, the sensors are calibrated towards tjmax. So accuracy at idle is going to be lower. They are usually not that far off tho.

Have you tried another tool, just in case? Like CPUID HWMonitor.
 
I wouldn't worry much about it. One of my cores hit 27C in idle. While ambient case is 28C and ambient outside is 25.8C. As said, they are calibrated against tjmax and nothing else.
 
But almost 10c off seems quite alot, i wonder if load temps are also affected by this and are showing 72c when they should be 80c?
Don't know if return to store...
 
You can ask Intel if you worry. Load temperatures shouldn't be off. Accuracy should increase towards 100C.
 
Shintai is very correct.. Uncalibrated DTS is not so uncommon, they are designed as a "Trigger" calibrated only at TJmax which it's the throttle point, so as he said the closer to TjunctionMax the more accurate temp are gona be, I also had a 3770K with uncalibrated DTS (digital thermal sensor) and that chip can have idle spikes on all cores of exactly 5C below real temperature (measured with a thermal probe in the core die), so nothing to worry exactly.. coincidentally in the binning process to find a good 3770K overclocker that one with the faulty DTS was the best..
