Check the listing for details. 50mm to 60mm Fan Adapter Converter change mounting PC Modding Flat Custom Mod. Condition: New. Listed at 8.77 USD. 50mm to 60mm fan adapter plate. Let's you mount a 20mm fan in a fan slot that can only fit a 60mm fan. Comes with the 8 screws you'll need; really easy just screw your 50mm fan to the plate and then the plate to the case. Fits standard 50mm fans and 60mm slots. Will almost certainly fit unless you have a really strange fan; if in doubt refer to the technical drawing and measure your fan & fan slot. Unlike other adapters, this design completely fills in the frame around the smaller 50mm fan so the case is still sealed to air afterwards and your fan works as efficiently as possible providing airflow. If you need an adapter for other sizes to other sizes let me know and I can design one for you. Note, picture of white adapter in use in the case are of the 92mm to 120mm version - picture just to show you what the white looks like ONLY ONE ADAPTER AND EIGHT (8) SCREWS INCLUDED.
