Upgrading Athlon 64 X2 3800+ CPU

Hello and good morning everyone I have a HP Pavilion Media Center PC a1250n with an Athlon 64 X2 3800 CPU which is a Socket 939 chip and I want to upgrade it to a higher faster Socket 939 CPU and here is the motherboard for my PC (ASUS A8AE-LE). Here are the stats for my current CPU:

CPU/Processor Socket: 939
Supports AMD Athlon64, AMD Sempron and Athlon 64 X2 processors

Front-side bus (FSB) 2000MT/s or 1600MT/s, depending on what the processor supports

I am looking to get the following CPU:

Processor Class: AMD Athlon 64 X2
Processor Socket: AMD® Socket 939
Processor Type: 2
Bus Speed: 1 GHz

So my question is can I upgrade my current CPU (Athlon 64 X2 3800 Socket 939) to an Athlon 64 X2 4800 Socket 939? Please note that according to HP my BIOS is up to date and one other thing do I need to get a new CPU fan?

Thank you guys for all of your help in this matter....
