Dear People
I recently bought a optus USB wireless broadband, when I log on my
Macbook fan immediately comes on revs around 6200 the whole time I
am connected. Has anyone else had this problem? Also, is ok, I
mean is it doing any damage? Also, any suggestions how to fix would
be greatly appreciated.
Thanks
Janis
Hi,
This won't be the problem here but I thought I'd pass it on any way as
has to do with hot CPU's.
See the whole thing here on cnet >|http://news.cnet.com/8301-13924_3-10396076-64.html?part=rss&subj=news&tag=2547-1_3-0-5

"Firefox has a CPU usage issue and, consequently, can cause
overheating problems in some laptops, particularly ultraportables.
That's what I've found over the last couple of years.
.......
More specifically, here's the behavior as I see it. When I'm accessing
sites with multimedia content such as the CNET front door, Firefox CPU
usage will bounce around between 30 and 60 percent, and sometimes
spike higher (80 percent and above), as indicated by the Mac OS 10.6.2
Activity Monitor.
On the other hand, the Safari CPU usage with the same pages open is
much lower--typically between 2 percent and 10 percent.
...
The fan is usually an audible indicator of CPU usage issues. When I'm
using Firefox and I have tabs open on multimedia-rich sites (which is
par for the course these days), the [MacBook] Air's fan will almost
invariably kick on and stay on until I close the tabs.
