My upper fan isn't running during prints anymore, though it can sometimes be jogged by wiggling the flat ribbon cable around near the extruder connection. I'm guessing this means a bad connection at the flat ribbon connector and have ordered new 20-pin sockets. Can I just cut off the end of the flat ribbon cable near the connector and install the new socket or is new ribbon cable also needed?
The upper fan should run always shortly after the printer is powered on, not only when printing.
Yes, it looks like a bad connection of the cable (most probably it is).
You cannot exactly tell if just the connection to the socket is the problem or the cable is broken somewhere, I always change the cable.
Actually for my M200 I have only to change about 50cm on the top end without dismantling the printer because I made a 2 part cabling for mine (wrote about it in another thread).
I would not recommend cutting into the ribbon cable. Here is what you will find.
ohh, i missed that...
The new style (the r&d developed more durable one :ph34r: ) should not be cut of course.
I use the old fashioned standard cables (3M) wich could be cut but I would exchange a complete cable anyway as mentioned before.

Mine is a standard ribbon cable - the kind where you can easily peel off each wire from the bundle. I gather that the one in your picture is a newer type with different female connector. I'll have to try just cutting the cable and see if that works since all I found in Mouser for less than bulk lengths was FEP cable at $8/foot.
Does Octave sell the old style connector? TEquipment sells two types but I've never bought from them before and would rather go with Octave.
Well, I cut off the cable, right at the extruder connector, and pressed on a new connector for <$1 in parts from Mouser. The printer is working like a champ now and all fans are running as they should. Thanks to Julia or whoever it was that posted the Mouser part numbers for the flat ribbon cable connector.

Good to hear, Sorry I did not respond. One of the benefits of having the older cable, it is fixable.

No worries - your picture made it clear that you were referring to a different sort of cable.
