I think Rigol is seriously mishandling this design issue so far and they will be forced to update their board again after your review Dave. Seriously your videos are so well known by the community (including Rigol themselves posting your reviews on their website), that there's no way in the Universe that they will escape a proper thermal management of this part now... They will have to handle so many returns, so many complaints (with mysteriously broken warranty stickers), so many questions to support... It's a direct path to a shameful failure. It's true these supplies don't sell like Iphones volume-wise, but considering that Rigol wanted to set a new market standard with this supply, they won't escape this. So in a certain way, your video is going to cost them the money they avoided spending in the first place... There may be some justice in this world after all...
