    The new Macbook air 13" ultimate has just arrived.
    Great new laptop, but if i play two 1080p youtube-videos the temps go as high as:
    Cpu: 187F / 85 C
    Northbridge: 154F / 67 C
    fan: 6495 RPM (loud)
    With a 75% cpu using rate.
    (I read this out with the istat pro widget)
    EDIT: Room temp = 20 C

    This is not normal. Way to hot.
    Do you guys have the same Temps?!!

    Those temps are completely normal when the CPU is under load. Today's CPUs can stand up to 105°C before they should shut themselves down

    Are you running Flash content or h.264 content? If it is Flash, consider installing the Flash 10.2 beta, which has better hardware acceleration features. That may reduce your CPU utilization if the video is coded to take advantage of hardware acceleration.

    Great idea, but that isnt the problem. If these temps can reach such a height, maybe there is something wrong with the cooling-pasta.

    Well, hellhammer thinks it is ok. I'm not sure. i need confirmation of other macbook air users who wants to play 2 1080p youtube-videos and write the temps down in this thread.

    It will make me very happy. :D

    Yes, it's normal with Flash content.

    I play a Flash game called "Madden Superstars" and the CPU temps will stay around 91ºC all the time with the fan at 6500 rpm.

    What is your room temperature? Here it is 20 C
    How much % cpu-time does this game take?

    ...

    I tried flash 10.2 beta on youtube content and didn't notice it decreased my cpu utilization at all. running like 360p res I think it was 30% with 10.1 or 10.2

    Room temperature around 20-25ºC.

    CPU at 100% or more (103% right now) most of the time.

    I have the 13'' Ultimate model.

    Which settings did you use?
    Did you take this shot at 1 minute of stress-testing?

    Are you watching vids with the Air on your bed or any other soft material underneath it?

    Any notebook will run hotter if it's being insulated by the material it's sitting on.

    I just selected some settings, I think they were big, 100, 16. As long as the CPU is maxed out, it's fine. I took the photo when the CPU temperature settled down, maybe around 1 minute.

    Ok, thats the same as me. I think it is normal then.

    But when i lay my ear on the left side, where the fan is placed, i hear a electral sound or something, it can be also the fan.
    I hear that sound and the whoosing. (2000 rpm) You too?

    Maybe broke bearings? or? What do you guys think?

    Sometimes when I view youtube videos (I've joined HTML5 but some clips are stubborn) it will get hot, and I found that even if it finished playing, if I leave that tab open the temp remains high.

    btw, this may sound stupid but why does CPU usage ever go beyond 100%? what does it mean? thanks

    Since your CPU has 2 cores, theoretically CPU usage can hit 200%. If it were a quad-core chip, it could go up to 400%.

    Snowcake, you may want to use CoolBook: http://www.coolbook.se/CoolBook.html

    I managed to undervolt my processor and get lower temperatures and more battery life. Here's a screenshot with my settings: http://d.pr/zUCZ (as I can use the maximum clock at the lowest voltage, I disabled throttling)

    Not true. Each CPU is different. Current AMD chips shut down at 62 degrees. These ones may be able to take that but I wouldn't be happy with it.

    OP you could try using cookbook. Lowering the voltage would decrease the temps.
