The only reference I find is http://h10032.www1.hp.com/ctg/Manual/c00212209.pdf
There's only one road out on this trip. Disassemble the laptop and measure the dimensions and take note of the fan's voltage and possibly the current.
The head over to DIGIKEY.COM jameco.com 1coolpc.com and see if you can dredge up a fan.
You may have to cut off the old fans connection and solder it back to the new fan.

I have a laptop HP PAVILION ZX5180us and one of it's cooling fans is not working. I call HP for the replacement fan (part #350232-001) and they no longer have it. It's a 3 pin fan but I don't know what size. There's a lot of companies that sell aftermarket fans but I need to know the size. Does anyone know what size fan I need for my machine?
