Smile CPU/Fan overuse (npviewer.bin, Java).Temps up to 68C

Hi guys, I just installed Ubuntu 10.04 on my Dell Insp. 1545 2.16 GHZ 3GB RAM

I have the following problem that I don't have on Vista.
1. Fan is running almost constantly
2. Cpu temps reaching 69C, stable at 54C
3. Temps spike especially with Java and npviewer.bin (in both FF/CHROME)

Ex. In system monitor, npviewer and Java take up about 90%, and while running, the CPUs are at 1. 80% 2. 90%.

However, even when these processes are killed, basic activity (FF, file browsing etc) cpu% stay near 50/70, and fan stays on.

Question: any suggestions? I heard restricted drivers could cause this problem. Any thoughts?

It looks like it has an Intel GMA 4500MHD integrated graphics card, which is pretty crappy. I hope Ubuntu is using the 'intel' driver and it is configured properly.

Post the output of 'glxinfo | grep direct', it should say yes.

This may help, even tho it's for the previous version:


cpu, fan, java, overheating
