Orange Pi Plus doesn't have support to control a PWM fan. Moreover, standard PC fan requires 12V, while the Orange Pi Plus is powered by a 5V power supply.
I added an heatsink to my Orange Pi Plus, and I'm using a standard 3-Pin Temperature-controlled fan with the thermistor inserted in the heatsink, powered by an external 12V power supply.
This is my FAN, but you don't need a 120 fan. I used it because I already had it and I have to cool other items near the Orange PI Plus.

There is no circuit. The fan is already "Temperature-controlled", you can search for images in google (arctic F12 TC). An example


It exists in three dimensions 80x80, 92x92 and 120x120. Here the official page
http://www.arctic.ac/de_en/products/cooling/case-fan.html
See the TC models.
A part from Arctic, there are other models of Temperature-controlled fans.
For the power supply, it should be very difficult to find a 12V power supply with a connector that fits the fan. You have to cut out the original connector and solder a two pin connector. Moreover, you have to check the fan specs for the current required, I have a 12V 1A power supply.
Specs of the arctic F12 TC (max current 0.24A, in my opinion you should use at least a 12V 500mA power supply)

I have some old 12V 40x40x10 fans, and I tried to connect them to 5V. Many of them works spinning very slow, but if you are using a heat sink, it should be enough, with the advantage that it is very silent.
Later I'll try to post some photos.
