Check the listing for details. 280mm Radiator +3x 120mm Fans to 3x 120mm Fan Slots Mounting Bracket Adapter Mod. Condition: New. Listed at 22.99 USD. This pair of adapter plates that slot together lets you mount 3x 120mm fans to a 280mm AIO Radiator, assuming you have 3x side-by-side touching 120mm case fan slots on the case. Save money by not buying a larger radiator and get better airflow with less noise since you can now use larger fans against the 280mm radiator. Also, the adapter plates provide a 30mm radiator shroud or plenum further making the fans work efficiently. Fits standard 120mm fans and 280mm radiators. Will almost certainly fit unless you have a really strange fan; if in doubt refer to the technical drawing and measure your 140mm fans, radiator, and make certain you can mount 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 , EIGHT (8) M4 SCREWS, AND EIGHT (8) #6-32 SCREWS INCLUDED.
