Fan causes thermal runaway
When I print sometimes the fan kicks on at 255 speed and cools the nozzle too much and it shuts down the print with a thermal runaway. Is it really that hard for the controller to remember where the print left off so that we can save the print when we get any kind of error?

Try adjusting the direction the fan shroud points. And add a silicon sock to the heater block. Then perform a PID calibration so the firmware knows how the new configuration behaves.
Also - a PID without the sock sometimes helps prevent this feedback loop.

For me fan doing little bit of noise, how did you solve this ?
RE: Fan causes thermal runaway
I had a problem with prints lifting (PLA) and just simply resliced code with Fan perimeters unchecked ( No Auto Fan/Fan always on), and then used either NO fan during print or manually selected during print - not a solution, but a work around until you find proper fan settings for a particular print...this might help for the thermal runaway.....
