I've actually done this. I used the pictures here: http://www.irisvista.com/tech/laptops/ToshibaA45/Satellite-A45-remove-hinges-1.htm as a guide.

I did Step 2 but only removed 4 screws.

In Step 4, they forget to mention that you have to move a lever to release the CPU.

You want to be careful lifting it out. It's actually two pieces. The chip and the heatsink are stuck together with thermal grease. If you don't break the grease seal, you'll be able to keep it in one piece so that you can see the dust as shown in Step 5. Then you can put it back together.

If that chip unsticks from the sink, you'll probably have to regrease so that the grease will conduct heat like it's supposed to.

HOWEVER, it requires the Atheros Client Utility v2.4.2.18, to be installed. If it isn't installed on the laptop, this utility needs to be installed first. Then the Driver above.

The cooling fan is not working


THe shutting down is your laptop's thermal protection. It is trying to keep the CPU from being destroyed.  You should stop using it until you fix it, or you will destroy it.
The fans are not hard to replace and toshiba disassembly is fairly straight forward. Just get your #1 and #2 phillips head screw drivers and pay attention to how you take it apart.
Call Toshiba and order replacement fans for your laptop as they will not set you back very much.

Manual


There's only one guide that I could find for the A45. It should help, depending on how far you have the machine torn down.
