I've been noticing that my 12in Rev C Powerbook is running quite hot these days, during its post Tiger install. So I'm just wondering how hot your Powerbook runs doing day to day tasks (like e-mail, surfing, writing). If you don't know your temp, use this free program to find out.

OS 10.4.0
Average Temp 105 F
Extreme Temp: Graphics Card (playing Oni) 173 F

"1130-140?"

if my 12" revC gets up to 1130, i get a feature article at macnn...

haven't measured it, but not much different than panther, in fact, sometimes seems better...

You never know. You could always cook with it.

cooking at 1130 degrees with milkmandan.

I'm a big fan of Mac & Cheese.

macintologist · May 10, 2005, 01:37 PM

About average, runs at 49-51 C, and that is with my fan constantly on (it goes up to 52C, turns on, then never hovers below 49, since 47 is whats needed to turn the fan off. Very annoying!)

49-51C = 120-124F

I don't understand why people measure CPU temps in fahrenheit. Fahrenheit is what you use to speak casually about the weather outside, and on the news, like.."oh it feels like its in the high 80s today". Celsius is used if you're in somewhere other than America, and/or for more scientific temperature measurements, like CPU temps.

Silly people.

I'm usually in the mid to high 40's on auto and the mid to high 50's on highest cpu, this is with a 1.25 GHz 15" AlBook.

I liked having the ultra extreme heat option. Oh well.

Scooterboy · May 10, 2005, 11:16 PM

Normally, when just web surfing or email and such with iTunes runnin', my PB sits right around 44.8ºC. That's with ES setting at "Automatic", and 49ºC running one o' them gorram HD Trailers with ES set to "high".

madmacgames · May 10, 2005, 11:31 PM

there are 5 sensors... which one are you looking for?

macintologist · May 11, 2005, 01:23 AM

Scooterboy,

That's because you have a 17" PB which has a larger surface area to conduct heat. If you had a 12", or at least the rev A one, then it would be much hotter, like 49 and above, and like 54 when doing more intensive stuff, and 59 during games!

bimmerphile · May 11, 2005, 04:49 AM

The fan whips and wails....usually around 50˚C (~125˚F)

Randman · May 11, 2005, 04:59 AM

My 17 is running a few degrees cooler, on average, in Tiger. Right now, it's 107.2 (41.7).

xi_hyperon · May 11, 2005, 07:24 AM

51.8°C

PB G4 17" 1.33Ghz

vtgts500kw · May 11, 2005, 08:46 AM

43 degrees celsius

MilkmanDan · May 11, 2005, 01:44 PM

Stupid Metric System. Thats all I'm saying.

My car gets 4 rods to a hogshead.

s_ton · May 11, 2005, 06:43 PM

CPU: 46-48 Celsius. 12" 1.33GHz.

macintologist · May 11, 2005, 06:54 PM

Milkman, metric pwns you.

I'm an American fahrenheit user btw, but when it comes to CPU temps, Celcius is what I'm used to.

I'm not used to thinking of F temps above 110 or so. Celcius seems like more of a natural more scientific unit of measurement for CPU temps.

tictactoe · May 11, 2005, 09:23 PM

Battery Temp: 95F
Processor Bottomside: 130.1F
Processor/Controller Bottomside: 135.1F
Power Supply Bottomside 126F
HD: 111.2F
Trackpad: 102.2F

Ever since I installed Tiger, my computer has been running a little hotter than normal. My XBench score is only .15 more...

MilkmanDan · May 11, 2005, 10:28 PM

And for a while there I was afraid I was running too hot. Then i forgot that I should never put my laptop on my laps, when I have shorts on.

jdiddy · May 11, 2005, 11:27 PM

My 12inch 1.33ghz 1.25 was running a little hot after doing and upgrade install of Tiger, about 10 degrees Celcius hotter then normal. Virex was eating up 90% of my cpu and I didn't realize it till last night. I ran a unisntall script restarted and I'm back to a normal 46 degress celcius. My laptop was running at 61c during a file transfer which was much to high.

macintologist · May 12, 2005, 03:26 AM

ididdy, that's why I recommend you install both Temperature Monitor (w/ Temperature Monitor Lite) as well as MenuMeters so you can constantly and painlessly monitor your CPU and temp at all times. It's better than not knowing why your PB is getting so hot.

jdiddy · May 12, 2005, 05:54 AM

I already had Temperature Monitor installed but thanks for MenuMeters!! Thats a awesome program. Althought I'm wondering why MenuMeters shows my memory usage to be less then Activity Monitor which number is more accurate?

