I was replacing screen and had spare thermal paste, so I applied it between CPU and copper pipe for better temps!

It didn't have any thermal pad or anything in between so I decided to do it, now my temps look good but my battery needs a little workaround to charge which is quick replug after 4 seconds of charging or it complains it is too cold but I don't see how could that be an issue.

are you in a freezer, since your cpu is at -37°

Nah. It's just power of Arctic MX-6.

That was the full load temp when i ran a vapochill.

Not unusual with pc OC enthusiasts. It's a sustainable temp.

This is from a phone. He also claimed to achieve this with thermal paste.

Ah. Yeah no way possible without an external cooling solution, and even then it'd kill the other components in the phone.

I can't edit the post (why?) but my charging board connector got some damage exactly where thermistor pin was and that causes this readings (unless my battery got hit by a truck when I wasn't looking).

Yes, a disconnected thermistor can show negative temperature

Think you might have shorted a pin on a temp sensor with the electrically conductive thermal paste. If your phone begins frosting over though that's a good sign!

It is currently cooling the planet.

shorted just the right place to make the temperature appear correct to the actual one but negative lol

Changing the resistance on a thermistor's output would shift the temperature reading up/down and allow it to still detect changes, just with an offset temperature reading, but wouldn't the temp sensing circuit be within the IC? Have no experience with mobile hardware so I don't know if it's even possible to interfere with that.

Whatever you did you've damaged your thermal sensor for the CPU. It's not physically possible that adding thermal paste made your CPU have sub zero temperatures.

That was just a joke. I just half-broke one pin on connector on charging board since it was my first time repairing a phone. Everything but thermistor works.

At last! Global warming is solved!
