E8400 temp weirdness

[Snafu]

My core temps are reading significantly different values and wondered if anyone has a similar experience and hopefully a fix. I am dying for a fix because I don't feel comfortable overclocking this system until I know what are the real temps.

My system is basically:

* Intel E8400

* Gigabyte EP35-DS3P

* OCZ PC2-9200 Reapers

* Seagate 3GB/s HDD

The cpu is water cooled with 120x240 and 120x120 rads.

I flashed to the latest bios (F6a) and found that the temperatures (per Speed Fan) were pretty much the same – still out of whack. This was confirmed with Real Temp.

I tried the calibration approach used for Real Temp by dropping the core speed to 1.6GHz (6x266) and core voltage to 1.10v. The temp readings were 46/20 at idle (water cooled and RT at 18C).

Reset the core speed to normal 3.0GHz (9x333) and core voltage set to “normal”. Idle temps were the same (45/20) as the core running at 1.6GHz. The load temps were 51/33 as seen in Real Temp after running Orthos.

So the bios update did not fix the temperature readings and trying to recalibrate Real Temp won’t work.

Anyone run into similar out of whack readings and heard of a fix?

Thanks

Maybe your motherboard temp reader is damaged?

I thought (right or wrong) the core sensors are on the core itself and not on the board.

I have read about stuck sensors but it seems recalibrating real temp solved the problem. In this case however, it does not seem to matter what the core speed is and the same readings are given.

EDIT: anyone seen a naked e8400 (without the heat shield)?

I ran Real Temp's cooldown test. Here are the results:

im running a e8400 on an Asus P5Q-e and ive never really noticed any irregular temperatures must be something to do with the mobo. mine is sitting at stock speed with a freezer pro 7 and it idels at about 31-33oC hope this helps

I've had similar results on my quad, was just a simple case of removing and re-installing the cooler. I don't think it was perfectly flat last time, even tightening of the screws did it though.

check and see if theres plenty of heat paste under there so theres a good connection as well. cpu hotspots arent cool my mate killed a q6600 clocked at 3.4 cause of that bad times my friends bad times.

Try using HWMonitor to monitor the temps.

Thanks for the replies! I have confirmed that there is good contact with the IHS.

I spoke with unclewebb (author of Real Temp I believe) and so far the conclusion is that the sensors are not stuck (at least at this level). I have recalibrated Real Temp and so far the results are better.

The system idles at 23C (6x333, water cooled with RT @18C). More on what is happening with the sensors might be gleaned after pushing this e8400 higher (and hotter).

I'll keep you posted on how the overclock goes and temps.
