    7805u: ACPI Temperatures getting too high?

    This is my second time having temperature problems with my 7805u, and last time it was my CPU and GPU getting too hot.

    Now it's the ACPI Temperatures, and they have been reaching 98 degrees or around there when I play MW2 or other games (After one game my ACPI Temps are 70 or more). I play my laptop on my lap :p, and I don't have any cooler for it. I also sprayed my laptop fans with compressed air already 2 - 3 weeks ago, so I kinda doubt that is the problem.

    Also when the temperatures reach around 90 the game starts stuttering, and begins to drop in FPS.


    Any help?

    I sprayed the insides with some compressed air. It did the trick a bit, but I need to open my laptop now and blow it from there.

    Did you overclock your GPU? Have you done anything with the laptop?

    I'll reply on your thread next time.

    have you tried changing the thermal paste?

    i really suggest not using the laptop on your lap not only because its uncomfortable after a little while but because the vents are easily blocked by where you rest it on your legs. you dont really need a laptop cooler but it does help immensely with keeping the hdd's cool. maybe intead of using it on your lap or having to buy an expensive cooler get something like i got

    My HDDs don't get as hot it's near the top right part of the laptop (near the CPU I think). I'll try spraying compressed air again to see if it works.

    Also I sit on my bed while I play on my laptop, so I doubt that's work.

    A little time ago my temps were extremely high and I didn't want to open the notebook. So I used canned air + vacuum cleaner (from the outside, at the same time; the idea is to remove with the cleaner the particles that the air hits) and now the temps are just like they were the first day I bought it. No need to open it.
    (They say that you shouldn't use air on it without opening it because the dust would just move from a place to the other, and maybe get to places where it's even harder to clean.)

    Yeah that's what I think happened, but when I sprayed the vents a whole bunch of dust came out. Now it works fine, the temps are regular

    It's not actually a real temperature. The ACPI "temp" is just a calculation based off other temps. The stuttering is automatic throttling that kicks in at 98C to prevent damage to the system. For most people, the 98 reading is meaningless, and removing the throttling through undervolting or other means and ignoring the reading is the way to go. Your components were actually probably pretty hot though. If this is a problem in the future, you might want to check this thread out.
