Good going. Running it on low speed makes it noiseless.

Sorry I didn't check the forum for a long time.

The fan is simple DC fan 5V purchased from Aliexpress. Yes it is 2 wire.

And sorry for posting here as at that time I was using Openelec. I have recently switched to Libreelec and will shortly implement this too.

For PWM you can check here

here is my script that is working for almost a year. I am not taking any credit and dont consider myself a programmer. Studied a few scripts and got help from python reference tutorial and GPIO examples at sourceforge. This one works and fan speed varies with temperature. Starts at 60 degree and full speed at 78.

shared just in case someone needs it. uses PWM for speed control. I am using a transistor for supplying power to DC fan and GPIO triggers that transistor.fanspeed.py.txt
