I've got a HP Pavillion A350N the heat sink/fan doesn't fit flush on top of the CPU.  The cause is that one of the arms that clamps it down is broke.  Can anyone tell me the exact replacement part for this?  Do I have to replace the entire unit?

Its an intel P4 (i beleive 2.8 ghz) with HT.
HP's website lists it as socket: mPGA478

Hi Lakefront,

Any PGA478 cooler should fit your processor, that's the whole idea of the socket. Just go to your local computershop and they'll be able to advice you.
In case you want a quiet cooler that also looks neat, you might want to check out these:

To replace that broken arm, do I need to replace the heatsink AND Fan?  Or just the fan? or what part exactly?  I don't know anything about this.  Where is a good place to order it online?  And what exactly do I need to order?  Thanks!

I think you'll have a very hard time finding only the arm for sale without a full heatsink and fan. You might just as your local vendor as I don't know any online stores that'll have those.
A full heatsink/fan combination isn't that expensive though.

The heatsink and the fan (it's usually just one part)
You'll need to remove and replace the thermal paste which will be on the processor, make sure to use only a tiny bit of it, and from a good quality (don't use stickers as they'll make your CPU run hotter)

On the main site of Zalman => http://www.zalmantech.com/
In the lower left you'll find a link to "How to install" See some of those and you'll see what you need to do with different coolers. If you get yourself a cooler some manual will also be included stating almost the same, it isn't hard at all to do.

Most of the time the paste is separate, as you're not sure what you need, the best advice I can give you is go to your local computershop as they will know exactly what you need.
Any PGA478 will do for your system as they are all made for exactly your processor and your socket.
You can find cheap ones wich will do fine, but probably make a lot of noise and maybe let your CPU run a little hot (not close to overheating, but they're sure not good enough if you plan on overclocking your system)
You can find expensive ones which will be very quiet, or cool very good so your CPU will be very happy all the time.
Somewhere in between is probably the kind of cooler you might want to install.

Personally I have the CNPS6500B-Cu (http://www.zalman.co.kr/eng/product/view.asp?idx=39&code=009) and it suits me well, it's a bit big though, so you'll have to see if it'll fit in your computer, I have heard that with some systems it's so big that one of the memmory slot's can't be used anymore.

There just isn't such a thing as: "This cooler is what you need" it all depends on what you want.
