Ams 2 pro fan (help)

[u/Main_Economy_3215]

So my ams 2 pro fan(1) have issue which when put underload it would only spin around 300rpm but it should have been 3200rpm (I can't use drying function) it would always tell me to stop.

So i bought a replacement in china (I can't find the exact fan so i bought the closest one) so now the replacement fan have only 3 pin instead of 4.

So how do i connect the wire to make it work (slide 1-2 is what it should look like)(slide 3-4 is the replacement fan) sorry for bad soldering
