i think there is something wrong with my temperature sensor

varun988

i had heating issues and i serviced my laptop and the heating issue was fixed !! but other problem arises i.e. predator sense application showing wrong temperature. you may ask how i am sure abt that...i to touched my laptop at the areas where we can sense the heat and i didnt even get heated ,but  it shows 98 or 85 lke that !!!
i checked with other application and it showed the same !!!
i contacted  the service center and they didnt know the solution for this !!!! any one knows the solution for this ???
my laptop model is predator helios G3-572 1050ti 
because of wrong temperature readings ....my fps gets shuttered !!! and affects my performance !!!

Where did you touch? G3-572 tends to get hot in the area north of function keys (F1-F12).

Yup it's basically the left and top left of keyboard as the fans are in the right side (looking at the laptop open) the cooling pipes extend to the left side and that's the major heating zone

i touched the same spot as all of u said and noticed not that heat!!!!

The sensors are usually right i haven't seen a faulty temp sensor as the sensors are built into the CPU/GPU and i don't see a way of a sensor being faulty if you are having fps drop issues means the sensors are giving the correct temps and you have cpu/gpu thermal throttling all points to it and the temps you posted above thermal throttling will start after 90 and up for cpu and it will reduce performance drastically and fps will drop a lot you can optimize windows and even send it back for repaste if needed also there are other ways to drop temps which officially not supported by any manufacturer it's own user's risk you are welcome to join the predator group on FB and follow @Red-Sand (Hotel Hero) youtube channel to improve you temps

Try playing hard for a while and then you'll see that area warmer, if not hot.

CPU and GPU die temperatures fluctuate at a MUCH faster temperature than you realize. In a matter of seconds (some cases less) you can see a 20-30C jump in temperatures within the CPU die depending on load. This is not something you will "feel" with your hand anywhere on the laptop. It is WITHIN the CPU die. This is the temperature that ultimately determines whether you begin throttling under load.

It sounds like you have re-pasted and are now noticing sudden spikes in temperature under load across various cores. This is indicative of an unsuccessful repaste! Perhaps not enough thermal paste was used, the heatsink was misaligned, etc. If you are regularly seeing spikes of 98C on some cores as you mention, I would attempt the repaste again and verify it's all correct.

repaste was done at acer sevice center!!!

whAT IM trying to say is my laptop shows temperture like 85 -98c but when i touch the areas,it feels like it should or it is like 45-60c
and these things happens most of the time when i opened a game or opened a heavy load application

Temps you see are CPU and GPU temps. The places you touch are exterior areas and not CPU/GPU directly; hence the difference.