Randman · May 12, 2005, 05:59 AM

MM does a sampling. Check the preferences on how frequently it updates, closer to real time should match Activity Monitor closer.

Squelch11 · May 14, 2005, 07:52 PM

I have a brand new 17" that I just got yesterday. I downloaded this program, but when I start it up it tells me that the sensors don't update, and all it gives me is the temperature that they were when the program started. Anyone know why? Thanks.

Sean

MilkmanDan · May 15, 2005, 03:03 AM

NO idea, did you check the developer page?

Squelch11 · May 15, 2005, 12:33 PM

I looked on there, but then I downloaded that other program, the MenuMeters program, and it works, so it's all good. Thanks.

tkmd · May 15, 2005, 10:08 PM

about 120 F (49C) I run my 1.5 PB in auto mode fan will always kick in at 145 (62C). In fact I have never seen the temp go abouve 145.3F. I wonder if someone with th newer generation PB (1.5/1.67) can chime in on temps when in auto mode. Arent the chips cooler running in the current crop of PB as opposed to the previous versions? (1.33/1.5)?

MilkmanDan · May 15, 2005, 11:47 PM

They should be, if I remember my chip info correctly. Then again Apple has made great strides in reducing overall temperature and temp dissipation. I remember how my room mate had a rev a 12in powerbook and it got super hot just doing anything. You couldn't even have it on your lap (his poor manhood). With my Rev C its never a problem, at least when i'm not playing Sim CIty 4.

For Temperature Monitor.. i states that ..
You should be aware that the current Mac OS X version does not trigger updates for the sensors listed below. The readouts will only reflect the situation when the computer was started..
Other sensors and the cooling control of the system is not affected.

I would like to know what you enabled in MenuMeters to show the temperature..

What does it mean when the application shows a warning message about "non-refreshing sensors"?

On certain Macintosh models, Apple does not support that some particular sensor readouts are continuously transferred from the cooling control drivers to the user space of Mac OS X. This means application programs are unable to read updated values from the affected sensors, only the kernel itself has a chance to get current readings. The displayed values only reflect the situation at boot time - they are not updated while Mac OS X is running. If you have such a system, please let Apple know that you like to have the feature to get up-to-date readings built into future versions of Mac OS X.

it doesnt perform

it doesnt work with my 15" tiger 1.67pb either.

ericssonboi · May 18, 2005, 03:08 AM

Yea.. i understsand.. its one of those things Apple updated..

I thought Squelch11 mentioned that they got it to work through MenuMeters since they just got their new 17PB (i assumed it was a Rev D model).. ?

I doubt it, 'cause i just got mine 15" a week ago.
btw, i was wondering if anyone have used these tempature monitor

Temperox , ThermographX and ThermoInDock 0.9

thanks

dog2van · May 19, 2005, 07:18 PM

anyone hve problem running tempature monitor with tiger10.4.1?

Yeah, I'm dumb - I was away from my 17" for a bit, so I am just responding now. Looking at it tonight, I realize that it was just the type of display that it was showing, not an actual thermometer. There's the option to show CPU usage as a percentage, a graph, etc., one option being to show it as a thermometer. I misunderstood and thought it was an actual thermometer. It's not - it's just a type of display. Sorry!

amazing · May 23, 2005, 06:52 PM

I like Temperox, because it also shows the fan speeds. The current version isn't showing the battery temperature but the important temp is the power supply bottomside. Presumably that's the same thing as "graphics processor die" in Temperature Monitor? Just going by the reported temperature, not the different nomenclature...

Anyway, rev C 12":
85 F outside temp, 75 F inside
power supply bottomside 54.75 C/130.5 F, rear left fan at 4415 rpm, auto energy saver setting.

Frankly, I don't remember the fan coming on as often or as long in Panther. It's only since upgrading to Tiger that I've been wondering about the objectionable fan noise, so I didn't even monitor the temps in Panther.

Neither Top nor Activity monitor show anything hogging the CPU, so what's the deal? Did Apple set the threshold temp in Panther different from Tiger?
