Yes, it working but im talking about the noise. Not exactly from fan when it cooling. But the noise when the fan controlled by PWM at low values ​​0-38 does not rotate but makes a sound from the pulse frequency of the PWM.

It work good but sound on 1-244 is annoying.

Hi, I already have changed transistor, but now when I change on lcd from 1-244 I can hear squeaks from fan.
And when I set 255 it stops.If connect fan to the led connector on driver board Im getting the same squeaks. What else could I damage on my board?

I have already found broken transistor. It was Q2 transistor under E0 driver. And it totally broken, it obviously that I should change.
In my town I found similar transistor (AO3400
N-ch; 30V; 5.8A; 1.4W; 0.028 Ohm). Will it work or I have to buy A6sHB?

OK, but I have gt2560 v3.0 and it is not in the same place as in the picture from the link. Also trying to find the way to resolve that problem I met the user a30 with the same problem and he asked me to ask you where on his board there is a transistor which is responsible for the PWM fan. So can yo...

OK... A few more question. Just for confidence. 1)Adapter board it is the board near hotend? 2) Im correctly pointed pwm on board on the picture and pin of it i should measure. 3)As I already understand I have burned the only pwm supported port near hotend. But as I can see in marlin fan connectors ...

that connector pins I need. Air blower isnt working.

I have burned my model fan connect(which controlled by software from 0-255). But there is still a lot of free connector.And I want to know which numbers i should type in software. I use only one connector of my radiator fans and which which pin is responsible for them and if they support pwm. In mar...

What the difference between new and old version?
Its only new version of gt2560 or other new hardware?
