    Hi all

    I have followed the forum for a long time but never needed to post!!

    Now I do!!

    My new UniBody Macbkook 2.4Ghz is running at 80c on the CPU! It seems a bit hot to me, what do you all think? I have never seen a CPU run at this speed, I read an article that gave the exact model of this CPU but can't remember what it was, exhaust fan is running at 4300rpm at the moment.

    What do you all think?

    The good side of the grass.
    Yes, that's pretty toasty. Mine hovers right about 47-60ºC.

    Have you closed all applications and seen if that helps?

    If yes - how about a restart?

    Tried sleep and wake a few times with 10 mins or so in sleep, just done a full shut down going to see if she cools down, heatsink must be fitted properly if the temps are reading and the fan is stepping up and down?

    Maybe you are doing intensive applications? Mine hovers from 30-65*C (68 being the highest I've seen). Normally sending it to sleep for 15 minutes cools it down to 25*C. I still haven't seen 80*C, that dam near boiling 0.o

    Currently 41*C.

    I have a white MB and it easily reaches to 70-90C when using any multimedia intensive task (watching TV , burn DVDs etc). Fans go nuts as well of course. I do not think that's the problem. However, my new alu never reached above 70C (which I absolutely love!)

    Agreed. And the fans usually run around 2k rpm in my experience. I would see Apple about it.

    Mine is running about 47 to 78 c depend what you doing.

    47ish c - idle temp (2000rpm fan)

    50-60ish c - surfing internet and listen to itune (2000rpm fan)

    60-78ish c - surfing internet videos and itune (youtube and such as) (3100rpm fan)

    Hope this help.

    i was top gfx on warcraft last night on my 2.4 alu mb and after 2 hrs when i quit it was quite warm (mb was on lap), checked temp, 74 C, fan at 3570rpm, about 10 mins of idle later fan down to 1250rpm and temp was 45 c, mb on table.

    Id say if activity monitor is showing little cpu usage and your that hot take it in to be checked.

    Well it seems to have come down to 50c IDLE now?

    Seems ok to me, my pen drive was flashing before, now it isnt, I think maybe the laptop was indexing? Would this have caused this high surge in temp?

    Like I said it seems ok now but it would be good for other users to know what caused this!?

    In the land of no hills and red dirt.
    simple explanation

    As previously discussed, the 2.4 comes with options and addons that the 2.0 lacks. When you bought yours, did you explain that you did NOT want the beverage warmer option?

    Make sure you check Activity Monitor to make sure you don't have something chewing up CPU cycles like a run away print job or something...

    After using the MacBook for 2 hours, it reads around 50 degree C from istat Pro.

    Is it just the HD that you should look at the temp? Mine is running at 40

    To Carnivor: I though ~2000 rpm is the lowest fan speed of the new glassbook, but somehow yours fell to 1250 rpm? Mine is the 2.0G model, but can't imagine that to make a difference. Strange!

    Quick update guys, I have been running the machine for a few days at 35-60c with no problems at all.

    Just plugged in my 8GB Pen drive and started moving 5gb of data, as soon as this was done, the temp was straight back up to around 75-80c.

    Now I checked activity monitor and the mdworker seems to be the culprit using around 30-40% CPU

    I think this indexing process is causing the temp to increase, what do you all think?

    Sound normal to me, sir.
