AudioLinux and NUC Troubleshooting and Tuning

[sig8]

Is there any other  fanless case for NUC7i7DNHE, than Akasa Plato X7D? I just got one but don't like the idea of connecting cables inside for power, USB, etc. That sort of defeats the whole idea of small footprint (that includes cables, extension wires, etc. in my mind).

I don't think there is anything yet. I sent mine back, thought it was too big.

I took the fan out of the original case, replaced the heatsink compound with arctic silver and left it at that, temps are 44 degrees.

 

Are you using it as a server or an endpoint? I don't think this case is necessary for an endpoint, even in extreme mode. Correct me if I am wrong. Thanks.

I just opened the NUC and Akasa case. NUC has a very good copper heat sink with fins, I don't think you will do any better with any heat sink in the available space. What they have is very good in the available space.

 

Akasa case is another story, it is a big hunk of aluminum, but they have black anodized aluminum contact surface, ..... really? I have to do some research, but that black anodizing will work as an insulator between CPU and the heat sink, meaning it would prevent heat to transfer to the heat sink. They should have left that part bare IMO. It will transfer heat to ambient due to large surface area, but if heat from CPU to contact area cannot transfer easily, what good is the larger surface area. I don't think  I am going to deploy it. 

 

But for those who are or would use it in original case, just disconnect the fan connector from board and leave that fan and the copper heat sink in place, best is to remove fan and leave heat sink in place to allow free air movement in and around the copper heat sink.

Why heat cannot transfer easily?  One should apply the thermal paste and the thermal pad.  They should be effective.

Leo: The anodizing on the heat transfer block on the case would act as an insulating layer. Copper has better thermal conductivity than aluminum, and bare aluminum has better conductivity than anodized aluminum. As Dev has pointed out, they did not anodized that surface in another case.

This is talking about heat transfer by radiation, we have conduction here. Two very different things.

 

It is about good, better, best. If every degree temperature difference matters in SQ, then it matters. I just pointed out something I saw and did not think was the best thing to do. We fuss about everything, don't we.

It’s a SR7EHD MR4 and the 8A high power ouput regulator module is malfunctioning and needs replacement. I don’t know the cause or what’s wrong with it exactly. All I know is my i7  6700T music server connected to it started acting up end of last year and its output voltage had dropped to around 10.5V. Couldn’t get it back up to 12V using the potmeter (got to about 11.6) but it became more and more unstable. Today I got my old HDplex 12/19v (v1) PSU back into the system as the server either didn’t boot completely or rebooted after minutes. I’m now waiting for Hynes to send me a replacement module.

Which DC-DC ATX you are using. Does SR7 gets hot when you use it with 6700T with 90W TDP?
