I'm working on a dual head setup on the Ultimaker2, and want to use 2 heads, so also 2x side fans (4) and 2x back fan.

If I just put them in parallel to the existing fans, will the board be able to take the double power load ? or do I need to play safe and power them separately (is there a better place to get the power from the board?)

here's what I'm working on;

    On my Umo+ (um2 board) and after breaking some stuff I can assure you there's no problem. On fans you can put 500milliamps max (400 to be safe). I run x2 24v fans in parallel. On the paper um2 has enoguh power for dual heads and all that. But it's really right. The heads uses 20w instead of 40w umo+ so for me I had to use a new power supply.

    You could also use the power from the leds to have a different fan power setup for the second head. Just in case the second head material needs different fan power and this eay you can turn the fans on/off for each head

    You could also rotate the fans so they stay stationary on the magnetic camp center. The space shouldn't be a problem since you are already using some for the second head mount

    yep, I thought of this as well, would be nice... on the other hand foehnsturms experience is that its better to keep the heads cooled while parked, to avoid temperature swings. Think I'll start by just adding a copy of the current setup.

    thanks for the confirmation that I can safely run the extra fans in parallel
