Laptop GPU causes CPU to overheat

[test]

When I play rimworld on nvidia GPU, it reaches 70 degrees and CPU is 85-95 degrees. When I look at graphs I can clearly see that CPU overheats right after GPU starts heating. When I play on Intel HD, I have the same tick/second (performance) but CPU is never higher than 65-75 degrees. The fan is clean. Then laptop is very old gaming laptop, what might be the problem? In rimworld I have a workaround of playing it with Intel HD, but if I were to play games that are heavy on GPU, I won't be able to do this

most laptops use the same heatpipe/cooler for the cpu and gpu
what cpu and gpu?

most intel laptop cpus are fine to 100c before they will throttle

clean the cooler and vents in the laptop and get a cooling pad to help keep it cool

its i7 3537u and nvidia geforce 740m. CPU has 105 degree limit but I am worrying that if I continuously have it at 90 it might be bad. I thought my problem is specific since if I stress only CPU it does not overheat

90 under load is good for a gaming laptop

what if I load it for 12 hours straight, can it be bad

No, it's designed to throttle at 100, below that is not going to kill the CPU whatsoever

it is also 2 degree outside and I have window opened. I still think I have a problem, I googled most people dont get such overheating, and in summer I might have problems

-Change thermal paste
-Get a cooling pad
-Undervolt if possible

imo you have no real troubles, mr threadstarter. i would not worry until the laptop shuts down, because it would/should if the hardware of it gets to hot.

but if it shuts down that means hardware is already damaged

No, that's exactly the opposite. Most PCs have this fail-safe that prevents overheating, so they turn off upon reaching 100-110 degrees. To at least start melting solder you need 200+ degrees.

So in a nutshell, normal CPU temperature is 60 C, while 70 C is Average CPU temperature, but the maximum CPU temperature is 80 C which can cause serious problems to computer, so avoided it.

Intel Pentium II 147.2°F - 167°F 64°C - 75°C

i have been running my ryzen 5 2600 on all cores maximum with prime 95. i had no troubles running it with 95°C. then i stopped the testing, i was worrying a little and i did not need to let the testing go on. it was with stock cooling.
all in all a cpu is always protected by the mobos possibility to stop the pc from running. it is a must. that is how it mainly works imho.

This, you can't really damage computer chips from 100c, more toward the 150c mark, iirc.
Solder melts at like ~220c

So, it'll shut down long before you get to the point of damage (unless you've disabled it.)

Your CPU will slow itself down if it gets to hot, and if it can't cool down from that, it will shut down.
If you're worried about the temps, do as someone else said - Thermal paste, cooling pad, undervolt. (You could also underclock, since that would cause less power draw too, but eh, undervolting is enough.)

No, actually safer.
One constant temperature is better than one that constantly changes
Since heating and shrinking causes metals to expand and contract. Which, over time (albeit a long time) causes micro cracks in the solder/etc, which eventually stops something contacting, or adds loads of resistance (electrical), so it stops the part working.
If you leave it at the same temp, say 90, for it's entire life, it will last longer.

Though, by the point any of these parts have the effects of this ♥♥♥♥, you're going to have replaced it, because it'll be outdated.

Cap your framerate. This causes the GPU and CPU not being used at their highest capability
