made for an MSI R9 280 - emulates twin frozr fan blade

snap off any remaining fan blades and sand the original gpu fan hub smooth, then press this on over top.

Collar ID - 33.65mm
fan blades max OD - 95.64mm (100mm fan)

Print with supports for fan blades, brim is optional

ensure the top bevel is installed flush with the original hub face, otherwise the balance may be off and cause excess noise

hope this breathes new life into a few GPU's out there!
