i5 6600k core0 to core3 temp difference

[d0gma14]

Under load my core 0 and core 3 temps differ by 6-9 Celsius. Before I redo the paste, is this normal to Skylake or just a bad thermal paste spread? TIA!

Completely normal.

One or more cores may have a higher reading simply because they are more heavily loaded or the only ones being used.

Thanks for the response.

To satisfy my own curiosity and put my mind at ease for the next 5 years (next build). I went ahead and redid the thermal paste.
Upon removing the cooler, one side did have better coverage. So I redid the paste, reconnected, and no change to the temperatures, they still have a 6-9 differential. I have no intention on redoing the internal CPU paste, so I guess it will be something I live with.

Your temps are normal. I run my CPU at close to 100 almost daily, starting 4 years ago. I can run it up to 110, that's when it'll shut down to prevent damage. It throttles at 100, you really have nothing to worry about. Even if you overclock the CPU, its still going to last for 10 years...

You run your CPU at almost 100c? Don't tell people to do that, if you want to ruin your CPU, go for it, but don't make others do the same through bad advice.

I'm running a 6700k so your settings may vary slightly but Something to do on your skylake would be to go into your bios and set voltage to manual pop in something like 1.22v on the vcore then save and reboot. Download and run aida64 stability test for like 10-30 minuyes and if you're stable go back into bios and set the vcore to adaptive then save again and reboot. This will lower your temps since most stock auto setting overvolt the piss out of the skylake cpu's causing extra heat. Mine was volting my stock settings to 1.44v which is insane! I found it to be stable at 1.2volts then set it to adaptive to account for the turbo boost and now i never go over 56c. I was at 70c when i first put it together like your cpu is. Everything else looks normal.

Also yes do not run your cpu over 90c max for any length of time. The cpu's tdp is like 105c so the farther away from that you can get the better. Making it seem like its ok to run at 100c regularly is bad advice. It throttles there because its at its temp limit. You never want to run close to to temp limit.

 

[Suzuki@1473780084@1473780163]

The throttle temp isn't the limit, that's misinformation. You can't harm a CPU unless you overvoltage straight from BIOS ensuring you wont even reach BIOS without resetting cmos. It's not bad advice at all. I'm not telling OP to aim for 100C. I'm saying that you can't damage a CPU just because the temperature is high, it shutdown to prevent damage, it doesn't shut down because its damaged. As long as a CPU is able to throttle, you can't damage it, so don't say otherwise. Downside is that you won't reach it's max potential, that's it.

 

[azzazel_99]

Wait did you just say you cant harm a cpu unless you over volt it? So heat doesn't hard cpu's at all? Really? Cpu's lifespan is SEVERELY cut short the hotter it runs and the closer it runs to its max temp. The cooler you can keep it the better. the skylake cpu's using a cooler as simple as the hyper 212 evo from cooler master with 2 fans on it like i have works great and even better once you get your voltages as low as you can and be stable. The cooler you can keep your computer parts the better they work and the longer they'll last. HEAT WILL damage a cpu regardless if you're running low or high voltage. Temp gets up there and you risk your new cpu.

 

[Suzuki@1473780084@1473780163]

No, it won't matter how much lifespan is affected. If you run it at 90C rendering or whatnot for the most of the days, then it's going to last way longer and you would of already bought a new CPU, because current one is too slow.

 

[DJDeCiBeL]

To the OP, you have nothing to worry about. As has been said, it's normal, and expected.

As for the last half of this thread, besides overvolting, heat is the main killer of any electrical appliance, be it a CPU or whatever else. Despite what Suzuki would have you believe, you ARE shortening the lifespan of a component by running it hot consistently. Will there be some components that outlive their usefulness, even if you run them hot (way hotter than recommended)? Yes, but why take the risk with a CPU when decent cooling is so inexpensive?

Thanks for the info. My goal was to get even temperatures across all cores (i.e. 60-59-60-59). In my past experience if the core differential was this far apart either the cooler was not seated properly or the thermal paste was not applied correctly. During my research I've found both situations for the i5 6600k. Some people have posted pics of core temps of 65-66-64-65 and others like mine 67-68-60-59.

 

[azzazel_99]

yea mine are random like that too.

Running Prime95 with my 4.4 ghz OC, I'm showing 68, 66, 64, and 59. I have a bigger spread than you.
