    I have the same problem with the mouse. It does not matter where my hands are and when the pointer takes off and plants it self in the lower left hand courner above the start button. It does not want to leave.  I use the mouse pad and the blue mouse button and it keeps running back to that corner.

Fan problem - on my d820 latitude i called dell about the overheating and constant fan useage. they sent me a new heatsink to put on. when i cracked open the laptop i found out the problem was that the design of the laptop had a fan blowing air across a coil type heat sink to cool the laptop and that coil looked like a dryer lint screen. to fix it, open your laptop to 180 degrees and pop off the plastic part where the power button is. you'll see in the upper right hand corner the copper heat sink and you should be able to clean the lint off.

The fan kicks in because your processors temperature gets above a threshold, and this usually happens when your computer is under heavy load. And when your computer is under heavy load, the computer will most likely be a little slow. Thus the fan speed can only help your computer; you don't want to change anything there.
I'm a little perplexed about your mouse problem, post back with more details.

    Oh thats most likely because when you type the edge of your hand touches the touchpad in the corner, causing the mouse to move to which ever corner your hand is in. Try typing with only your fingers, and see if that fixes it.

    Let me know if that works.

Moving cursor.

well there is a few things that could possibly be happening. if it is a touch pad or a wireless mouse something like a cell phone sitting close enough to them could be causing some interference. the second one is that you could possibly have the mouse keys turned on where you can control the mouse with the keyboard.

Dell Latitude D800 PC - Fan-2-CPU problem

There's a second fan beneath the keyboard, you need to pry open the top panel where the power buttons are, then remove 2 screws for the keyboard to come off. When I did this, I saw the second fan with dust blocking it. I used a vaccum cleaner and my D800 works perfect again. One reason why the top left corner fan runs at full speed is that it reacts to the other fan being disabled, kind of like an emergency detour for the heatsink.
