All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.-

I will have a proper heatsink on there soon... for now I welded up the hole in the aluminum plate, replaced the brass up tube with stainless steel, and threaded it into the aluminum plate with thermal grease. I reversed the fan direction and ducted it to blow air across the plate. It works very well. I've run temps up to 240* with retracts, and still no plugging.
I'm not so sure that it will work as well with the brass though, as it is much more thermally conductive. With the stock V2 hot end, the whole thing is a melt zone, including the brass up-tube. If you try to actively cool it, I'd guess you will just end up with a large transition-zone (not fully melted or solid), and a bunch of extra friction.
