This pair of adapter plates that slot together lets you mount 3x 120mm fans to a 420mm AIO Radiator into 3x side by side 120mm or 140mm case fan slots.

This assumes you have 3x 140mm or 120mm fan slots on the case that let you mount the fans so that they are touching. They cannot be spaced out or it won't work. Save money by not buying 3x 140mm fans if you already have 3x 120mm fans. Also, the plates are adapters and 30mm radiator shrouds in one further making the fans work efficiently.

Fits standard 120mm fans and 420mm radiators. Will almost certainly fit unless you have a really strange fan; if in doubt refer to the technical drawing and measure your 120mm fans, radiator, and make certain you can mount 3x 140mm or 3x 120mm fans to your case so that they are touching!

COMES WITH ALL THE SCREWS YOU NEED TO MOUNT PLATES TO RADIATOR AND FANS TO PLATES. IF YOUR RADIATOR DOESN'T TAKE M4 OR #6-32 SCREWS THOUGH YOU WILL NEED YOUR OWN SCREWS.

If you need an adapter for other sizes to other sizes let me know and I can design one for you.

ONLY ONE ADAPTER (2 plates that slot together), TWELVE (12) M5 SELF-TAPPING SCREWS , TWELVE (12) #6-32 SCREWS, AND TWELVE (12) M4 SCREWS INCLUDED.
