Hi Steamx,

Yep, I have noticed that usually when there is a heat problems people tend to fix it by transferring heat away. Usually by fans etc.

It all comes to power supply efficiency. Lets say that HDD takes 10W and when using PS with efficiency ~70% PS generates 4.3W heat.

My approach would be to understand the power supply requirements and either find best available power supply or to design one by myself.

To be able to do it I need some schematics to be able to measure the maximum current taken from each power supply branch (for example 3A from +12V, 2A from +5V and so on....)

So anyone who has some info about power management and maybe schematics/block diagrams of power supply in DM7025 please let me know.

question
As the power supply dominates the heat generation on DM7025 then the power supply's efficiency is of course low. Do you know if there are projects which have tried to replace the "in box" DM 7025 power supply with something better? Have you heard if anybody have tried to design such a power supply?

best regards,
