I have a noisy fan (intermittent grinding noise) that I need to replace on my t40 2373. When I search for parts on EBay I have the option of getting a "long" or "short" fan assembly. Is there any way to tell which I need without disassembling the laptop?

Hi again. It sounds to me that the PC is overheating, get a can of compressed air and give short blasts through the air vents and the CPU fan (located underneath the laptop) once your happy that all the dust has been blown out restart the PC and it should be quieter from then on.
The sound you are hearing is probably the fan, This fan has a noisy bearing and will eventually lock up and the fan will stop spinning and therefore the CPU will overheat and shutdown.
The fan needs to be replaced.
Start by taking the machine apart, cleaning the fan, and checking the connection. The failure may be due to debris buildup or a loose connection, and I've also seen fans stop working because a hair has gotten wound in them. If it still doesn't work properly after cleaning, then it will need to be replaced. Here's a link that has breakdown diagrams and instructions, this should help. http://repair4laptop.org/notebook.html
Before getting the fan replaced you may want to try to blow the fan with an air compressed duster. Worked for me. You do not need to take the laptop apart completely. There are 4 screws that holds the keyboard in place, unscrew the 4 and you should be able to pop the keyboard out. Once the keyboard is off you should be able to clean the fan.
