Intel 3570k High temp on second core - Page 2

post #11 of 21
My 3570k does this as well. It seems pretty common. My Core0 temperature sensor reads a few degrees low (sometimes min temperatures below ambient, impossible!) and Core1 is usually hotter than the others. Core 2 is usually close to Core1, but a few degrees cooler, and Core 3 is the most "normal" of the lot. The layout on the die mirrors the order in RealTemp and explains the temperature variation somewhat. Core0 is on the outside, Core1 and 2 are sandwiched in the middle and run hot as a result, and Core3 is almost at the edge of the die, and pretty cool as a result.

The net result is that there is typically about an 8 deg. C difference from Core0 (cool) to Core1 (hottest). I gave up worrying about it-- I have proven to myself that it works fine as long as the max temps on the hottest core stay below 98c.

Thanks for that. Plus Rep

Seems 417

the case is similar to mine. Its most likely normal. Odd how the 2nd core is hotter in our Ivy chips.

My Q6600 has this issue too.
The third core is usually 7-8 C higher than the rest. But in 4 years and many stress tests, nothing bad happened.
So enjoy your build:)

Thanks a lot for the confirmation guys, I was about to re-apply the thermal paste yet again, but it seems there is no point. biggrin.gif

I think you might as well try for a good reseat of the cooler with a small amount of TIM with it. You might just lower the temps slightly.

Many if not most Intel CPUs have widely varying core temps. Its mainly due to the inaccuracy of the temp diodes, esp at normal or idle temps. These temps are not important for intel. What is important is the TjMax and the readings get more accurate as the temps rise and get near those. TjMax is what Intel cares about and its where the CPU throttles or shuts down to protect itself.

My 2nd core is 5-8c hotter than the other 3 cores. I will post my pictures tonight. I also slightly moved my CM Hyper 212+ after installation. I will re-seat it and let you know if it helps at all.

I am having the same problem - Core 2 (2nd Core, maybe technically Core 1 is three is a Core 0) is 7-9 deg C higher than Core 1/0 (first core).

Did anyone who was having the same problem resolve it by re applying/reseating their cooler, or did they end up with the same issue?

I have been stress testing my build for about an hour today (after adding some thermal paste.) I was posting temps that I was not comfortable with, and this seemed to have evened it out. Though, I have to say that I am not seeing the same temperature readings any of you are. Here are my idle and stress tested cpu temps now, after the thermal paste. I am wanting to maybe overclock it to 4.2, but when I got there last night I was posting dangerous temps; even without upping the voltage.



It seems I am having a pretty even heat across the chip. Yea the 2nd and 3rd cores are warmer, but they are similar in temperature throughout. It also seems like my 4th core is running slightly hotter than the first core, but not as hot as the 2nd and 3rd cores during stress testing, but when idle the 4th core is the hottest of them all. Interesting if the 4th and 3rd run hotter on mine and don't reflect the assessment that they are located closer to the edge. Is this true?
