I have one of the new iBook G4s, and I was wondering when the fan turns on. I have watched DVDs, played full screen games, and everything. It gets pretty warm, but not really hot, and I have NEVER felt any air coming out of the back vent. Maybe it's on but on a very low speed so I can't feel or hear it. Does anyone know at what temperature the iBook's fan starts to rev up to where you can easily feel and hear it? Is there any program I can use to test the fan?

Thanks,
Joe

I've had my ibook for a couple of weeks now and only two days ago finally actually heard my fan. I had been playing World of Warcraft for about a hour or so and heard it shoot on. It was sitting on my lap and pretty hot also mind you.

It takes quite a bit for the iBook fans to kick in i found that when doing some CD or DVD ripping they would kick in, also sometimes they will randomly spin up, dont pay too much attention to it,

I had my iBook for a while before I noticed the fan... up to that point, I thought it was convection cooled. :rolleyes:

Huh.. I hear mine (or what I think is a fan) quite frequently. When I'm playing the Sims or other, not very intensive games..

That sound isnt your fans, its the disc drive burning the disc that makes the sound.......The fan is far far quieter than a CD being burnt,

I have the latest iBook 12"...it's not uncommon for the fans to kick off after intensive use. I noticed the fans start spinning loudly when cpu temperature reaches 60 degrees celius.

There is a widget that tells you cpu temperature (i think it's called icpuheat). My cpu temperature is around 50 degreas most of the time. anyone knows what the maximum temp. for the cpu? i.e do i need to the computer a break if temp reaches say 65 degrees?

Its definately fans aswell. I can feel the cool air coming out, and hear them whirring, seperately from the CD drive spinning.

The last time I heard the fans come on on mine was um, ooh, um.....maybe after installing Tiger back in early May when it was indexing and I was putting everything back on. Since then, oh hang on, they came on when i was using Handbrake to rip Arrested Development to H.264 - don't bother, it takes ages...

But under usual use I rarely see temps over 50? maybe 55? if I''ve got a lot of stuff going, extra RAM might've helped too, it sure has made it run better.

I've been sitting at a desk playing music (through external speakers) and surfing the web on a new 12" ibook. The left palm rest got pretty hot; now the fan is on (I had to turn off the music to hear it). The CPU heat widget says 55C (that's 131 F). This is kind of bumming me out-- its not like I'm doing anything intensive. :eek:
