Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4703652.
Fan duct to suit a Cooler Master NR200 case. Assists with expelling hot air from the GPU via the top front 120mm fan. Useful for GPUs that exhaust air through the backplate eg Nvidia RTX 3000 series, AMD RX 6000 series.
Uses the HDD mounts on the PSU cage. Cage must be mounted in the 'low' position. Although the designs can be adapted for the high position.
Multiple variants: 01 Duct with wings to cover up cables, also directs air from a side mount fan towards the CPU. 02 Duct with wings to cover up cables. 03 Duct only.
May need to drill out existing holes to screw in the HDD 'pegs'. I used a 2mm drill bit and then a 2.5mm or 3mm drill bit to 'debur' the hole.
