How hot is this MBP?

    Reading a recent post make decide to log, again, working temperatures in my MBP Rev.A 15". I used Temperature Monitor ver. 4.2. Results are shown in the images attached. Numbers speak by themselves.

    The "test" isn't more than running Safari, Firefox and Parallels with XPSP2 executing an ATI OpenGL demo. The demo is run for a couple of times with some idling in between.

    In the first image, you can see the 2nd core temperature of is 96 C, but the first core is way to hot that the sensor has "passed out". ( Over 100 C ). Fans kick in soon, so the maximums are reached for no more than 30s. each time.

    The second image shows the highs and lows of the last last 1h30m. It doesn't log with accuracy but it gets close.

    Supposing the readings are accurate, I think this MBP is way too hot: I can't even touch the bottom of it with my hand. How can I ask Apple for this to be fixed?

    As a curious thing to me, the main heatsinks values comparatively don't change much. See for instance the GPU heatsink.

    Your opinions are very welcome. Thanks

    Indeed they are. The default is 1000rpm and they stay there most of the time. They only kick in when the temperature reaches about 90 C, After cooling down to around 80 (@6000rpm), the fans start slowing down, and the story repeats.

    since I installed smcFanControl, I have a better experience, setting the fan to full speed before a GPU or a Parallels session, but I shouldn't be doing if the machine were working fine.

    I must say that it never has frozen or reset by itself. It just keeps working.

    You don't say.....:rolleyes:

    That looks like a problem with the timing on your fan. I'd call Apple and see if there's anything that they can have you do over the phone to test it or something. That's a HIGH temperature...

    Seems pretty hot to me. If your close to 100C regularly then it does sound like there is a problem. If it occasionally went into the 90s and the fans brought it back down relatively quickly that is probably fine, but if it is pushing 100C on a regular basis, I'd take it in and see if they would fix it. If they won't, you could always do the reapplication of thermal paste yourself and see if that doesn't make a difference. If you still have warranty left though, I'd let Apple do it.

    So, would you guys say, if i'm playing WOW and it gets up to 90c and the fans kick in a bit to bring it down to somewhere between 77c and 86c, that those temps are normal and that i'm ok? I know i shouldnt really sit here and read every bad bit of info about these things, but its making me parinoid that my computer might overheat or just have a lower lifespan because of these things running so hot. To be honest though, the case of my sr-mbp doesnt get quite as hot as my friends October 2006 CD mbp. I dont know what his temps get up to but his case definitely gets hotter than mine.

    Just out of curiosity, does iStatPro show the same temperature readings?

    I've just installed the widget, ver. 4.12, and yes, it shows the same readings, though it doesn't have the individual CPU core temperatures, just the "Diode" one.

    How hot is the room that you use the computer? As an example, i had mine the first day i got it, in a room where it was very warm, somewhere just over 30c, and the idle time alone was nearly 65 - 70c, however, once the AC was turned on, and the house became cool, my idle temp has lowered down to about 42c

    At this very moment, the "official" outside temperature is 23C, and the Ambient Air sensor inside the machine steadily reports 27C, as shown in the attachments, though I've had readings ranging from 23C to 28C.

    Well, I believe ambient temperature matters, though, only to the touch it seems to me, as the entire case is dissipating heat. After half an hour of running the fans at 6000rpm, mostly idling, the readings are now 46C for the cores and 35C for the heatsinks. Bottom is cool enough at 33C. HDD temp. is too low to have a reading.

    Hmmm... If you have it on 6000 rpm, i'd imagine your temps would be more around 40c or so, maybe less.

    If you were to let the fans set back to the default 2000 rpm i imagine your temp would shoot right up again?

    That's right.

    The default fan speed for this Rev. A (Feb'06) is 1000rpm. The minimum I mostly use is around 2500, with some more speed for the left-side fan.

    Right now I'm setting the minimum rpm with 29C of room temperature (28C outside), and CPU 90%+ idling, and battery recharging, as I type this the temperature is climbing up from 54C to 66C (core averages). Still at 1000rpm though. Bottomside is scalding at 45C.

    One question: Can 75C at the memory controller sensor hurt the RAM?

    One more test

    For your amusement, owe or sorrow, whichever may suit you, here is one more test.
    Less than 5 minutes of a GPU intensive program and two browsers open.
    The machine is well ventilated on top of a glass covered table, at a comfortable enough 29C ambient temperature. Battery recharging.
    Again, numbers speak for themselves.

    Question: How can I convince the guys at apple that I need them to fix it.
    Might I be entitled to a replacement or something? I already had these issues with this MBP:

    Dealt with:
    DOA: Logic board and battery replaced
    Dead battery: Replaced
    Recalled battery: Replaced
    Malfunctioning magsafe: replaced

    Whine: "your are hearing something else" (At least they have acknowledged the problem now).
    Extreme heat: "It's all at acceptable levels"
    LCD lid bending: "Your fault, improper handling" (I believe that closing the lid with the machine being so hot i what causes the bending. I don't close it anymore before cooling it down).

    Thanks for reading. Sorry for all the rants.

    Hmmm, I sometimes wonder if the geniuses think that the term 'within acceptable tolerances' ,when talking about heating issues, are actually thinking that if the temperature is below spontaneous combustion then all is fine.

    Just a random thought

    what can anyone expect from apple anymore?

    My mom bought a MBP last December, cuz I certainly wasnt about to after all the reports of how boiling hot the REV As got. I read that this one was supposed to be cooler. OK. Well, its still pretty hot, and no, I dont have a
    thermometer for it. I wouldnt dream of putting this thing on my lap, and it seems mandatory to get one of those rubber insulating/breathing platforms.
    This is just from doing batch conversions of RAW files to JPEG etc. I wouldnt dare to run a two-day 3D render on this machine, although its clock speed is far better than an old G4, at least, that is, at SIMPLE renders. Complex renders with reflections and volumes still seem to be plenty slow at rendering. The point is that I cant imagine running this machine at high temps for several days. Basically, i want to tell Apple to shove it at this point.

    No mini upgrade for nearly a year, quad core Intel 2.4 ghz and motherboard combos selling online for $600, with $100 500gig HDs
    but MR JOBS can't even dump out a cheaper $1000 tower because it would rob from his overpriced pro towers. This coming from a lifetime mac user. yeah, I know, the iPhone is so great. Someone needs to explain to me why I would pay $600 plus subscription for a glorified cel phone. My friends have internet access on their phones. Great.
    I dont want to do 3D rendering or audio production or photo or website editing on a stupid handheld phone. Good for travelling...OK.

    Better not get as hot as the laptops, or it will be great hilarity indeed. Apple is no longer the company for boutique multimedia users who want a desktop, and the laptops arent a viable substitute for the desktop.

    I wasn't aware we had a "Random Apple Rants" subforum here in the MBP forum. Or maybe it should go under "Assorted FUD"?

    ... and maybe your posts should go under "I suck up to Apple no matter what." Well, to each their own.
