I'd like to request feedback specifically about fan noise and fan usage in the 15" Alloy PowerBooks. I have the 1GHz Titanium and the fan(s) are virtually always on, non-stop. This was not the case w/ my previous PowerBook, an 800MHz/DVI. It ran quiet most of the time, usually only kicking on the fans w/ Photoshop.

So now that the 15" Alloys have been out there for a while (well, those who haven't been sending them in for repair) I thought I'd ask what your experiences have been over the past couple of months in regard to fan noise and fan use/amount.

Thank you for your time and any feedback you can give me.

PS - Does the 'chirp' affect the 15" Alloy or only the 17"? I've noticed a chirp on my current Titanium when my HP Officejet 6110 is connected and idling, I don't know if this is similar to the Alloy chirp I've read little about.

This powerbook is always quiet, but i do run it on reduced processor all the time, it has never come on in the 4 weeks i have had it now.

But last night i actually heard the Virtual memory on the HD last night, there was the pause and the HD noise.
I still have the stock 512 RAM in it, but last night i was using Indesign, Appleworks, iTunes, Safari for the first time all at the same time.

Other than that its been quiet.

I have the 1.25Ghz model as well.

I don't ever recall noticing the fan. It's probably come on (and it does get rather hot), but it's not loud enough to be distracting. Of course, I do often play music on my computer, so that would probably drown the fan out...

I run my aluminum book on full speed all the time and the fan hardly ever kicks on, and when it does it's pretty quiet, at least comparied to a tiBook or my old pismo.

Whisper quiet this machine is.

Yeah, the 15" is basically silent when it's on without the fan. When the fan comes on, it's only slightly more audible. It's great

... and then from a completely different point of view ... my 15" 1.25 5400RPM AL fan comes on a lot ... especially if I actually keep it in my lap ... energy settings "automatic."

Every other day or so, the second stage fan (the one on the left) comes on with a helluva-distracting clatter ...

Regardless, I LOVE my aluminum beauty!

My fan comes on quite often, but I'm usually crunching numbers pretty intensely on the machine. It consistienly comes on at 335K (144 F), and remains on until the temperature falls below 334K. I don't mind the sound of the fan --- it is a soft, fluttery sound, much different than the whine of the black PBs (I don't know what the TiBooks sound like) or iBooks (man, those are loud!).

I haven't ever heard a second fan come on.

Yeah my fan hardly ever comes on, and when it does, it purrs...my TiBook DVI 800 had a much louder two-stage fan, and the high stage was very loud and anoying. This here 15" Aluminum is much, much quieter.

And the keyboard is awesome. I'm a serious typist, and this thing is a joy, has great action, etc.

I've had mine for a month or so now, and I've only heard the fan a few times - maily when doing a very long (10-12hour) bit-torrent download.

Even so, when it does kick in, it's still way quieter than my old G3 Yosemite.

Thank you for the feedback so far guys. Sounds like on average it will run more like my DVI/800 did and maybe even be quieter. I'm glad the keyboard was mentioned as well, I haven't gotten a chance to try out the 15" Alloy's keyboard yet and I was wondering about it. My 1GHz Ti has the slightly "spongy" feel to it on the right half, I've tried re-seating it several times... again, my 800 was perfect in this respect as well :\ Still far better than the feel of the (virtually exact same) keyboard used in the Lombard, Pismo, and first gen. Titanium. Maybe I'm just too demanding when it comes to PowerBooks :|

Btw, someone mentioned temperatures of the processor... Does the G4 chip in the Alloy's support temperature output to programs like AquaMon?

Thanks

Yes. ThermographX and Temperature Monitor utilize the probes. I use TM mostly, though ThermographX tracks 4-5 sensors.

Yeah, I had an Ti800 and it was pretty quite. My new 1.25GHz PB is definitely the quietest by far.

I had a Ti867 before this and I notice that the fan did come on all the time.

And yes, the keyboard is a lot better than the old removable ones.

I have both a TiBook 500 and a Al15". The AL15" is much quieter and it is rarely on. I've played EQ and a few other games for hours and it maybe kicks on 3 minutes per hour or I just don't notice it.
If a group of mimes are miming a forest and one falls down, does he make a sound?
