Interesting, this little excerpt is from David Pogue rhapsodizing about the new iMac in the NY Times:

"Apple's chief, Steve Jobs, has gone on record as loathing the noise made by computer fans (the spinning kind, not the human kind that show up at Macworld Expos). Considering the heat generated by its 1.6- or 1.8-gigahertz G5 processor, the iMac's silence is quite an achievement."

My TiBook, 1GHZ, Superdrive feels like it's gotten noisier in the 2 years I've owned it. Upgrading to 10.3.5, resetting PMU and PRAM have had no effect either. Oh well. Temperature Monitor for the past couple of days shows me running at a steady 100.4F during the day. And it's gotten chilly here in Seattle! Weird.

Fans have a tendency to get noisy with time due to 2 things:

1. Wear on bearings
2. dust buildup (cause of #1).

both cause the fans to be less efficient, which on auto-sensor fans causes them to rev up to higher speeds to do the same thing they did before.

That's why sometimes cleaning them up or replacing them is a good idea

hard to get inside a powerbook though =(

That was my next question: is a can of air good enough, or do we need to get to those 17 itty-bitty screws and take things apart?

Former = easy and good. Latter = hard (for me) and likely not to happen.

Then there's the question of whether it's better to suck or blow. No bad jokes now.

"It's MegaMaid, sir: she's gone from 'Suck' to 'Blow.'"

Hey, I have a Ti/Ghz, and Temperature Monitor says that I don't have a temp sensor. what gives?

Same here�Ti/1GHz PowerBook, and no temperature sensor. My CPU is a PowerPC 7450. What kind are you using that's giving you a temperature reading? (type "hostinfo" into the Terminal)

I typed this into terminal and got the same results returned: I have a PowerPC 7450 CPU.

I looked in Temperature Monitor Help and found this though:
-----------
Which Hardware is Supported by the Application?
This question cannot be answered easily because Apple very often performs "silent product updates" that change the technical specifications of a model series without notifying customers. Some computers of the Apple Cube series for example are capable of providing temperature values while others are not.

Temperature sensors can also be part of graphics cards and hard disks. These components can also be different from computer to computer. To test whether Temperature Monitor or Hardware Monitor are supporting your system there is no other solution than to start one of the applications and have your computer analyzed by the program.

I seem to recall thinking that it wouldn't work when I first looked at the app before downloading it. But it appears to be working (both in Jagwire and Panthwire too).

I think the temperature-reading you gave us corresponds to your hard disk and not the CPU. On my 1GHz TiBook, Temperature Monitor can only measure the temperature of the hard disk.
