cpu fan price???

I am having a AMD cpy.

the stock cpu fan is making a lot of noise and want to replace it.
will I need to replace the heatsink as well?

If just fan can be replaced then
what is the price of it.

and what is the price of it with heat sink??

You only need to replace the fan to get rid of noise.
Good fan’s (quality wise ) cost somewhere between 100 -300 get one of those and if you want to change the stock heat sink also then thats also cheap ranges from 80-200 bux.
