Highlights

S duct for standard 80mm computer fans. Redirects airflow around an immediate obstacle that's directly in front of the fan. Comes in custom heights (thickness of duct) and custom total lengths.

To purchase the right one first measure your fan size (total width) and make sure it's 80mm. Then, measure from the further edge of the fan to where you want the duct to end - that's total length (see technical drawing). Then, measure from the fan directly forward in the (usual) airflow direction until you hit the obstacle you need to get around - this is the height.

If you want the duct in a color other than black OR if you are going to be using this duct in an outdoors enclosure in direct sunlight, you probably want to do the green PETG or black ASA material which can withstand up to 180F (ASA 220F). Please message me or leave a message on checkout in that case.

If you have some other fan size or need another height or want another color, just message me and I can design something to work for you.

COMES ONLY AS SHOWN - ONE (1) FAN DUCT AND 4 M5 SELF TAPPING SCREWS

It works really well for builds that need to get air from other parts of the case it also improves cooling in those hard spots as well
