    Sup guys. I been really curious about the temperature of my computer. Recently, I downloaded istat pro just to see the stats of my computer. I noticed that temperature is kind of high. For example, when I am using firefox and openoffice, the CPU A is 49 to 50c. I don't know if this is normal or not.

    Also, when I use vmware fusion for windows xp, the temp for CPU A gets around 69 to 71c. Is this completely normal?

    Here are the stats of my unibody macbook pro:
    2.4ghz
    2.0 GB of RAM
    250gb of hard drive
    15 inch
    better words, it is the stock version.

    Istatpro as of now:
    HD Macintosh: 37
    CPU A: 50
    Enclosure Base 35
    Enclosure Base2: 35
    Enclosure Base3: 33
    GPU: 45
    GPU Heatsink: 42
    Mem Controller: 43

    I'll appreciate any feedback, thanks.

    you are going to find that the temps that ppl's computers run at is pretty random check out this forum.

    I have the exact same set up as you:

    sometimes the unibody is nice and cool and other times it is warm...not hot. but here are my istat #'s and almost the same as you!

    HD Macintosh: 33
    CPU A: 48
    Enclosure Base 31
    Enclosure Base2: 31
    Enclosure Base3: 29
    GPU: 43
    GPU Heatsink: 38
    Mem Controller: 41

    You should turn it to fahrenheit because I don't know the conversions lol. But when I am gaming my CPUs can be like 160F or so. Pretty normal for the most part. On average they are 130F. The Diode is usually the warmest and it sits at 150F on normal or about 180F when gaming. Runs great and fans kick in and out when needed.

    Thanks for the replies. What I just want to know if it is completely normal to see the CPU A temp at around 45 to 50c is normal for example:l under firefox and openoffice. The reason I ask is because yesterday, I also noticed my macbook pro heating up all the way to 69c when I had it laying on my bed. I felt the whole notebook real hot.

    So, best of all, is this totally normal? Or should I give a visit to Apple?

    It's perfectly normal. Quick guide to chip temps (in Celcius, which is always what is used for computer temps. Note this list only applies to GPUs and Notebook CPUs. Desktop CPUs generally are not as tough, since they don't need to be):


    40-50 = Normal idling
    50-65 = Normal load
    65-75 = Heavy load, probably want some extra fans when you get to the top of this range.
    75-90 = Getting close to the danger zone, FANS NAO!
    90-100 = Stop what you're doing.
    100-110 = Things start throttling down to protect themselves. Take the load off, and check the cooling system. Make sure it is installed properly
    110-125 = System will make a forced shut down, and will not power back up until the temps drop off.

    The problem for me is not the temps so much as how hot the palm rest gets.

    Saying 65 degrees is normal load is fine. However is that means you can't rest your hand on the laptop without it burning there's a problem.

    That's what I'm finding at the moment. That under load the laptop gets too hot to comfortably work with.

    This is why I'm looking into getting the fans always on higher.

    Regards,
    Simon

    Actually, a easier reading is:

    Anything below 95 deg C, don't worry.
    95 - 105 deg C, start worrying a little.
    106 deg C or higher, if the system still doesn't shutdown yet, you can kinda start panicing.

    Diode temp cannot hit above 106 deg C before damage is incurred.

    Mine are about the same. Seems normal. I've had laptops that read cooler temps at idle (mid 30s) but they were a lot louder..

    Thanks for the feedback guys. I guess I overreacted because I never noticed the heat on my mac until I started analyzing it. I guess that when you don't have your mind on it, you won't notice the heat to the touch lol. I never even realized that when you run vmware fusion (xp) the temp gets up to 71c. I guess everyone here feel the heat surrounding the rest of the palm. I'm not alone heh.

    Sitting basically at idle on my MbP 15" (late 2007 model) with 4 GB of RAM, here are my specs:

    HD 38
    CPU A 60
    Airport 55
    Enclosure 32
    GPU Diode 64
    GPU Heatsink 58
    Heatsink A 52
    Heatsink B 40

    I'm currently (as I type this) running the following apps:

    Entourage
    NeoOffice
    Firefox

    Under vmWare Fusion:
    Powerpoint
    Word
    Excel

    Lots of apps running, and the unibody is definitely hot to the touch, but the fans are not screaming. The fan speeds are: 2002 and 2003 RPMS for A and B

    I also have the unit sitting on a new Thermaltake T1000 stand, which has a 120mm fan and is very quiet, but doesn't move much air. I just started using it, so I don't know if it makes a difference. My previous Belkin stand (with dual 80mm fans) moved a lot of air and made a big difference, but it was LOUD and annoying (and finally broke)

    Is yours the early 2008 MBP or the late 2008 uMBP.
    Either way mine is the late 08 uMBP my temp idles at 32C to 40C with safari open with several tabs on the go.

    The temp of my laptop depends on whether its on my lap or on the desk and the temp of the room.

    Right now Im compressing a video file with handbrake and using safari, my overall temp / CPU is 73C.

    I think the best advice is, if its under 90C don't panic :D

    A slight side step, if you are worried about the temp, download SMC fan controll, the fans idle at ~ 2000RPM I set the new default at 2500RPM.

    This keeps the Laptop around 40C and the noise is not audibly louder, even 3000RPM isnt loud.

    At the moment my fans are running 6208RPM :eek:

    I'm just running itunes and safari now and my laptop has been on pretty much all day and both CPU cores are around 45 degrees C. I was doing some intensive stuff earlier and it went up to 80 which is the highest i've seen it.

    Everything below 80 degrees Celsius is acceptable under a full load. You should be around 40-60 degrees Celsius under a light load.

    what's going on if my temperature is 70 degrees even if nothing is open, nothing runs? that's too high, it wasn't like that before.

    What speed are your fans running at? Also, how much of your CPU is used?

    My temps are typically
    40-50c idling
    50-65 Normal usage

    I do notice when running VMware that does cause an uptick in my temps even if I'm not active in it, but the guest OS is up and running.

    2000RPM
    1-7% CPU Usage using istat.
    i had the temperature around 40-50 before. I'm trying to figure out if it's some software or service causing it, but no luck... I just don't know what it is

    Heat

    I'm mainly concerned that the plastic keys will get warped by the heat. When I use the GPU it is 20 degrees hotter. I don't see a GPU temp in iStat pro

    Those temps are completely normal. They will also vary greatly depending on the ambient temperature.

    Heat

    I know that temps are subjective but what I'm saying is that when running the GPU that area over the keyboard on the left and the vent under the screen hinge get really hot. Temps jump from 53 C to 74 C average. I don't see how it can't damage the keyboard. Apple says cautiously "very warm". Is this REALLY normal or is it something they will have to fix?

    it's quite ridiculous that when using 9600 the cpu gets hotter. I understand the GPU working hotter but CPU...

    Heat

    Right-as the GPU heats up, the CPU core temp goes up! What's up with that? SMC Fan Control AND iStat Pro both report a 20 degree increase in CPU temp when the GPU is in use. If it were just getting hotter under the GPU I'd dismiss it
