High termals after reassembly lg g7

[Boldrino]

Hi everyone,

I just replaced my lg g7 display and frame(heatpipe included), added thermal paste(MX-4) and reasslembled all but back panel, because i wanted to make sure everything was working fine. Everything is actually working fine but the cpu temp when testing with "CPU Throttling test", where i see one core going up to 82° and the others beetween 70 and 80 degrees. I disassebled it once again to clean the thermal paste and re-apply it again(even so it looked well spreaded to me) and the temperature still is the same running the same test.
I thought that maybe temperature reading from the app wasn't accurate so I checked at the same time with "DevCheck" overlayed, yet this one shows temperatures even higher like 86° top.

Can anyone run the app "CPU Throttling test" and share the max temperature reached?
I doesn't need to run for like 5 minutes like it says in the app, 30 seconds was all it tooked for me to reach that 82° on the hottest core.

In my opinion, the heat pipe is damaged. My G7 is a second hand model that came with a non-fictional heat pipe. Saw that when I took it apart to change the display.

You could search for a replacement heat pipe on some online shopping websites, but do make sure they are functional units. I have seen some sellers selling harvested g7 heatpipes and they are definitely not harvested correctly. They likely cracked the heatpipe.

To test a heatpipe, immerse one end of it in warm water, you should feel the heat on the other end in a couple seconds. If you don't feel the heat, then it's quite likely the heatpipe is damaged.

Protip: You can measure the dimensions of the stock heatpipe and get a generic one with similar dimensions, it's not mandatory to get a g7 heatpipe.

Well, you could be right...
But I must say that I made several runs to check temps, and after doing one of 15 minutes the highest temp recorded was not so far off, 85°C to be exact and it seems like it's still running cooler that other smartphone with snapdragon 845(like op6, poco f1) because those do something up in the 90°C.
Don't know if I should just relax or be worried about it.
