Upgradeing hp m8067c

[aero1234]

I have an HP m8067c Media Center PC that has a cooling fan that has just died.

I'd like to replace the cooling fan, but am not sure what to replace it with?

As well, if I'm replacing the cooling fan, should I consider upgrading the CPU while I am doing it?  The m8067c has an Intel LGA775 Core2 Duo and I've already upgraded the memory to 4 Gigabytes. 

Here's my questions:

1) What cooling fan do I buy to replace my current broken one?

2) What kind of CPU can I upgrade to with my existing motherboard and socket?

3) Aside from pulling out the old CPU and putting in a new one, installing heat-sink over the top and then installing a new cooling fan, what else do I need to do in order to make a new CPU work?  (BIOS upgrade, etc)

Thanks VERY much for your help--you guys seem like you actually know what you are doing with HP products, not just doling out free advice generically to a million systems (like so many boards out there).  I appreciate your expertise and your opinions.

Aero, since there are no specs for the fan, I am guessing that it is an 80mm (approx. 3.149").  You can measure it to make certain.  The main thing is to assure that the connector will fit properly.  Buying a fan locally may be your best bet.

Here is the 'Motherboard Specifications' page for your computer.  It lists the CPU's that are compatible with your motherboard.  If you stay with the HP suggested CPU's, you will not have to do a BIOS update.  HP will not support any CPU other than the ones they list.

One thing that you didn't mention in your list of to do's is adding 'thermal compound' to the CPU before adding the HS/Fan.
