Watch your mac

Heat and noise are problems for all the laptops I used, either big or small screen, slow or fast cpu. But I never spend time(maybe I don't :) to figure them out. For example, you'll see lots of ppl talking about everyday that their cpu hits 100% for whatever reason and fans get crazy for no reason, blabla.

Anyway, with my new mac, I am chilled, so I want it to feel the same. So first of all, I really want to find a way to monitor it on realtime, 'cause wherever something happens it might be too late to look at.

Here we go. I used two utilities. One of them is Activity Monitor came with OSX, very powerful and useful, I press command-5 to set CPU USAGE to float vertically at the left-bottom corner of the desktop and also ask the dock to show CPU HISTROY. This way I'm positive of what's really going on with my cpu at any time. Yes, that's right, this is the PLAN.

Second utility I downloaded online is called Temperature Monitor, hehe, with it, you can monitor cpu, hard drive, battery temperature. With the help of temperature, not only I get better picture of the relationship of the temperature and cpu usage, but also can I find way to deal with things promptly.

After I get used to the normal behavier of these two utility while doing common work ex. open close folder, open a couple of applications, etc. I start to surf the web. Here's where the monster comes.

I still can't believe this monster is tied to some website I regularly surf. But I am positive that they're the ones , at lease in my Mac. Whenever I surf these sites, the cpu usage will hit 100 and won't come back to below 5 after loaded (This is strange, 'cause you want cpu to hit 100 whenever it doing things but you don't want this last long, because the heat is mostly due to the cpu usage and the time it spent on staying on that usage, this is dueto the heat takes time to conduct and difuse away through air which is highly non-conductive.) This is long discussion, in short, these website sucks, most of them have flash, movies, tons of ads.

Here're two links, one of them is popular chinese site, www.sina.com.cn, and this one is the killer. Here's one english one, http://www.appleinsider.com, but this one mantains cpu usage around 40%, not good either but not too killer. I can't remember others, 'cause usually whenever I notice this from cpu history or temperature hit over 50C, I close them immediatly before I can record the sitename.

The above test is made using various browser, firefox 1.0.4, opera, camino, safari, IE on mac. They all have same behavier on these sites, but some are better than the other one.

I'd like to hear any comments.
