I wish my Lenovo laptop was quiet as my wife's MacBook Air....

1. small and light (as it should be)
2. with a noisy and constantly humming fan
3. while running RHEL of all possible Linux distros.
I surely appreciate his message about noisy computers.

That said: yes, it's just great without noise.

My config is at http://wingolog.org/pub/thinkpad-x220-thinkfan.conf. Copy to /etc/thinkfan.conf and then run "thinkfan" as root. Soooooooooooooo much better. (No warrantee of course.)
I have no idea why the kernel doesn't handle this already.

I did remove the supermicro 5 bay sata hotswap hardware when I switched cases. I am sure it was responsible for some, but not all of the noise.
The p182 has 3 layer doors and side panels, and silicone washers for the hard drives. Also the power supply mounts are silicone.
Switching cases takes a few hours, but can be a pretty cheap way to help quiet a computer.
iMacs and loud fans
Posted Apr 20, 2012 19:04 UTC (Fri) by gwolf (subscriber, #14632)
Apple hardware is good when running Apple software. I don't like Apple software. So, I prefer the quiet humming of my regular PC.

I figure a fanless, or nearly fanless, i7 system should be able to be built with just spending a couple hundred more dollars then a normal desktop.
example of what you can get...

I am not sure that a completely fanless computer with an i7 is possible at this moment, no matter how many heatpipes you use: in fact anything with a TDP bigger than 35W is going to be hard to cool without fans. Update: I found this monster which apparently can do the feat, but it is going to add a bit more than $200 to your computer (hint: the iMac will appear to be cheap in comparison).
Posted Apr 20, 2012 23:57 UTC (Fri) by drag (subscriber, #31333)
Yes, yes it was.
PSU is generally the noisiest and crapiest part on a modern PC when it comes to keeping it quiet. With those fanless ones then it makes making a quiet PC massively easier.
> In my recent research I have not found a single fanless computer with anything fancier than an i3 2120T or i5 2390T, and those cost about $200 more than a normal desktop; the Aleutia Relia I mentioned above is an example. It features a CPU cooler made exclusively with 6 heatpipes connected to the case, which acts as a huge heatsink.

That is why you have to build it yourself.
Notice how they call them 'industrial'. You can go to logicsupply.com and see a whole mess of different fanless models. I would never think of purchasing one of those things for a home system.
They have to meet specific requirements about being able to operate in certain temperature ranges, survive vibrations of certain levels, exist in dusty environments, deal with humidity, and other things that don't matter for home systems. This is why they are expensive. Compared to traditional 'rugged' systems they are dirt cheap and much faster, but I still wouldn't care to buy one for personal system.
Seeing how you will likely just run a computer in a air conditioned living room there is no good reason why you want to spend money on a system like that. Especially if you don't care about it being small and pretty. Just get a nice case and buy the biggest ugliest heatsink you can. Worst case if convection isn't good enough you can slap a 120 mm fan on it and put a resister inline on it and run it at a very low speed. You won't be able to hear it above the central air conditioning in your house.
I've built a number of 'quiet' PCs in the past. My last one only used one fan beside the power supply.
The last one was on a Pentium-D. It was dead quiet with a single undervolted 120mm fan for the entire system. I even bothered to build ducts for it out of cardstock and tape. The heatsink was one of those 'tower' heatsinks and the cpu ran barely above room temperature, literally. Total overkill. That was with what amounted to 2 3Ghz Pentium 4 cores with a TDP of 95 watts. It probably was about 200 mm tall and featured 6 heatpipes in a 'U' shape so that you effectively had 12 heatpipes. I still use it as a server system in my basement.
The CPU barely matters nowadays because big aftermarket heatsinks are good and cheap. The biggest problems are the video cards, hard drives, and power supply. With a fanless power supply, SSD drive, and a integrated GPU then it's relatively simple.
Nowadays I just use a laptop, though. If you want something smaller or pre-built then just buy a laptop and place it behind your desk or something. That is essentially what a iMac is anyways.

