What cooling technologies do the TiBook and iBook use?

post #1 of 9
Thread Starter 
I imagine the processor on the 667 G4 gets pretty toasty. What sortt of heat-moving technologies does Apple use to distribute the nenergny? I remember a Dell laptop once had an evaporative copper-tubed funky cooling system. My Dad's 900 MHz Dell is quiet (i.e., no or very quiet fan), so I think it might have that particular tech. A compressor for the refridgeation system must take a lot of power, thoughj./

The G3's and G4's have traditionally not drawn nearly as much power as their Pentium conterparts so fans in Macs are a relatively new thing.

There is a small fan in both the PBG4 and the new iBook, I believe, but they cycle on/off as needed.

Oh, both have heat sinks too, I believe.

My Powerbook G4 regularly runs too hot to have on my lap, especially when plugged in.

Although there is a lot of heat coming from the processor, something in the upper right hand corner, right underneath the powerbutton, seems to be just COOKING. That's where the power plug goes in.

I also believe that in both laptops there is a copper wire running from the heatsink to the rear of the machine, where the heat is distributed (near a vent on both Ti and iBook).

This keep the keyboard/trackpad/palmrests cool. The ibook gets a little warm on the left side of the palrest due to the harddrive being located directly under it.

Cooling technoligy... "what cooling technoligy"

You could cook a turkey inside a iMac...

And get wrist burns on a Ti

iBook isnt much different...

didnt the real cooling technoligy go out along with the floppy drive... <img src="graemlins/bugeye.gif" border="0" alt="[Skeptical]" />

short answer: none/passive convection cooling...

long answer: "insert overt overcomplicated scientific statement here"...

I am fairly sure that if they moved the hard drive to somewhere else than the left palm rest... Not as many people would have a problem with it... they might not even ever notice it...

The Ti uses a liquid pipe cooling scheme, and a fan.

Not sure about the iBook.

I've got a really cool x-ray pic of the Ti Book, but can't access my iDisk from work to serve it.
