hi
Thanks for to many and shoot up answer
I would not like to open the fan there
I fear have to destroy him by it
Unfortunately, the manufacturer Nidec spends to this model also no information
The manufacturer publishes only information about the state kind model
I have had a look at the fan sometimes closer and, besides, a small label still found with data on it .
Maybe this can also help?
I have already seen many fans models.
The highest Pin connections had been 4 Pins.
Adaptors of 3 Pin on 4 Pin are also known to me.
They can be all put on with the standard power on 2 Pin Easily pursue. So + and - DC
6 Pin model here in the thread is new to me and, hence, I am surprised why it with 12 volts DC put on the standard Wire on red (+) and black (-) does not work.
