I only would like to know if they is some really dangerous thing happening turning out the fan like explosions or fires
If finally will buy one I will buy one of those that connect to a power adapter, like a laptop because I do not need so much energy and they are 93% power efficient and much more cheap.
However, efficiency is over-stated.
Yes 96% DC to DC. But the power brick is the one converting from AC to DC. Hence your total efficiency is really much less. However, for a very low watt system, it is silent and the way to go.
87% efficiency stated...don't have any independent verification...but assuming it is accurate.
100 watt needed DC/.97= 103 watt at brick./.87=118 at wall = about 85% efficiency....not bad for low wattage applications.

So, find out what fan it uses and the RPM, and get a lower RPM fan of the same size to replace it. You will want to try to find the startup voltage required for the new fan, the lower the better.
Does the PSU vary fan speed based on load already?
HI, do not understand this. This mean that a normal PSU could have similar power efficiency than one of those external adapters? I always have suppose that they put the power efficiency of the whole pack, not only the connector.

Hi, thank you for your advice. I had read about this problem when dismount a PSU so my idea was simply to cut the fan cable from the outside.
