Greetings all, I'm watching a thermometer sitting atop the air vents over the DAC chip of a BII/Legato. [The power & I/V resistors are mounted with air space underneath the Legato board.] Steady state is around 115-117F, or ambient plus 47F. In your opinion, what air temp around the DAC would cause concern? Edited by user Thursday, February 17, 2011 7:37:57 AM(UTC)

That's difficult to answer, but I would say you are perfectly fine as you are. As long as you are staying within the specified voltage ranges.

Thanks Russ, Yes, the Legato supplies are 15.0v and lower. I think the 5.5v Placid is the largest heat producer. I had originally installed nice-looking mesh ventilation screens in the case but they blocked too much convection and everything got pretty hot. Current case ventilation (shown in link) seems to level out at 'warm'... http://files.me.com/francolargo/pfr8uu Edited by user Friday, February 18, 2011 8:56:15 AM(UTC)
