That link doesnt seem to work anymore. Can you please re-link the document? I am getting the same issue and my fan seems to be running fine.

If you happen to find yourself with an HP Z440 and want to max the memory out but can not find the memory cooling solution J2R52AA (Discontinued and very expensive on the second hand market), you'll get these errors:

"517-Memory configuration requires a Memory fan and this fan is not detected." and "520-Memory configuration requires Memory fan(2) and this fan is not detected."

 

You can then trick it to get rid of the error. Just borrow the signal from the rear case fan and connect it to the detection in the memory fan connector.

 

You can then connect any fan you want over the memory using the 12v+ground in the connector as well.

The above pictures (same solution, different angles) are without any extra fans, just to get rid of the error message. You can, of course, put a fan or two in and use the yellow wire from the fan (Providing its a 3 or 4 pin connector on the fan) to connect to the memory fan connector on the motherboard instead. I also printed out the 12v and ground connections if you want to use them.

 

I've been running like this to test for a while and the memory does not get hot enough for me to connect a fan to them. No idea why that error message is for as it seems redundant...

if you look at the hp listed operating temp range for this workstation you will see it covers a wide range and if used in the upper temp range for extended time with all memory slots filled it's possible to have the system/memory exceed the range HP has listed if you do not add the missing fan

 

if the correct fan can not be found or for a reasonable price you should use a quality fan that matches the HP fan specs which is a high pressure fan rather than a high volume fan

 

here's what the HP kit looks like

you need to place the fan so it can cool the area's where the shroud has fans placed make your own fan brackets out of plastic (not metal!!)
