Holy crap!!! my ibook is at 161 degrees fahrenheit...

[Dustintendo]

when will the fan turn on?! this is freaking me out

[Dustintendo]

ok, it just turned on..but isnt 161 degrees a little hot? shouldnt the fan have turned on earlier?

[BlizzardBomb]

I think the iBook can survive at that temperature (just). I think 190F is the max, not too sure though. How hot is the place you're in?

[SpaceMagic]

Hmm, I don't know. 72c 161F seems a little hot to me! But not impossible. I had an AMD Duron which ran at 85c and was fine. Dunno about the iBook though.

\not very hot at all, i read that the fan usually turns on at 67 celcius and mine went on at 72..i guess its not too bad

edit: also i was running folding@home to test the fan, and i know that heats up alot, and very quickly, so maybe that was the reason

[iGary]

Pffft....

My A CPU is spiking 202 F on my PM during a batch right now. :eek:

[mpw]

Where do I stick the thermometer to take the measurement?

[berkleeboy210]

Here's what my PowerBook Reads now

Processor/Controller Bottomside: 62.8 C
Processor Bottomside: 60.5 C
Power Supply Bottomside: 53.8 C
Trackpad: 41.0 C
Battery Temp: 32.0 C

I'm using Temperature Monitor for these calculations

[joecool85]

Wow, I've never seen my PB above 144 F! That was running Seti@home before I had the cooling pad, now it doesn't get above 135F or so.

[BlizzardBomb]

I use temperature monitor lite. Pretty good for me. :)

[highres]

where is everybody getting these CPU temperature readings from? It's not Activity Monitor is it? Or are you all using a diagnostics tool?

[BlizzardBomb]

With the thing I just said :rolleyes: Here's the link http://www.versiontracker.com/dyn/moreinfo/macosx/19994 :)

I was writing my question when you posted your answer, I will check out temperature monitor lite and see if it is worth downloading and installing. Thanks for the link.

[BlizzardBomb]

No probs :)

[ohcrap]

Why are everyones readings so high!?

Temperature Monitor:

Processor Bottomside: 24.5c
Power Supply Bottomside: 24c
Trackpad: 23.5c
Battery: 24c
Hard Disk: 36c

[Erendiox]

I don't know how you guys are getting these crazy readings. My ibook cpu temperature never exceeds 135 f. :rolleyes:

[ham_man]

Mine is running at 120 F now...

[Verto]

My iMac gets up to 190F :(

[ohcrap]

My iMac gets up to 190F :(
:eek: That's insane. The highest I've ever seen my PB at was 89.5 F.

[akm]

Depends on what you are doing. I've been running distributed.net (so CPU load tends to stay at 100%) and my readings on my iBook are:

Temperature Monitor:

Processor Bottomside: 68.5C/155.3F
Power Supply/Memory Bottomside: 52.8C/127.04F
Battery: 32C/89.6F
Hard Disk:63.5C/146.3F

[ohcrap]

Maybe I don't have any apps that cause that kind of CPU usage. My worst is when I am burning a CD, listening to music in iTunes, working with widgets in Dashboard, and chatting in iChat, and maybe a few other apps running in the background that I'm not really using like Word, RapidWeaver, and Image Tricks. :rolleyes:

[puckhead193]

geez, what are u people doing on your machines....

[superbovine]

when will the fan turn on?! this is freaking me out

run for your lives it going to blow!

oh wait... nm

[mkrishnan]

Hmmm... so I noticed that since I upgraded to 10.4.2, I get a lot more fan activity. And I just turned back on the temp monitor widget, and my fan was running at about 58C, a temperature at which it sounds like it would not run for many of you. Hmmm.... Well, I guess since it came and went for others with dot upgrades, I too will hope that 10.4.3 makes it go away.

I've never once heard a fan running in my PB, and I work in a dead silent office (unless I'm blasting iTunes). :D

My fan hardly ever came on until 10.4.2. And you can definitely easily hear the fan when it comes on. It is fairly loud. Even now, <5% of the time. But it was <<1% of the time before.

But my iBook would almost always run the fan if a CD was ripped at high-speed. And occasionally because of heavy processing.

Which PB, FWIW?

[mscnln]

It would be nice if the temperature sensors on post-febuary powerbooks actually updated in OS X...

[ohcrap]

15" 1.5Ghz G4.

Always quiet as can be, didn't notice any difference after installing 10.4.2, although it is still listed in the Software Update even after I installed and rebooted. Thinking of going at it again, but then again, maybe not. :rolleyes:

[jamesW135]

My iBook doesn't go past 80. :)

That's strange. What does about your Mac, from the Apple menu, say?

Anyway, yeah, I think if/when the fan turns on, you will definitely know it. :D But fortunately, its duty cycle, even on my computer now, which gets more fan activity than it ever used to, is not high. Nothing like some of those notebooks where the fan runs all the time and annoys the hizzeitch out of you. :)

[zflauaus]

Wow. I've gotten my iBook up to 150 degrees F and the fan turns on. That's playing Marble Blast Gold, because I have nothing else to do with my free time. And plus I don't have any other games. :D

[ohcrap]

I got it worked out. I had that version number confused with a particular software update. Stupid noobie-me. lol :D

[iEric]

I installed it on my iMac G5 when i first got it and the stupid monitor went up and down, up and down - so i just uninstalled it. It worked on my G4 well though. Is this a compatibility issue or something?

[Apple!Freak]

That's nothing. My dad's PB typically gets up to 190F. It gets so hot, to the point you can't even touch the bottom of it for more than a second.

[ohcrap]

After installing the replacement battery from Apple for my 15" PB, all readings have gone up about 10 C or so. Still reasonably cool, but not like before.

Why doesn't this stupid program update itself? I have it set to update the temperatures at 1 second intervals and it just stays put..

[Hemingray]

geez, what are u people doing on your machines....

Frying eggs... :p

[chaosbunny]

Seems a little hot for me too.. my pb is on 120 degrees F right now, after 6 hours of graphic design use..

Just for you to have another value to compare..

[ph0rk]

At least for the rev. D powerbooks and temperature monitor 2.5, it gets readings at start-up, they do not refresh. (until you reboot).

So claims temperature monitor, and with a (reported) CPU bottomside of 57 degrees celcius after 16 hours of sleep, I believe it!

[caveman_uk]

Temperature Monitor:

Processor Bottomside: 24.5c
Power Supply Bottomside: 24c
Trackpad: 23.5c
Battery: 24c
Hard Disk: 36c
Is your powerbook one of the current (Feb 2005) 15" models? If so they don't update the temperature to programs like Temperature Monitor. The program can only see what the temperature was when the machine was turned on....so my guess is your office is at 24 celcius!
;)

EDIT: Oh damn. I didn't read the last post. Sorry for repeating it.

Right now my iBook's at 89F and that probably the coolest its ever been. It usally runs around 110F and I have gotten it pretty hot from running games and multi-apps at once. I don't know how you people keep yours below 100F all the time....

Oh, and by the way I use a widget to get the temp reading. Just look under the widget downloads at Apple and find one you like.

[kneeboardchick2]

I find that my ibook runs at different temperatures at different times of the year, in different rooms and at different altitudes. For example at my parents' this summer it was running 57c as average and now it's down to around 43c. Also the temperature at which the fan kicks on varies as well as how long it stays on for and what temperature it turns off at. Good thing its quiet, because sometimes its on for quite a while.
