Ask Slashdot: Passively Cooled Hardware For Game Emulation?
akutz writes "I recently sold a 2011 Mac mini on Craigslist because after using it to rip my Blu-ray collection, I tried to use it as an emulation station connected to my TV. However, emulators like Dolphin, BSNES, etc. would cause the Mac mini's fans to spin up like turbine engines — much too loud for my liking. I ask, therefore: What hardware would you recommend for building a passively cooled mini-system that will serve as a media center's emulation station?"
i've ried to go fully fanless, with very low-power CPUs (atom, E-350) and no graphics card. The T climbs quickly. OTOH, a low-power CPU (i3 2100T with the included 600 RPM fan, a PSU with a quiet FAN and an 80+ gold rating, and probably no graphics card, will make no audible noise, less than the hard disk. silentpcreview.com has lists and reviews of components.

Right; the next jump from "the Mac Mini fans are too loud" doesn't have to be fanless, which is particularly troublesome in an emulator situation where the CPU will always be running. The key to low noise fans is to get big ones that move air even at lower speeds, which right now means 120mm. Using fans that are too small, in order to make the case really tiny, is what the Mac Mini does wrong for this application. A case like the Sugo SG05-B will give you those in a reasonable form factor. It won't be tiny, but there's a fundamental trade-off here: you can either make your fans cool well, be small, or be quiet--never all three at once. I have done here on past emulator boxes is to use a case with a larger fan like that, combined with one of the Zotac Mini ITX boards using an Intel Atom processor.
