    Default What is a safe CPU operating temp under full load? (8662)

    Just as the title says. I'm trying to figure out if overclocking my p9700 is an option at all. What would the max safe operating temp be under a full load on both cores in the 8662.

    Also does anyone have the PLL or the Sager 8662?

    Good evening and thank you for your post.

    I believe that anywhere between 40-65 C would be considered acceptable. Much higher then that at full load for short times would be ok, but I wouldnt want to push it too long at temps higher than 65C.


    thanks,

    Joseph L

    I waited for someone to take a stab at this. The thermal spec on the CPU you ask about is 105°C. Of course that is a max and you would not want to run close to that with any frequency.

    That said 40°C to 65°C is excellent. If under load you can operate in that range you couldn't expect much better. I actually read anything 80°C and under is both fine and realistic. If a system runs at 90°C and cooling measures have been taken then so be it. It will likely lead to earlier failure than cooler running CPU. That said if that means it fails in 10 years not 20 years that is hardly realistic concern. 10 year old CPU is a PIII 500Mhz.

    Be careful when talking temps as where that is measured at makes a difference. If you look at desktop specs vs mobile you will see the thermal specs for mobile are higher. But keep in mind this is not an apple to apple comparison. The mobile is a temp from what is called the "TJ" thermal junction. The desktop is from the geometric center on the topside of the processor integrated heat spreader.

    Joseph's numbers sound more like desktop numbers. Run something like orthos for 10 minutes I don't think most will be at 65°C or less I say up to 70°C/80°C is more realistic.

    I agree with powerpack. My Np8662's CPU got up to as high as 85-90C under full load. Thats with 4 hours of GTA IV everything set to high. Although if you're worried about temperature issues, then I'd recommended a laptop cooler. The Zalman Nc2000 is a good bet.

    Using a Zalman 2000 here on top of a lapdesk. Feels like an icetray under my notebook. Highest gpu temp I've hit , under full load, is around 50c !

    OK everyone going over 50C send your notebook back for service. Just kidding. Nice temps.

    Not really, but what is your max and what is the temp in the room? Have you cleaned your laptop out?

    It just changed when I checked it right now min 65 max 67. Room is alot cooler, does this effect internal temp?

    yes room temp affects the internal temp. The warmer the air coming into the vents the less heat can be transferred to the air from the warm CPU. So if you are in a 95 deg room and then move to a 75 deg room you are going to see a difference. Depending on the cooling system it might be a big difference.
