A mod for hotend fan bracket. It helps reduce noise and increase air flow by a magnitude. Need to cut off a piece of metal on the old bracket. I used hand saw to cut the straight section and plier to bend and break the corner section, then use marker to protect the bare metal from rust. It's good enough for me, but the result is very pleased.
There are 2 versions, 1 for original replacement, 1 for modded breakout PCB (This is another project to upgrade this machine with Klipper, I will update later).
I'm able to run the fan at 60% power and very low noise. Now most of the noise comes from the part cooling fan and power supply fan.
