E3D design), runs as soon as you turn on the printer.  At least mine does.

It's wired to 12V output pins on my RAMPS board, and unlike the GCode controlled fan that cools the print, it's not controlled by any board or code logic, so it's just on.

I dont mean the cooling fan that cools the print I mean the one on the side. Is there any way it can be turned off whilst extruder is heating up as it is causing longer heat up times.
thanks!
