Summary

I noticed the JHEMCU RuiBet 1-2S LiPo charger runs a bit warm so I designed this fan mod to provide active cooling. You will need a 5v 2507 fan to create this. Print in PETG or PLA

Instructions:

Remove the bottom plate of the JHEMCU charger. This will be discarded and replaced with "Side A".
Mount 2507 fan on to "Side A" using 4x 10mm M2 screws and secure with 4x M2 nuts
Feed the fan power wires through center hole and solder to 5v/gnd pads on the charger's USB port (you will need to trim away some of the outer USB I/O shielding to make it easier to solder directly to the pads)
Mount "Side A" onto JHEMCU charger base using 6x 5mm M2 screws
Mount "Side B" onto "Side A" using 4x 5mm M2 screws

I opted to use a stepdown regulator and run the fan at 3.3v for a more quiet operation
