I dunno how hot is to hot... but I believe the hotter the driver gets, the less efficient it is. If keep a fan on it if it were me.Just wondering how hot your sf2000 gets or any mean well 240w driver.
The board it self doesn't get too hot but the drivers are quite hot to hold an on the warmer days I can only just hold onto the drivers, is this normal? How hot is too hot for them to get?
