What percent and mother to take for a server with passive cooling?

Question

Iron

Tell me, what percentage and mother to take for a server with passive cooling?
Tasks: Spin web services, blog and file cleaning with a torrent client on a bubuntu server.
As an option, you can offer a mini-pc a la raspberry / orange, but with the ability to connect via sata drives.

Answer 1

Set counters, count the load in the period. By load, look for a percentage with the lowest possible TDP, look for a board for it. Do not forget about the reserve of % 20. The rest is either from a cannon on sparrows or you will soon hit the ceiling.

Answer 2

Prots - look at heat dissipation, it is desirable that it be below 50W
From examples: i5-4570T, i5 3470T and so on.
Mother - look towards full-size atx with good cooling on bridges. It already depends on the socket.
Collecting a mini PC is either sacrificing power or noise.

Answer 3

Artem has already recommended them to you :) They are a whole family from 18-watt j1800 with a beautiful heatsink (but I put a fan there anyway), to 4-core 5-watt ones (but they have ugly heatsinks, they had to be changed to sprawling ones for > 65W). Minus - only 2 sata and only 8Gb RAM.
1. If you want from the usual (up to 128Gb RAM, 8 cores, a raid of 4 disks,...) - you can simply make a big heatsink. Buy a profile and put on it. CPU 65-200W So choose (at least in a chippedip) a piece that is suitable in shape and size. You can still add a large (120..150..200) fan but slow it down with a shim. It can be made in the shape of a mushroom - a copper leg and then a cover with ribs above the board. Or slots for memory and connectors or a high leg (and you can go there peltier).
If you want to open it sometimes - you can add tubes for cooling in case of overheating. The conda cover is screwed on, they are not needed (sewn from the blanket on top).
2. Buy copper, solder it into a vessel and put transformer oil into it through an external heat exchanger from something small (300 watts) refrigerated. Add a receiver and a pressure sensor, a pump, an LCD with flow parameters, display it on one of the sites disguised as a scientific reactor chiller, giving access via vnc (just look).
3. Attach an aluminum container with water to it - the bottom is like the bottom of a radiator, warm water goes up. Above is an aquarium with fish. Or a canister of mash. And lanka is a pseudo thermostat ... And display the parameters of the mash on VGA. For search :)
4. In the cave of forty robbers there are boards on the processors mentioned by Artem, but soldered on the other side, so that they are cooled by the body of the device. There you can attach a massive heat exchanger. Amphibian twisted me, did not buy.
For example STX-N39.
