Screwy Opty 165 Temp readings

[DudeAbides]

Hi- Is it possible that the temp sensor on one of my cores is defective? I'm currently running at 2.7 with 1.42 voltage, and the heat difference between the two is just stupid. The cold core runs 26/41 idle/load, and the hot one runs 36/75(!) idle/load (all temps in c). I'm using Core Temp to measure temps and Orthos to load both cores. Which reminds me- the temp jumps from ~40 to 75 on the hot core almost instantly after I start Orthos. I've tried lapping my heatsink and even removing the IHS, but it didn't help. (It did drop overall temps, but didn't help even the difference between the cores.)

Is it possible for two cores in the same processor to run with a 30c difference between them? Wouldn't the one core bust when it got up that high? Or is it more likely that the temp sensor on the second core is just wrong?

Thanks for the help!

Having spent the last 18 months glancing at the core % usage differences on my G15 LCD and seeing that one of the cores is hardly ever used, it would not surprise me that a busy core would run hotter - espec if overclocked.

If you are multi-running apps, how about manually assigning core affinity to apps with a view to balance core usage?

I don't overclock, 'cos I can't afford to deliberately destroy components - but perhaps 75C indicates that you are in the upper limits?

Tbh it just sounds like core temp is reading it wrong too me.

core temp show a disparity of between 3 and 6 degrees for me.
