3930k 10 degrees difference between cores

[Cosmos_i7]

I am currently overclocking my CPU and seeing what I get. So far its been stable but something that has been bothering me is the fact that "core 2" is a lot cooler than "core 0" by as much as 10 sometimes 12 degrees Celsius. Here is a CoreTemp reading:

 

 

(Ignore the power wattage, at that point it went a little strange but fixed itself moments later)

Is it an issue or should I just ignore it? I know cores tend to vary temps but that much difference? It's always in that order as well with Core 2 being the coolest and Core 0 being the warmest.

Well i wouldn't call that program accurate, considering its reporting your CPU is pulling 3465W???

 

Also you cant OC anymore with your current cooling that you are at the moment the Tcase for that chip is 66.8c and your hitting 70c so dial it back.

but yes the varying temps are normal. but always trust BIOS readings more than any software.

Tj max is 90 degrees. That's the one you need to look at not Tcase.

try using HWMonitor

My cores are often ~10C apart when using RealTemp.

try using HWMonitor

Still reports around 10 degrees difference.

So this is normal then? What would I look at then? The hottest core?

I usually take the temp for the hottest core, not sure if it's normal though

[coen113]

my core2 is much hotter than my core0,

my core2 is much hotter than my core0,

Alright then I guess its fine. Just wanted to check though.

I just bought a brand new 3930k and I'm seeing exactly the same thing.  At this particular moment I'm seeing 65,72,65,69,71,63 C for my cores while running a stress test.  Maybe it's just the sensors in this batch.  My other 3930k has about a 5C difference between the hottest and coolest cores generally.  

 

One of your cores might be right.  Maybe.  Basically pick one and go with it (be that your hottest or your coolest or somewhere in the middle).  Given how close the cores are physically to each other, they should be very similar in temperature, and 10C is not particularly similar.  I use RealTemp GT, and you can calibrate the sensors yourself to whichever core you want, if you don't like seeing the number discrepancy.

I stated I noticed that, I think it was a minor blip that I didn't notice until I posted the screenshot. Most of the time it was reporting 150w though.

Maybe it's a faulty sensor? I don't think it's anything to worry about though
