MPT-7210A Fan Speed Issue

Is the fan speed issue a general problem with these? Or are there units where the problem doesnt occur?

What is the fan speed issue? What is yours doing?

there are several you tubes videos dealing with fan issues on the MPT-7210A. I will see if I can find them
erratic display when an speed is not set to maximum.

I got one to experiment with and replaced the fan in the first 15 minutes with a Noctura 12v one. It's too large to fit inside but a drill and exterior mounting can fix that. It's very quiet even at max speed and moves air better than stock.

I have the issue with the mpt getting erratic readings when setting the fan speed to something else than maximum speed.

I was wondering if this is a general issue or are there units out there that dont got this problem?

Im using it for charging my Onewheel+ from an e-bike batterywhen outside and the fan noise is way too loud on max settings. And im scared that the unstable controller coulddestroy my Onewheel.

Soi just orderd a new 40mm noctuafan(NF-A4x10 FLX) so thecontroller is at least quietwhen running at max speed.

The fan came today and i was pretty impressed of how silent it is. But more important it looks likethe fan speedissue is gone now. I can change the fan speed and the controller stays stable. But the voltage seems slightly off (Set to 58V, shows 58.2V). Is thiseven the right fan?Did i miss something when buyingit?

I have the same issue Machwat - working through the fixes now fingers crossed one works... reflow first, already done the fan mod
