I have this Dell laptop. I'm new to these, I've never worked on a laptop before. There are two fans in this system. If you're facing the monitor typing: A CPU fan far left upper corner, and what I think is the GPU fan far right upper corner. The fan in the far right isn't running. I8kfanGUI, tells me that both fans are running, but when I get the temp readings they show as below:

Temp via I8kfanGUI

CPU: 32 C
GPU: 61 C
Memory: 38 C
Chipset: 41 C
Harddrive: 38C

Everything else is working fine, as of right now but I feel no air flow from the bottom, top or side vent. I turned the machine on it's side, and sure enough, even at 63 C, that fan for the GPU wasn't running. The left side of the laptop keyboard is cool, the right side is warm obviously.

I've always kept this laptop propped at about a 2 inch angle in the rear, allowing it to breath a little easier, since I knew the ATI cards were prone to burning out in this model without proper cooling and circulation. Perhaps I need to invest in an external cooling pack after I repair this fan.

Can anyone give me general instructions or ideas on how to get this GPU secondary fan to work correctly? I picked up a few ideas while reading prior to posting these questions, cleaning out dust etc. If you can answer any of the questions below, that would be very helpful.

Questions:

  1. If I need to buy compressed air, what type of store carries it?

    Note: It's a Dell E1705 Laptop:

  2. If it's the GPU fan, can it be individually replaced or must the ATI Radeon card itself be replaced? It's a 256MB ATI MOBILITY RADEON X 1400 HyperMemory card. Where can I buy the individual fan or the entire unit for a good price if I end up needing that?
  3. I will buy the external cooler either way. Does anyone have a good suggestion for the type/manufacturer, and the place to buy it? I can't spend big bucks, $50. I should also buy a stand that goes under the laptop that gives it more circulation.
  4. Finally, if I have to take it apart myself, how can I do that -- are their diagrams or instructions available that anyone can link me to?
 
I found what I was looking for. For anyone who needs to replace the fans or to clean the fans of their Dell Inspiron E1705 or 9400, go to this link below:

This shows you how to also remove the video card if you wish to replace it.
 
Where can I get the screw drivers, electro-static discharge protective gloves, armbands, and the compressed air? Also, where can I get the secondary fan?
 
Check for it on newegg, amazon, etc...
You can pickup compressed air and the screw driver at a local hardware store
or failmart (walmart).
