I have sent this notebook in twice for service due to high CPU temps. Using the "Core Temp" program I observed CPU temps reach 82C. Is this normal? How high can it reach safely?

Thanks all for your help!

Notebook processors can run quite hot without problems, compared to desktops.
82'C at no or little load is a tad high. Could not find temp spec for that processor, but think it will take 90-95'C without damage. Notebooks usually shut down automatically if a certain temp threshold is passed, to prevent the system.

Try using a can of compressed air... blow the air into the air vent of the laptop. You will see metal fins in there. In laptops, the air channels are so small and cramped that they easily get full of dust and such. Blow the dust away and it will help temperatures a lot.

Also, you can undervolt using K10Stat software.

Which CPU do you have? The Athlon II, Athlon II Neo, and other similar-generation chips in my experience don't run this hot...

Not sure, V140 series is all that I know. I wonder if this falls under the NVidia class action suit?

Anyone have more information about this?

Thanks!

I don't think so; those laptops don't have Nvidia chipsets. It seems something is quirky with the cooling though. Have you tried updating the BIOS from their website? Or checking in the BIOS to see if there are any fan settings you can change?

This CPU is one of the ones that's supposed to last long on battery, not draw much power, run really cool... you get the idea. Not exactly an extremely fast gamer CPU that runs at high speeds and gets really hot. I'd keep hassling them until they fix it or give you a new laptop. I know people who've had this model and it hasn't overheated, so something makes me think that there is something wrong with a part of your machine...

Check Task Manager, by hitting Ctrl, Alt, Delete. What is your CPU usage like? If there is a program running in the background, maybe Folding@Home or something using up a lot of CPU processing power, that can make the chip pretty warm... would you mind checking that and letting us know what all is running in the background?

i have the same processor on my laptop but the temperature dose not exceed 55 C

but how to know the max temperature that the CPU work correctly even when reach it, i think its written on the OPN number , but how to understand this number
, on the other hand , the official website for the AMD put the max temperature for the PCs processors and not the notebooks


help us if you can
