I'm having the same extact trouble with the same exact machine (also with 768mb) except I have a 17" Apple LCD. Mine is on an iCurve but it doesn't seem to help much. The fan wil…

The problem is NOT the Cinema Displays. It is Apple's. If you upgraded to 10.3.2, the fan settings were changed so that it would come on at a MUCH lower temperature 52 rather than …

I have a 12" PB as well, and I hooked up a new 20" Aluminum Cinema display I just bought the other day. My fan won't stop spinning at full speed. Needless to say it's loud. I'd be…

Does anyone have a Rev C or Rev D 12" PB hooked up to a 20" ACD? Does the Rev D 12" PB still have trouble? I was thinking about getting the 12" PB and the 20" ACD but if the the …

How do I determine which rev I have?

I have a rev. C 12" PB and a 20" ACD and the fan runs all the time, and the PB is on an icurve. It doesn't bother me a bit, though. I just crank up iTunes. How can anyone give u…

For those wondering, it doesn't appear as though the graphics chipset/controller can be upgraded on the powerbooks: See http://www.everymac.com/systems/appl...expansion.html for m…

no.

I also would be interested in anybody's experience with a Rev D Powerbook 12 and a 20 inch cinema display. I plan to buy one, but if the fan is on all the time...

i have the Rev B 12" as well and get the fan noise as well... but when i could sacrafice performance, i just set energy saver to better battery settings reducing the processor spee…

12" rev. D PB on iLap +17" display = fan runs all the time at probably full speed.

Your heat problem is consistent with 15" powerbook users as well. My 1.25Ghz 15" pb runs at 63.2 degree C all the time with a 20" LCD external display. I am running it in clamshe…

I have a 15" PB with a 20" cinema display and notice the fans come on a little more, but I don't mind. I only hear them if the room is silent, and rarely is with my TV and sound sy…

I had a 12" 1GHz with a 20" ACD -> fan always on and loud I now have a 15" 1.67 GHz with the same 20" ACD -> fan hardly ever on -> very quiet If you have a 12" running wi…

How about running a 12 inch 1.5GHz powerbook with the 20 cinima display with energy savings turned on? Given what IRez said above today, that actually might do the trick.

Ok, so energy savings does not work. How about getting a Targus Notebook Chill Mat - with two fans? That way you might cool the notebook sufficiently. If this worked, you still wou…

I'm curious if the Rev. D 15's have this problem. I'm planning to get a 15" this summer, and a 20" LCD to go with it...If the fans are on all the time I may have to reconsider the…
