Well I did mention it in my thread on the dual mono setup, but here it goes... It is a dual mono so two power supplies in the case and this of course can add substantially more heat with 2 power supplies with each other... You can get a nice burn from the top plates of those power supplies.
Actually the Ncore itself I have no worry about, the NC400 bolted is a heatsink right to the case. But the power supplies get pretty hot. And they do transfer a lot of heat back INTO the NC400 being bolted to the same metal.
My suggestion is use Vented tops at a minimum and they then stay totally cool. Just me but especially when spending this kind of money, and easily making it bulletproof as I had to build it myself anyway, why not?
By the way I used Arctic silver 5, really good pure silver thermal heatsink compound. Its sold right at radioshack too. Cheap to order online, but with shipping you can get it locally from Rat shack just the same. It drops the temp about another 10 degrees. The NC400 stays cold with no issue.
"Further on the power supply.
You can melt cheese directly on that top plate for sure.
I have seen some posters using a "Stacked" Chassis.
This is great accept it seems they put the power supply on the bottom under a plate then put the NC400 on the top.
It defeats the purpose in my mind, they are adding at least 100 degrees to that NC400 heat sink even if the NC400 is disconnected and the power supply is just on.
Reverse it and put the NC400 on the bottom and the Power supply on the top to let the heat rise out of the case is the way to go, and in my opinion I highly suggest VENTED top plates at a minimum for the power supply it really does stay dead cool without transferring all that heat back to the NC400's heatsink in the case with it which is kind of against the whole purpose.
Or I guess you could just go with power supplies in one chassis and the NC400 in the other, I doubt that is necessary just saying."
