Z420 FRONT fan assembly : Is this the same as any other front fan assembly

HP Recommended

I have a Z420 that needs a front fan assembly and doesn't have one.

 

It's pretty hard to find a reasonably priced used front fan assembly on the used market for some reason. Does anyone know if the front fan assembly from a Z620 or Z820, or from a Z440 (or any other model) is the same?

Below are some of my notes to help you, from the past.  Understand that there are different associated part numbers for the full kits, then just the fan number, then just the black plastic fan holder part number, and the wonderful fact that each of these 3 has both a HP Spares" part number and a HP Assembly part number.  Here's the quotes:

 

"Z420 Front PCI fan & card guide *kit* is comprised of fan holder & fan = 684024-001.  Z420 black plastic fan holder part has AS P/N 604781-003 etched on the plastic which is ***identical*** in shape to the one used on the Z400 (which has AS P/N 604781-001 etched in). These likely also would work perfectly in the xw4600."

 

And:

"Thus, can search for the following numbers and buy the least expensive one. I have also found that eBay sellers sometimes use the fan part number to sell the whole kit so search using that also:

Z400 619579-001 SP P/N (HP calls this "Cooling fan kit with front guard & fan")
604781-001 AS P/N for the black plastic part
xxxxxx-xxx fan

Z420 684024-001 SP P/N (HP calls this "Plastic front card Guide w/fan holder)
604781-003 AS P/N for the black plastic part
>>>>>>> 647113-001 fan (this Nidec fan in Z420 runs at 629 RPM.... excellent)"

 

Or you could consider doing the "ghetto mod" I've posted about here quite recently.......  depends on how handy you are.  Finally, the fans HP chose to be chassis fans were generallly 92x25 mm PWM fans with a 4-pin plug, with orientation ridges down the sides but not one in the middle area.  You can easily find such fans from HP on eBay but the Nidec one above for the ZX20 workstations gives a nice quitet result.
