120mm to 200mm fan conical flanged adapter. Let's you mount a larger 200mm fan in a fan slot that can only fit a 120mm fan. Or vice versa if you want to mount a strong 120mm fan on a 200mm fan slot.

Comes with the 8 screws you'll need; really easy just screw your 200mm fan to the plate and then the plate to the case.

Fits standard 200mm fans and 120mm 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. ASK ME QUESTIONS IF YOU'RE NOT SURE!

Clearance height is if you are replacing a 120mm fan and it was sitting in a well or something and you need to move away from the fan slot to get clearance. It you are changing a 200mm fan, then it doesn't matter just choose the smallest clearance (4mm).

This design smoothly enlarges/shrinks between the 120mm and 200mm sizes and has good plenum volume for optimal airflow.

Unlike other adapters, this design completely fills in the frame around either fan so everything is still sealed airtight afterwards and your fan works as efficiently as possible providing airflow.

IF YOU ARE NOT USING THIS IN INDOOR ELECTRONICS AND INSTEAD USING IT IN SOME OUTSIDE ENCLOSURE, PLEASE CONSIDER TEMPERATURE AND  ASK ME FOR PETG IF YOU EXPECT TEMPS ABOVE 160F.

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

ONLY ONE ADAPTER AND EIGHT (8) SCREWS AND FOUR (4) RUBBER FAN MOUNTS INCLUDED.
