This pair of adapter plates let you use 180mm fans with your 280mm AIO Radiator with either 2x side by side 180mm case fan slots OR 2x side by side 140mm case fan slots.

These 28mm tall adapter plates smoothly reduce the larger 180mm fan airflow circle to the 140mm size of the 280mm AIO radiator and sandwich between your radiator and fans with the fans mounted to the case or the radiator mounted to the case.

Comes with the screws you'll need; really easy just screw the radiator to the plates with the #6-32 or M4 philips screws using the underneath recessed holes. Then, use the M5 self-tapping screws to attach the adapter plates to the fans and then place the adapters and radiator assemblage to your case fan slots and screw the fans to the case from the outside of the case using the M5 self-tapping fan screws.

Supports center hole spacing on the 280mm radiator between 15mm and 19mm for maximum compatibility. It's usually 15mm or 16mm.

Your radiator/fans will sit another 28mm inwards in the case after this - please make sure you have clearance.

Also if your radiator holes are M3 or something instead of the standard #6-32 or M4 (haven't seen it though) you will need your own screws.

Fits standard 180mm fans, 280mm radiators, and 180mm/140mm slots. Will almost certainly fit unless you have a really strange 180mm fan; if in doubt refer to the technical drawing and measure your 180mm fans, radiator, and fan slot.

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) AND TWENTY-FOUR (24) SCREWS INCLUDED.
