All Macbooks have at least 1 fan. My MBP has two fans.

I use an air compressor at work to blow my computers out. Just disconnect it and blow away shaking the nozzle back and forth. A little water won't hurt the board. Slap it back on and say Merry Christmas.

I guess it was my old PowerBook that didn't have a fan, it's been a while.

It must have gotten miserably hot. My Macbook Pro has been doing a good job at keeping me sterile with even with two fans

I noticed that since I cleaned it out my room has been noticeably cooler today. When I play games however it can actually heat up my entire room.

"The thing is Bob, its not that I'm lazy...its that I just don't care."

I've just completed blowing out the innards of about 500+ computers spread around our school district. It was my second summer project. What a PIA. We do this every couple of years. The dust accumulation inside them is mindblowing. I use a portable vacuum with the long gooseneck hose and different sized fittings. I don't vacuum them out of course I reverse the fittings an simply blown them out. It can go surprisingly fast once you get into the rythm of the operation.

It was about the same as my current MBP, too hot to keep on my lap for very long. Those AL cases can get warm.

Computers and cats have some things in common, both like to ingest hairballs. However, computers don't hack them up on the bedroom floor at 3:00 AM.

Even the newest ones? We had a brand new one (Macbook Pro) come through at my work that I had to set up software on for someone. It had 0 vents of any sort anywhere on the case. So a fan would not do much good with no intake or output for the air!

Mine has a fan, I hear it (them?) when it's running quite a lot of programs at the same time and I place the laptop on a foldable surface like the sitting surface of a sofa. On hard solid surfaces I don't hear them.

They're much quieter fans compared to my wife's Acer laptop, or the desktop PC.

You should see the insides of computers in a SOILS LAB!

You might be hearing the hard drive.....I am 99% sure the newest ones use the casing as a heatsink, and have no actual fans.

Well, at least mine did when I took it apart...



The larger models with a discreet video card have dual fans.
