Need Computer Fans Replaced, What is the model numbers or part numbers please?

[Tjpost1980]

Please help what is the model number/part number of the CPU Fan and Case Fan of our computer?

Fans seem like making noise worn out?

HP website doesn't have them. I put the serial number of this HP Desktop in this website below and here is the two things that seem close to what I need but not sure if its what's for this specific computer?

This website lists 2 things and not available to order from HP.

644724-001 Common Heatsink, 95W,MT Heat Sink N Compliant/Exempted

This has the CPU Fan and Heatsink, but I only need the CPU Fan not the Heatsink.

646679-001 System Fan, 2500RMP Pirates MT Hardware Kit N

Compliant/Exempted

This is the Case Fan?

Please give links to amazon first choice and then eBay second choice for parts replacement for what I need.

Here is our computer info minus the serial number as this page in this forum says to not give it. Thank you in advance for any help in this matter. Also would need some thermal paste /goo as the old is probably needing replaced on the CPU for the Heatsink.

Fans can be considered as commodities.  The part number changes all the time as fans are improved and manufacturer ramp up and down and change their prices.  NVidia is one of the worse.  If a fan wears out during warrantee they will replace the entire unit and sent the part back to china for a fan refit.  A fan number from the system vendor is probably outdated when the system is sold.

I suggest the following:

Fans are NOT measured from hole to hole:

Use a metric sided ruler and measure the length and thickness.  For example case fan: 120mm x 25mm

Look for number of wires for example 4.  Then look for the current draw and use that as a "close" value.

Make a note of the fan model.  Usually 12xxxyyyzzz where 12 is the voltage.  I have seen a few 5volt ones but they are rare.

Use google to look up the part number.  Very likely a lot of fans will show up and not all the exact part number.  Use the current draw to approximate what is needed and decide if you want ball bearing, sleeve or some fancy liquid bearing.

Once you decide on a particular fan check Amazon, Walmart and eBay and see where it is shipped from.  Frequently Walmart beats Amazon price and Jeff Bezos wont miss a few dollars.
