Core i3 Temps

[NightSt@lk3r]

Is it normal for 1 core to be 5-7c hotter than the other all the time?

at idle Core 1 is at around 30-32c and core 2 is at 37-40c

under load Core 1 reaches around 60c and Core 2 65c or so?

It's fine.

 

[Mak3R]

Tis fine, on idle mine range between 22-30

 

[RJC]

Yep, your fine

The heat spreader might be not be completely flat.

What is more likely is that there are background applications that are using resources. These background applications are normally shunted between the cores, the nett result is one core tends to be doing a touch more work (and therefore hotter) than the others.

Short answer yep all good.

Ok cheers guys, was thinking about reseating cpu cooler but i wont bother now, at least not till i put the motherboard into the new case.

It's same on i7, core 0 and 2 tend to idle 5c or so higher than 1 and 3 do, probably just how the cores are physically arranged or something.

Is it necessary to adjust offsets (ie -5) with i3 CPU's ? My idle is 27-30 with CoreTemp yet the BIOS says its 22-24.

My i3 (with stock cooler and clocked @ 3.9Ghz) is idling 34/30...

Very common, i was actually pleasantly surprised that my 920 @ 4.2Ghz idles and loads with a max variance of only 2C between cores under ibt.

In bios there are no back ground applications or services running, Windows (operating system) obviously is not loaded yet. So you will always find a small difference between tempretures when in BIOS versus when the CPU is doing some work, and it is always doing some work, regardless how small that amount is when booted to the OS.

All temperature applications use the same sensors that the BIOS does to read temps. It is just the way that the sensors is interpreted or represented that is application or BIOS version dependant - but that is a whole different issue.

Hope that clears up your puzzle.

The BIOS actually loads the cpu somewhat, also lots of optimisations for cpu idle states etc.. that are built into operating systems ... are not present in the BIOS, if you watch a cpu temp in the BIOS it does climb up. Also most BIOSes i know read the cpu temp from a diode onboard the board itself and not the DTS sensors in the cpu that core temp, realtemp etc.. use, hence the lower BIOS temp reading as its reading an external and not internal core temp. Haven't seen a bios that has displayed more than a single reading for cpu temp, they don't display cores individually as the reading is from a completely different sensor.
