Works with HP Z440
The cooler arrived in a well padded package and showed signs of normal wear. After cleaning the old thermal paste off the heat transfer plate, and attaching it to my Z440's motherboard, I found the attached electrical connector is 5 pin vs. the 6 my old heatsink/fan used. The 6th pin is used as a jumper to the 5th, I was able to trim the locating tab off that end and it plugged in fine. The fan is quiet and my processor runs much cooler (and quieter) than it had with just the heatsink and fan.
