CPU Temps and Sensor Locations

[Adomis63]

So a while back my HP pavillion laptop with an AMD A6 APU has been randomly shutting down, the fans hike up and then blip, its off. So I looked at the temps to find that the "CPU 0 Package" temperature in hwinfo (and a few other programs as well) is always 70*c+! In hwinfo theres two sensors listed, "cpu 0" and "cpu 0 package" - and I'm thinking the package sensor is bad, because the cpu 0 sensor is always in an acceptable range. I've tried to *fix* the cooling system with copper shims and cleaning everything out with no effect at all. The one sensor always indicates temps 70-120*c.

 

I guess my question here is can I replace the "cpu 0 package" sensor by replacing the CPU or is that a sensor that is on the motherboard?

By "cleaning everything" out do you mean replacing the thermal paste and remounting your cooler and removing all the dust?

[Adomis63]

Yes. The cooler is clean of all dust, and the heat pipe even still works! I only experimented with the copper shims to eliminate any gap if there was one. Those also had a little thermal paste on them.

Use AMD Overdrive, but it measures the temp in thermal margin, so lower is better

(Overdrive is the best tool for monitoring AMD CPUs/APUs)

What thermal paste did you use when you put it back together?

Hey! Welcome to the forum. Hope you fill in your bio and enjoy our company! 

If you're replying to a specific person and expect a reply from them, use the quote button locad under each post. That way they get a notification. Otherwise it's pretty much luck of the draw if they wonder back in this topic to see what you're saying. Secondly, it's customary to put large images inside a spoiler (the eye icon in the edit view). A lot of us are on metered plans and/or on mobile and having to reload a huge picture again and again is annoying to say the least. 

 

To answer your question, it varies by CPU/socket technology and there's no one answer that applies to all of them but a crude simplification would be that the "CPU package" sensor is in the CPU silicon package between the cores and the "CPU" sensor is under the CPU on the motherboard. The package is what you should care about.

Arctic Silver 5. The termal margin readings in Overdrive are  showing anywhere from (-)20-30*c

The temps look OK to me...

Thanks for the advice! I'll try to pick up more forum etiquette as quick as I can! So it would seem then, that if I was to replace the cpu, the "CPU Package" sensor would be replaced with it. And that would seem to fix my problem..
