Hi, I can get the fans to pass the test if i remove the shroud. Do you put the shroud back on after the pass test ?

Yes, the shroud is important to directing the cooling air in the right direction. I've been doing this when needed for a while. It is a pain. 

I did update the firmware to a recent beta which helped with passing the test with the standard shrouds on, at the recommendation of prusa support.

I'm getting errors during print now that the fans aren't working, when visually, verifiably they are. So I disabled the check.
