E3D V6 30mm_to_60mm Fan reduce/adapter

thingiverse

The H50 mount adapters that are readily available will reduce a 120mm radiator fan to 92x140x25 size for a H80i, H90, or other similar configurations using the push-pin mounting bracket of this adapter. This configuration has enough clearance with most popular mid tower cases and some full towers, provided that any screws that go into a radiator fan mounting area do not get in the way. This approach will work only with those radiators that use four-pin Molex for 12V DC to run them since these fans don't use SATA connectors and can therefore connect to any of those power leads or be plugged right onto any Molex adapter. The provided link includes a picture and further detailed instructions on how you would modify the H50 mount adapter. Please ensure that proper attention is given during assembly as a very fine screw needs to go all the way through a piece to make this modification successful
