Nope, my Ultimaker 2 Go machines have different PCB revisions, 2.1.1 and 2.1.4.
With 2.1.1 electronics, the fan is always on.
Are the schematics available?
Edited by Guest
Well then that may be your problem. I'm not sure what version board came with the feature but you may be stuck with it always on.
If my memory isn't failing me, 2.1.1 is the "old" version without fan control. The new one has only been around for a very short while (since April(ish), I don't have a firm date or serial number range).
Doesn't look like schematics for the newest board is available yet:

Here it is. The new UltiMaker S7
MariMakes posted a topic in Official news,
The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

Cura 5.3 Alpha With New Tree Support 🎄
MariMakes posted a topic in Ultimaker Cura,
Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.-

The UM2go's have a new circuit board that allows the fan to be controlled. eg on and off. As older printers didn't have this option it wasn't included in the firmware.
So FW 15.02 didn't have this option so the fan turns on as soon as the printer is switched on.
the feature was included in the new firmware 15.04go so that's why you see one turn on at 40deg.
the 3rd printer may have an issue. upgrade all printers to the new firmware and see if it resolves the issue of with the one not going. If it still doesn't work then check the wiring. You need this to work or you will end up having feeding issues and it will shorten the life of the PTFE coupler.
Make sure the solder joints on the fan are still connected, then make sure the plug is connected properly with no loose pins. If all ok the check the main board under the machine to see if it has a loose wire or broken solder joint.
