Summary I noticed that the Micro-Swiss Hot End version of the fan duct for this fang blocks the sides of the heat sink almost entirely, so I opened a vent in the side to allow for more airflow through the fins and better cooling. There are two versions, one the original height, but with a vent cut into each side, and the other with a simple plane cut to make the whole thing shorter. I'm running the vented version on my rig, and haven't tried the other. Not sure which will work better. The rest of the fang is here: https://www.thingiverse.com/th...

Like many of my designs, this one is available for free on Thingiverse, or you can support my work by downloading it here.
