Title says it all - got this unit from roc-noc 2 months ago: http://www.roc-noc.com/product.php?productid=177
I just started paying attention at all the bells and whistles on this one and found out about the high temp.
FWIW We began shipping our assembled RB450 and RB450G products with 12vdc power supplies on June 1st. We found that they run pretty warm with a 24vdc supply and much cooler with 12vdc. My belief is that cooler boards should last longer.
Contact me offline if you want to trade out the supply.
Many thanks,
Tom
PS We still ship 24vdc supplies with most other models as they seem to run cooler.
