Cooling fan for cpu heatsink

I have a fan that is starting to get noisy.  This is the fan that is attached to the liquid cooling heatsink.  The heatsink part number is 657398-002, but I do not know the fan part number.  I have not yet disassembled the heatsink to get the manufacturer info on the fan hub and hoping someone can give me the info before I start tearing things apart.  Right now the fan is pretty quiet and I do not get any errors from the system, but I am worried it might get worse at any time.  I have cats in the house so the interior gets pretty dirty at times.  I have recently cleaned out the interior of the computer using canned compressed air and just brushing and vacuuming.  The computer works fine right now.

Hi,

 

I believe that the heat sink, pump and fan all come as one field replaceable unit (FRU).657398-004

 

Check EBay

 

You can measure the fan and it should be an 80mm four wire model.  You might find something that will work at NewEgg. Your existing fan should have a rpm rating on it so try to match it up to keep the fan curves similar.
