Hey guys. I am having a problem.

1. Problem: My fan is always running (almost always) and CPU temps spike.

2. Situation: I just installed 10.04_64 on a Dell insp 1545 2.16GHZ 3GB RAM
I installed the restricted drivers.

When online I notice that the CPU is being hogged by JAVA or npviewer.bin which then spikes my temps (up to 70C) and keeps the fan on, and my cpus are nearly 100%. As soon as I close the program or kill the process, the temps start to drop. However, my fan is on more than usual anway.

Average CPU temp: 51C
CPU temp with Java/Npviewer: 70

3 Question:A. Are these normal numbers (temps/cpu usage?) 2. Is it normal for the fan to be on most of the time above 45C, and 3. What can I do to rectify this.

Note: i tryed google chrome and this hasnt helped
