There has been a update in the geometry of the main control board heatsink. The default heatsink used in the NOVA DVR3000 main control board has a tapered side to compensate the steps found inside the headstock casting. This taper has been removed on the modern control board desgin as the main control boards are slightly smaller. Image below shows the comparison between the old and new heatsink designs.

New Heatsink Design


The old heatsink design is now obsolete and no longer available. The new heatsink desgin can be fitted into the NOVA DVR3000 headstock without any adjustments (such as grinding etc.) however, the location of the ground cable connection must be relocated. 


Detailed instructions on how to take out and installing the main board is shown in the PDF documents attached to this article.
