High temps after reinstalling Windows

[genexis_x]

I discovered that my laptop is running hotter under load after I've done a clean Windows install (OS build 16299.248, before that is 16299.125). While gaming, the CPU, GPU and SSD temps rise about 4℃ compared to previous temps. Even a change in ambient temperature doesn't affect the hardware temps much (a drop of ~8℃ in ambient temp only drop the hardware temps by 1-2℃). I cleaned it a while ago and there shouldn't be any dust.

 

Any explanations and solutions on this issue would be appreciated.

check the power profile.....you probably had it set to a more conservative mode before that would utilize the hardware less

What do you mean by hardware profile? I always use the same settings for my GPU (1595MHz@0.85V) and CPU (-150mv undervolt)

No offense but if in your case not even a 8°C ambient drop can be measured in hardware temps you really have no business in complaining about 4°C changed temps in my book. You debunked your own complaint.

8°C is a huge lot and although hardware should take some time to adjust to the new temps this should noticeably reduce temperatures. IF you are in a rather low temp environment your sensor could also be super innacurate  The are built for more of a 60°C-100°C range

Nice to know that. However the ambient temps are not really accurate, I just simply determine it from idle temps and weather forecast (that's why I put ~). Nevertheless, this is not that important. The real question is I still want to know why a clean Windows install causes increase in temps.

It does not. Outside temperature and in-house temperature do not change with a 1:1 ratio. 

Your room is likely hotter than it was before. Just leaving the computer on in the room increases room temperatures, albeit slowly.

The problem is, even at night where ambient temp is low, high temps still exist.

That is quite normal. If ambient temp decreases by 10, computer temp will not decrease by 10. 

 

Your laptop also most likely has target temperatures. Meaning that it tries to keep the processor at a certain temperature, and adjust fan speed accordingly. 

 

For example, my RX 580 (I know it's not a laptop part, but it makes a good example) has a target temperature of 75 C*. Under load it stays at 75 C* and adjusts fan speed to maintain it at that temperature. If the temperature could lower, the card will instead slow down the fans, meaning that it will get hotter (and remain at 75C* as a consequence).

Fan speed didn't change compared to previous ones. Once the CPU reaches its temperature limit which is 65℃, the fans start to ramp up and become audible. Again, I didn't encounter this before that. That's why it's weird.

Then maybe it could be the thermal paste. Or it is not as clean inside it as you think it is (how did you clean it?). 

 

A Windows install definitely does not raise hardware temperatures if the  usage, fan speed, ambient temperatures etc. are the same.
