Greetings all!

Any opinions why I should or should not have LOR DC card and power supply in same box?

Thanks in advance!

Only reason not to put them both in the same box is cause it would not fit. Have had this situation for the past 2 yrs and not problems. Going to have another one this year. Just be careful that there is no chance that the A.C. current shorts to a D.C. path.

Do you have any vent holes or a sealed box?

Thanks!

Ok, first I need to say I live in mid Missouri. So the evening temperatures are about 45 and day might get up to about 65. I just use the good old stand by CG-1500 box. These are not air tight so some air exchange is going to happen. But I have not added any extra vent holes and doubt that anyone else has.

I see.

I plan on using this for shows year- round. The temp was in the hundreds for my july 4 show.

I'm really leaning toward separate boxes. I was hoping I would not have to use fans as well.

Maybe both in 1 box with a fan?

Thanks!

Is it a PC power supply or one of the smaller low-profile supplys? Does it already have a fan? You can install a small 2"-3" muffin fan if you desire, exhausting outward to vent the heat.. the board itself shouldnt get that warm.