Have a look of the following site for the case manufacturer ;)

Even without water cooling it's relatively easy to get a noise less system. You just have to remember computer noise comes in two varieties, vibration and air movement. By isolating vibration sources and slowing down air movement you can bring decibels way down below the human threshold.
Realistically though the easiest way to get a quiet system is to find an under-clocked laptop with an SSD. Not only does the under-clocking reduce noise it reduces heat output significantly.

I know that mini-ITX motherboards and cases are available but why not have a smaller case for an ATX motherboard?

The hard disk will be an SSD (unless you are really strapped for cash - in which case why are you building a system from scratch instead of buying secondhand?).
What makes you think there's going to be just one hard disk? The largest available SSDs are still under 1TB, and that's just plain not enough space for a lot of users. You can fill 1TB with digital photographs and video very quickly. Not to mention that people who are keeping things that are precious to them are likely to want some kind of redundancy in the event of a drive failure, which means having multiple drives. That may not call for a full tower case, but it certainly justifies something with some expansion room.

Tower cases for quiet PCs
Posted Apr 22, 2012 7:43 UTC (Sun) by Cato (subscriber, #7643)
I have a Core 2 Duo E8200 with NVidia GTX260 in an Antec P180 case, with a good (large) CPU cooler and a good quality quiet PSU - all this would not fit in a minitower case while still retaining good airflow for quiet cooling. I can only just hear a soft fan sound while gaming, and the setup could be upgraded in various ways and still stay quiet.
The problem is that quiet PCs are treated as a black art, with magazine/web reviews barely mentioning noise levels (and never quantifying them), consumers not knowing what to look for, and PC makers generally not building quiet PCs. Once you know the sort of parts to use, it's not hard, but quiet PCs will cost more than a typical one.

Never say never. For example: cooler review and diagram from it, videocard review and diagram from it, here is review of PSUs without fans and when regular PSUs are reviewed there are diagrams too.
It depends on who does the review, really.

A tower case doesn't guarantee that the card will fit - my HP x8400 'workstation' at work doesn't physically fit a Nvidia 4500 x2 double-width card, which is a bit shocking really.

A big 120 mm fan spinning slowly will move as much air as a small fan spinning fast, except the first one will be nearly noiseless and the second one — not at all. The only part that can be difficult to silence is the gpu as there is no room for a big fan on a PCI card, so either you go totally fanless for the GPU or it will drown the other parts in noise.

Of course, maybe the quality of the thing is worth it; I would certainly consider it if I was Linus and made $200k/year and had a huge house. As it is I prefer a slicker and cheaper machine, preferably custom built.

I expect that when ARM processors with multiple cores enter the market in full force, we will get much smaller and quieter computers by default. I share epa's comment above about the dislike for towers.
Posted Apr 20, 2012 22:01 UTC (Fri) by man_ls (guest, #15091)
On the logistic side my operation has been a triumph: all bits from five different providers (one international) in less than a week. But the assembled result did not work and I am still trying to figure out why, now with the (paid) help of a local shop. Probably a faulty motherboard, the thin wisps of smoke I have seen twice are not a good sign they tell me.
As to pre-built options, there are some almost fanless and a few truly fanless like the Aleutia Relia, but the options are quite limited. For instance I wanted an SLC SSD disk and I have not found any preassembled machines. I would have considered a Mac mini if I could be sure its Debian support was good enough.

And you thought computers run on electricity?
Wrong, they run on smoke, and if you ever let it out they don't do so well!
Posted Apr 21, 2012 20:21 UTC (Sat) by man_ls (guest, #15091)
I promise I did not overclock it, if anything I underspecced the PSU (and other components) to make it run cooler.

That fan is actually a good thing if you are generating a lot of heat. It means you aren't destroying your machine.

I can see for home-theater purposes why this might be a good idea, but it's not too hard to keep the computer away from the viewer and run longer cables.
