Is it normal for 13th gen to have big variance of up to 8c between each package in performance cores?
yup. up to 10c variance is pretty normal. however if its more than 15c variance its probably a mounting issue.
Just out of curiosity is it core 5 and 7 that are higher?
It’s a 13600K, core 4 and 6 are the ones that usually are higher.
Oh ok are 4 and 6 your favoured cores? I just say because I had a 13700k and core 5 and 7 were allways hotter. Then I got a 14900k and same again 5 and 7 hotter both by like 7c or so . But what I noticed is core 5 and 7 are the two favored cores on both my cpus. And even in multi core workloads those two allways get hotter. I think because they are the favourites they get work sent to them first and don’t get as much of a break.
Not sure if there is a way you can disable favoured cores I haven’t really looked into it yet.
Yes.
Thanks! Just variance in IHS / cooler contact then I guess. Do you happen to know if there’s any way to get more even temps?
If reapplying thermal paste and verifying the heatsink pushes down on the IHS evenly doesn’t help then I suppose what might help is a delid, clean the die, grind down the IHS sides (to reduce the gap between the die and the IHS), apply liquid metal and reseat the IHS
Have you delidded your CPU?
Having done multiple re-seatings and pastes I can confirm that it is currently as good as it will get. The paste spread is near perfect, which is why I am a bit confused here. It’s the same cores regardless of cooler used.
Delidding is a bit outside my comfort zone, and I’m not sure if it’s worth the risk for my use case. Not sure yet how heavy the CPU will be stressed during music / audio projects just yet, but I have a feeling it will get close to 100% by the end stage of big projects.
not yet, maybe in 3 years :)
