I guess I got very lucky with mine. It is stable at pump powers over 2 watts, but the driver is struggling as I have to have a fan running on it to keep the heat sinked components from overheating. Even the board is getting hot if I don't have the small DC fan running on it all the time. The laser head is staying quite cool, however. I am grateful I got this particular unit as it seems to stay right on 574nm no matter how hard I pump it. I have one additional driver board for it too.
