I replaced the fans in both my Ego ch2100 chargers and my ch3200 charger with this aftermarket fan: https://www.amazon.com/dp/B07VVGHTSR?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 It has dual ball bearings instead of the cheap sleeve bearing in the stock fans which means much longer lifespan, It also exceeds the specs for the stock fans in both of those chargers for CFM & Static Pressure which means better cooling (which means longer charger life too). The rpm is a bit higher than the stock fan so the fan is a bit louder than a new stock fan, but not much (I charge my batteries in the garage so it doesn't matter anyway). It also has an IP67 rating, so it's going to be much less susceptible to moisture and garage dust and dirt for longer life as well. This fan is an upgrade for both of those chargers. (this fan will not work for the higher powered Ego chargers). You must be careful when using an aftermarket fan to find one that has a similar current draw as the stock one because the ego charger's logic constantly monitors the current and if it drops below a certain level (I've read it's somewhere around 0.08A) the charger will assume the fan is not working and it will throw a fault code and shut down. This fan has a slightly lower current draw (0.12A vs 0.16A for the stock model), but everything works fine. If you go with this fan, you must be careful of the pinout in the connector and make sure you match it to the stock fan's connector. I had to swap the order of the 12v and ground wire, the tach wire was correct. I'm sure there are other fans out there that will work as well and maybe you can find one that has the correct specs, connector and pinout (but it won't be easy to find!)
