Hi new here, is it possible to control 5 48v pwm fan with 2 of the fan there uses irlz44n mosfet and it's job is to power on and off the 2 fan, and 3 fans job is control the fan in series like low medium hogh
Are these two wire three wire or four wire fans?
Which Arduino do you have?
How much current do the fans need?
Do you datasheets for the fans?

Welcome! From your question I highly recommend you get a copy of the Arduino Cookbook and go through it cover to cover and try any of the projects that are interesting. You will probably find your project or something similar in there with code, circuit info etc.
To answer your question Yes. I would not use that MOSFET but get one with a higher voltage rating. A 55V rating is close especially when there are inductive loads.

These are four wire fan
And we use arduino mega for it
I current don't know how much current does our fan even we can't find it's data sheet.
But i know that the fan is 0.75 ampere and 48v
It consumes about 40-50watt at maximum power.
We already tried irlz44n, it works but when we try to control the pwm fans with no mosfet it doesn't work as we intended.
The output would be like in sync, but the difference is we can turn on and off the fan with the mosfet but we can't control the pwm fans without the mosfet.
Thank you for the reply.
Can you recommend a mosfet within that rating? We use one mosfet per one fan. Currently we only use 2 mosfet because we only need to turn on and off the 2 fans, but we need to control the pwm of the 3 fans.
Thankyou for the reply.
Sorry I cannot recommend one as I do not know what resources etc are available but put "MOSFET 100v 10A" in your DuckDuckGo search bar and it will give you a lot of parts to chose from. You can place the two fans in parallel for on and off and again with the remaining three if they are running concurrently.
What PWM frequency did you use?
