</div>Most people like it when the fan is off or operates at low speed. It<br>
saves battery life.<br>

</div>Opening applications, backups and file transfers do not take CPU. They<br>
take disk and/or network bandwidth and should not be much effort for<br>
anything like a T61.<br>
<br>
Computing package dependencies, batch photo processing, audio or video<br>
transcoding and many games place high demands on a CPU.<br>
<br>
I recently tried powertop and found it to be very helpful in reducing<br>
processor use.<br>
