If you now start up gkrell, you can see that cpu temperature starts to rise quite rapidly to the high 50s, and the fan gets very loud indeed. I don't know how far it would go, because one of us closes the browser fairly soon when this happens, and eventually the temperature falls to below 50.
That might well be a normal operating temperature for that cpu under load, if the noise is annoying then replace it with a better and more efficient cooler (perhaps look at http://www.quietpc.com )
It does do it when rendering some pdfs. Particularly, it did it with a graphics intensive pdf of some sort.
Is it just the cpu is being taxed sometimes and never was before? The other option is that it might be some flash content in a banner or advert on the page. I've encountered flash content before that will immediately peg the cpu to 100% and the only way to return the machine to a usable state is to close that tab in the browser. The cause for this is that people writing flash banner ads don't really care about user experience so they do it quickly and don't test it (I presume) I recall my dad asking me for help on his dialup as he couldn't check out on some web-shop, it turned out that the page was loading a flash advert before the checkout screen and the advert downloaded 2MB of data which obviously took a few minutes and caused the page to timeout while stuffing the cpu to 100%.
