one cpu core is constantly thermal throttling

[Host Migration]

i have a laptop with an i7-7700hq
out of the 4 cores (0-3) core one is always thermal throttling

in throttle stop the max temps for the cores have been as follows

core: 0
81
81
core: 1
85
85
core: 2
79
79
core: 3
78
78

i dont understand pls help

im idling around 50c btw

How do you know it's throttling?

You could ask here^. Just a suggestion.

That's just how CPUs work. They have a thermal budget for the whole package and depending on the load and cooling, they can up- or downclock certain cores.

Ignore those applications.

They are wrong, your CPU isn't throttling.

It might not be boosting 100% but that is it. This is perfectly normal for laptops.

[wuddih]

can be just a crappy chip or misapplied thermalpads ... and since that is a laptop chip ... you are probably stuck with it, that is not a warranty issue.

Tj max of that chip is 100c, id imagine it would first get to 100c then start to throttle because of temps. 85c is warm but nothing to be alarmed about.

XTU and Throttlestop (never herd of that one) is probably worng.

What you can do is play a game in windowed mode open task manger and on the cpu graph, watch the core speeds when you play, they should bounce around the base clock (2.8ghz) and turbo speeds (3.8ghz).

Idling at you're desktop the cpu will downclock, thats normal.

You can do this with other software like core temp or hwmonitor, or you can download the trial version of adia64 and stress the cpu and it will tell you if its throttling.

I personally use Core Temp software and have it run in the background and set a max temp of 90c on my 5960x, of it ever hits that temp, it will put my computer to sleep, i did that just in case im at work and my water cooler quits working.

the thermal limit is set to 85c, laptop manufacturers are able to set the thermal throttling (prochot) to anything between 100-85, mines set to 85

dont stress test it your gonna shorten the life of you cpu

[Cathulhu]

Seems you throttled your CPU a bit too much when it takes you so long to answer a thread from 2018.

I don't particularly know what happened after this post, I believe I re-pasted it (Which helped slightly) and played less demanding games until I built my own desktop about a year later.

How much do you figure stress testing will shorten the life of a CPU? Are we talking fractions of a second? Or years? Or just some ill defined nebulous amount of time that can't be quantified, but you're sure it'll be shorter than if you never turned the CPU on at all?

Don't forget to show your work.

Generally most programs only need 1 thread. In the past, which indeed still is with the 7th gen, cpus would always assign the same processing core to the same thread.
so one specific core would therefore be used 'mostly', thus seeing a termperature difference on the main core isn't really that uncommon. In your case it happens to be the processing core at index 1. (this core may also perform dualthreading (hyperthreading)

However, seeing your temperatures go to 80 is a bit concerning. You may want to use a more powerful cooler.
There isn't much problems with 80, but I doubt you are a datacenter and temperatures that high will affect the processing speed.

Modern Intel CPUs (12th gen and such) have efficiency cores and a buildin mechanic to distribute the tasks, and may not use the same core mostly as such. This tech is relatively new.

Anyway, try properly cooling your CPU next time I guess. Modern Stock coolers are pretty good, but if you know you'll be doing demanding stuff you may want to opt for a bigger cooler.

Unfortunately the i7-7700hq was a laptop cpu, the internal cooling for the CPU was woefully inadequate for the CPU let alone the GPU which was also being cooled by the same cooling pipe.

I now run a water cooled R5 5600x which is currently sitting at 32c idle
