View Full Version : COMPLETELY silent PC
I'm looking into building a totally silent PC sometime in the future. It will serve as a frontend (one of eventually many) for my mythtv setup. I'm looking to cram it into a 1U rack enclosure or similar. What I'm thinking about is a Pentium M processor, passive heatsink, Use Gigabyte's Ramdisk as a HDD, If any optical drive a slimline DVD drive (possibly burner) that wouldn't be powered all the time. Graphics would have to be onboard, hopefully giving good enough quality, either through an s-video out or an external scan converter, to work well with my TV. Hopefully this will be replaced with DVI and a HDTV in the future, so an onboard DVI connector would be nice, but not required. Also, onboard sound would have to have toslink or SPDIF out on it, since I wouldn't trust an onboard DAC, and even a good one would pick up tons of interference with all the components in the case. The only avalible expansion slot would be used by the ramdrive.
My big thing right now is power supply. I'm currently thinking about getting a 1U 12 or 24 VDC power supply and have the AC/DC converter external. If I was using a bigger case, I'd use the antec phantom, but that won't fit into a 1U case.
So, any suggestions for this project?? If it goes the way I want it, it will be dead silent all the time except when the DVD drive is in use, which would usually mean music or a movie was playing to cover up that sound. The only thing is that ramdrive can only support up to 4 gigs of ram in it. Mabey i'll upgrade a a 2U slot so I can fit 2 ramdrives in it and a good video card. Could you imagine 2 SATA ram drives in a RAID 0 array?? Wow.

Yeah, I saw that, posted in it even. What I'm trying to do is a totally silent PC, most others are just quiet PC's.
I was going to say waterbox but you want small..... so I dont know :D
I've thought about doing a central water cooling setup with the resivor/pump in the attic or basement, then just running tubes thru the house. With that I could even have a radiator that would cool w/ air from outside in the winter and cool w/ air from the AC during the summer. That wouldn't work too well for a rack case though. That was mainly gonna be for the servers, and I'd put the desktops and any other computers that were big enough into it. That's gonna be a LONG time before I put that in, if I ever do. It'd be a sweet project if I did thou.
(And noise isn't an issue for the severs, 3 computers with 8-10 10,000 RPM drives each. You can't hear the fan noise over the hard drives spinning. If I pull the RAID drives in the front, it's like when a plane lands and the jet engines are spinning down. After a reboot, once the drives all spin up (they don't spin up at the same time), it sounds like takeoff. Pretty sweet!)
Thanks for your help
If you think it can be done, it in fact can be done. Now gitting it to work is another story all together. :D
Good luck to you sir.
Right.. it can be done. Easy enough. Why the 1u enclosure though. Leaves you pretty tight on heat sinks! Do you not have room for anything more?
I use a commell itx board.. and should think there p-m boards are as good as there 478 boards. However I wasn't about to get a great pic on the onboard gfx dunno why.. probably everything being a bit close together was giving some interferance somewhere. I use a low profile fx5200 though anyway so doesn't bother me. Only noise I really have is the heat sink fan cuz my CPU needs cooling :(
Seeing as this is just a front end RAM disk should be fine though never used one myself. However laptop HD's are pretty quiet (and cool). Especially when soundproofed up.
Yeah, I'm leaning more and more towards the 2U enclosure, thatway I can have good graphics card and free up another PCI slot for something (mabey ramdisk, mabey soundcard).
I've seen the passive heat sinks for pentium M's, anyone know exactly how big they are??
how about a Zalman TNN case? no fans at all, even for the PSU but they recomend a quiet 120mm fan running at 1000rpm.
I like the look of the Zalman case, but it seems way to large for what I'm gonna be using it for.
Look at your hard drive. There should be either an IDE or SATA cable. Next to that, there should be a molex or SATA power connector. Unplug that. 100% silent hard drive :)
Seriously, you could try a Zalman TNN case
yeah, these days the hard drive is normal the loudest part (epecialy went its dying, but hey, who wants to go out in silence.). When my laptop hard drive goes to sleep its 100% silent because nothing is moving.\
You could try a seagate or samsung spinpoint, i've heard good things about them.
