New Compatible CPU Cooling Fan for Lenovo Thinkpad T440S T450S 04X0445 04X1850 UDQFWYR02BCM 5pin 4line Laptop DC5V 0.5A (NOTE:for FIT UMA FAN)

So quiet I thought it wasn't working at first.

The fan had two issues. First, the body was 3d printed. That should be fine, but they tried to 3d print the mounting holes. One hole was too big to accept the screw and the other was just a tiny dimple. Second, the ground screw failed and so I grounded it against a bare spot on the heat sink.I guess not bad for the money. It resurrected an otherwise not functional laptop that I will use to drive a CNC machine.

Title says T440S, but it actually does not fit. this is the second time I but a fan that is advertised for T440S, which is actually too big for it

There is too much material here on the mounting plate for it to fit into where the UDQFWYR02BCM goes on the lenovo I have.
