TP-Link TX401 fan mount

Active cooling for TP-Link TX401 using a 40mm or 50mm fan mounted on this bracket. print it, screw the fan on the bracket and slide it over the card from the side of the heatsink.

Is it necessary? I don't know, I wanted to eliminate all possible issues on my network and I think the chipset on these cards were designed for high airflow of servers. It got way too hot to the touch.
