I want a passively cooled desktop/cpu/gpu by 2016, power supply mayhave fan.

So far intel and/or amd is not selling passively cooleable CPUs for desktops ?! Could this explain the decrease in PC sales ? People diverting to noiseless tablets ? Amazing that no passively cooleable cpus seem to be for sale ? You could do this if you clocked them slow enough. Not many people are interested in doing that on the desktop platform. If you want something not many other people want, it will be either unavailable or very expensive. |

I want a passively cooled desktop/cpu/gpu by 2016, power supply may have fan.
I play to buy a new computer by 2016, currently I am concerned that the
computer I want is not for sale/possible. These things exist. They're just less powerful and/or more expensive. My "home office" is in the living room, so my home desktop needs to be very quiet. For about 5 years, I've had an AMD Athlon X2 4800+ passively cooled (with a monster heatsink), tho the whole machine still had 2 fans: one for the power supply about which I don't know much, except that when it got noisy I bought a new power supply; and another fan for the system, the typical 120mm fan running at the lowest possible speed. I retired this machine and replaced it with a mini-itx system hosting an AMD E-350, again passively cooled. This one doesn't have a system fan, tho I haven't bought a pico-PSU yet, so it still has a fan within the power supply. In the real office, I use a fit-pc2 which is fully fanless, and if you're interested in fanless PC, I recommend you take a look at www.fit-pc.com. Stefan |

It's slower at recompiling Emacs, yes. But tasks that were instantaneous still are and those that weren't instantaneous don't take that much more time that I end up having to drink 5 coffees instead of one. The only real noticeable slow-down is due to the insanely costly rendering on most web-pages nowadays. Back in the days one could just "disable loading of images" but nowadays even the "simplest" web-pages seem to want to open up 50 http connections to download umpteen javascripts and whatnot. So, for this reason alone, I'll be upgrading the E-350 as soon as a more powerful fanless mini-itx system comes along, indeed. Supposedly, "in the real office" your computer is just a little more than a terminal, right? No, it's my work machine. "Work" here means reading email, hacking Emacs, writing LaTeX papers, and working on other projects in OCaml. Stefan |

So far intel and/or amd is not selling passively cooleable CPUs for desktops ?! Could this explain the decrease in PC sales ? People diverting to noiseless tablets ? Amazing that no passively cooleable cpus seem to be for sale ? With passively cooleable cpu I consider: 1. CPU + heatsink with fins smallist, no fan, no other things, except maybe thermal paste interface material between cpu and heatsink. So two questions: 1. Which desktop cpu by 2016 will be passively cooleable ? 2. How many watts are passively cooleable with a small heatsink/fins, like gt 520 from asus is a good example. (Also the motherboard must be passively cooled as well as all other components except perhaps power supply, though if a modest power supply is needed might be passively cooled too, but a little bit of airflow seems wise... though would be cool if it wasnt needed at all, than no dust in pc which would be excellent.) Bye, * Skybuck. As a big proponent of silent computing, I've been slowly working towards a completely silent PC (which implies fanless). Here's a few of my notes. 1. Power supplies *can* be fanless; there are several on the market. But the one I ended up using was the SeaSonic X series, which only turns on its fan when necessary. Under normal situations (web browsing, email, MS Word, Excel, even youtube) the fan stays off. Only when I boot up games or photoshop does the fan turn on. 2. Heat management is key. You must have a case design meant to deal well with heat. For example, my PSU is mounted at the bottom of my case, so that the PSU stays as cool as possible, so that its fan runs less often (because no internal components heat up the PSU). 3. Completely fanless cases tend to have huge built in heat sink fins on the outside of the case, so that heat pipes from CPUs/GPUs can be connected directly to the case, to radiate heat. Due to attaching heat pipes to the case, it places some pretty hefty design constraints on your internal components, as they now have to be physical compatible with the case. 4. Hard drives make noise. In fact, in my current system, they make *more* noise than my fans. Aka, big fans moving slowly generate less noise than a hard drive. So if noise reduction if your objective, it is not necessary to be completely fanless, only to be quieter than your hard drives. 5. Water cooling can be very noisy, because water pumps are noisy (in fact, it's actually rare to find a quiet pump). Thus, a water cooled, fanless computer can still be noisier than a computer with fans. -- // T.Hsu |

Very nice, but for me unfortunately there is not enough "extremely rich IO", i.e. there are only 2 eSATA ports -- no way to connect my 4TiB RAID5 matrix composed of 3 disks. Best regards, Piotr |

So far intel and/or amd is not selling passively cooleable CPUs for desktops ?! Could this explain the decrease in PC sales ? People diverting to noiseless tablets ? Get an Intel D525MW, and pick the box/power supply to get a fanless one. Use a solid state drive. Very nice package, and insanely small. There are some units that can be as small as a paperback book. I have built a number of these systems for special applications, all totally fanless. The Atom CPUs run QUITE cool even with no fan-forced cooling. Jon The black box on the shelf is a Mini-ITX Atom pc, fanless, made by Logic Supply. They are good guys, very helpful. https://dl.dropbox.com/u/53724080/Tr...oot_Closet.jpg It snaps photos from an outside USB cam and posts them to a Dropbox folder, and it measures indoor/outdoor temperatures and does remote heater control. This averages a few per cent CPU load, so runs cold. Dropbox is very robust and is a great, easy way to do remote automation without the hassle of setting up a web site or server. -- John Larkin Highland Technology, Inc jlarkin at highlandtechnology dot com http://www.highlandtechnology.com Precision electronic instrumentation Picosecond-resolution Digital Delay and Pulse generators Custom laser drivers and controllers Photonics and fiberoptic TTL data links VME thermocouple, LVDT, synchro acquisition and simulation |
