What I found was a nifty FREEWARE utility called Speedfan, which allows you control over your fan and more importantly, gives you a temperature reading of your CPU! Awesome! While I am not attempting to change any of the fan settings, I was trying to see how hot my computer was. Typically your computer should be running around 45 C to 55C for an optimal temperature, but the cooler your computer is the happier it will be for most purposes. When I ran Speedfan it told me what I already suspected. That my laptop was overheating. This disturbed and frightened me, because I have not money to get a new computer should this one break down on me. (I can't even keep my truck on the road!). My CPU was running at 72C!!! Here is breakdown of laptop temperatures.
25 C to 35 C You are operating your laptop in a freezer or the arctic, no problems, make sure your LCD screen remains operational.
35 C to 45 C Your laptop is brand new. And you are not heating your apartment or house because you are too cheap. Its probably for the best because of high energy costs these days.
45 C to 55C This is your 'normal' operating temperature. Keep your eye on it, but all is well. For now.
55 C to 65 C You are a contractor working in a desert somewhere. Your lappy is running a little hot, but nothing to be too worried about. You might want to take your laptop from your actual lap as the added heat may cause temporary sterility. You might also want to switch to boxer briefs for the same reason.
65 C to 75 C Its too hot. You should be a little alarmed now. Your laptop has now replaced your space heater as the major heating source in your apartment.
75 C to 85 C This is dangerously hot. Your coffee is best kept warm placed close to your lappy. Possible issues: battery problems, stogged fan, overclocking or your CPU is working too hard.
85 C to 95 C Your laptop has shut itself down and you are at Circuit City or Best Buy looking for a new one. If it's still working, the fumes from melting plastic are making you delerious. There is a pretty decent chance your computer will burn your house down.
95 C to 105 C Your house or apartment block is smoldering rubble and a lot of people are upset with you.
105 C and above If your lappy has lasted this long and is this hot it will actually ignite the oxygen and hydrogen particles around it creating a 'mini-sun' that will burn anyting within a 50 meter radius.
So anyway, back to my computer. See the problem with it was that I had not done much maintenance. (Read: I hadn't done ANY maintenance) I hadn't shaken the dust from it, got rid of the ad- and spy-ware, and defragged it.
I ran Spybot: Search and Destroy and CCleaner. Then I defragged it with a pretty decent utility from Auslogic called Disk Defrag that's not supposed to crash your computer.
It took a day but after I was finished...woohoo! My lappy was running at a respectable 55 C/60 C!
The next step was to open her up and get the crud out.
So here is the super ultra Model 354a Power Fan opening. Actually I don't know what it is, it has something to do with a 'heatsink'. Anyway, to clean it properly I allegedly had to open up part of my laptop.

Which is what I am doing here...I basically tore the panel off. It was attached with little tabs.

Once that panel was safely discarded I needed to remove the keypad to see what else was under it. I needed to get to the fan and heatsink so I could use the bottled air and clean it out. There was two little screws just above the F5 and F10 keys. I took them out...

...and VOILA! The keyboard was off and I could see my heatsink and fan contraption. I was told that there may be more heatsinks placed in different parts, but for my purpose, this was good enough.

Then I gave it all a blast with the canned air, making sure to blow the dust outward, and also making sure not to turn the fan too fast. I also made sure that I did not blow those two tiny little screws that held my keyboard in place off the table where I was working; so I wouldn't have to crawl around on the floor looking for the damnable things.

I ran Speedfan once again, and now my CPU temperature is a normal 45 C to 55 C. I am happy, my computer is happy and ad driven web content providers are happy.
