Fan cooler?

[master92]

Greetings brothers, again I here jajajajaja, recently one of the fans of my Antminer S4 reached its end, gave everything he could give, on the support page show several models that can replace said fan, acquired this model

Delta TFC1212DE



Now the problem I have is that the miner does not recognize me as a fan, that is, he shows his speed at 0, is there any way he can recognize it?

Thanks in advance!

If I remember right, the Delta TFC1212DE uses reversed PWM signal.

In short, that is why it does not work with the Antminer S4 controller.

I think the easiest way for you would be to have another fan model.

In that guide, the cooling fan manufactured by Sanyo is a good one.

It is does not have reversed PWM signal.

I used to have that Sanyo as a cooling fan for my Avalon 6.0 back in the days I had that miner.

Very good quality fan.

Very grateful for your answer brother !!! How unfortunate that he bought the one that was not, I should ask before doing it ...
