replace laptop cooling fan

[Bnorikane]

I need to replace HP Envy M4 laptop system fan assembly 698079-001. The p/n from HP is a fan heat sink assembly that includes thermal paste. The fan alone is available for around $15 but the assembly seems to be around $75. Do I need the full assembly? or can I replace the fan. The HP service manual replaces the whole assembly, but at least one web post discussed replacing just the fan.
Thanks for any advice.

Don't know, can the heatpipe (the copper colored thingy) be separated from the fan and re-attached easily, or it is soldered?

I don't know. I'd have to disassemble the whole laptop to find out. I want to have the replacement before tear down.

Hi, some sites sell you only the fan without all the fan assembly, so you can just remove the fan and replace it for your laptop.

Is it easy to just remove the fan from the assembly?

I bought the whole assembly on e-bay, but I'd just as soon leave the existing cpu cooler pasted in place.
