E8200 temp difference between cores

My E8200 was having some really weird temps, they were apart like 10+ degrees. So I reapplied (and its on totally perfect now) the thermal compound (MX2) on the cpu and now it's only slightly changed.

It's like this:

Core 1: Min 43 / Max 65
Core 2: Min 50 / Max 70

How can this difference still be so big? I'm using the stock intel cooler. Is the temp sensor of 1 core just borked or?

Are you using CoreTemp?
 
That difference is core temps is OK. Usually if you can keep the temp delta under high single digits, everything is setup correctly as far as the cooling is concerned.
 
Its likely that one sensor is either stuck or is badly calibrated for lower temps.
The temp sensors are only calibrated to give the correct temperature when the CPU reaches throttling temperature.
Any other temps are not guaranteed to be read correctly.

ps use Realtemp to measure temps of E8x00 series chips.
It was written to compensate for some of the temperature reading problems.
 
Ok.... using Realtemp:

Core 1: Min 33 / Max 57
Core 2: Min 38 / Max 60


It's way way lower.... makes me a happy man though if these are the correct temps :p
 
The temps are about 10c lower but so is Tj max, so it makes no difference to how far you can go, it just looks better.
The chap (UncleWeb) who wrote Realtemp used a heat sensor to determine that the reported results from other temp readers are 10C too high and sometimes dont follow a straightforward linear law so made Realtemp to help correct them.
 
Xeanor: I have the same thing going on with my E8200. CoreTemp's numbers are 10C higher, but the Tj max is also 10C higher.

What's up with these high temps? My E6550 was around 28 on CoreTemp. I upgrade to the E8200, which is supposed to be even better on conserving energy, and it's 20 freaking degrees hotter?! What am I missing? Was CoreTemp being retarded when measuring the E6550?
 
Use Realtemp to get closest to the correct temps.

The same thing happened to me when I bought an E8400. CoreTemp was reporting temperatures that were WAY too high and my Fluke 62 IR thermometer proved it. When the Fluke was showing 35C, CoreTemp was reporting 50C so don't believe everything you see.

When uncalibrated, the idle temperatures from ALL Intel core based chips are not very accurate. The sensor was not designed or calibrated to work 100% accurately at idle so comparing idle temps from one processor to the next is pointless. You're comparing apples and oranges. They're both round but that's about it. The CoreTemp reported numbers at idle for your E6550 are meaningless and really meaningless for your E8200.
