anybody heard of a fanless cooling system

[boyz]

The thing that bug me is the buildup of dust in your cpu case, every body design faster and better pc part but the cooling system remains 19 th century.......if you heard of a fanless cooling system let me know plse. Thank you

Water cooling can use a minimal amount of fans, but not totally eliminate them. I don't really have any problems w/ dust, maybe you have an airflow problem.

Are there more fans blowing out then in? That could be the problem. For intakes, if you use filters (and clean them regularly) you can have pretty much a dustless system, but even without intake filters, at least the dust will stay in one area (where the fans) if you have more air going in then out, otherwise, dust is sucked in every peep hole you can imagine.

this article goes more in dept on proper air flow.

I don't think so, i have a 120 mm fan for the intake with/out filter dust still get in through the cdrom cracks and other holes in the tower, the pc runs with 5 fans, one 120 mm for intake, cpu, one over the cpu for exhaust and power supply 2

Do intake filters really help a lot? I also want to keep my computer as dust-less as possible, but I'm sort of afraid that introducing filters will limit the airflow. Am I wrong? I have two front intake fans, a side intake fan, and two back outtake fans. I was thinking of getting filters for just the two front fans (dont want it for the side because its on an acrylic window. Is this recommended?

Filters do work well, as I've seen a lot which get clogged after a while if you don't let dust build up too much on it then I don't think it'll reduce air flow much.

if your not going to filter all fans, its kinda pointless to do it at all you know. yes it cuts airflow, but thats the price you pay. since your exhausts don't have filters they have better airflow, negative pressure is bad and sucks in dust you need more intakes then outakes with filtered system.


i remember reading a review of a water cooling system where the guy took the fan off the radiator thing for kicks to see how hot it would get. it was within operating spec, so you could run without fan with some or very very low rpm fan. i'd just suggest getting a rheobus/fanbus and slow down every fan in your system. thats what i do. you gotta do that to your psu unless its really good at lowering its fan speeds by itself.

I don't have the link anymore, but I read about a guy who built a fanless water-cooled system by burying a fiberglass tank in his back yard. He uses that as his 'radiator' and eliminated all fans.

It is really hard to build a positive pressure (air vol. in > air vol. out) cooling system in most of the cases that are available because they have so many leaks.
But if you can, you can have a dustless system - just filter the fan(s) on the air-in side (have to make sure air can't reach intake fans by going around the filter - For as they say, "Air, water, electricity and students all take the path of least resistance.") and keep the filter(s) clean.

Hoping for some :sun:!

Here's one

As "sexy" as that water cool system look i rather stick with my fan, i don't want my pc to look like a fish tank.

Here's a fanless system that I've been wanting to put together to use as a development server. You won't get the greatest pc from this but it is fanless and silent. It uses the EPIA M10000 platform from VIA.

My old 486 was fanless

Seriously, try some quiet fans and get intake filters. They will lower your airflow a bit but I don't think it should be a problem. I have filters on my cases (cheap A/C filter foam from Home Depot. Like $3.00 for four feet). I vacuum the filter once every two weeks or just replace it every month. I have little to no dust in my system. Of course, there are always ways some dust can get in, unless you start sealing all the "extra" holes in the case.

For some serious $, there are real good 350W fanless PSU's here

That will only cut your PSU fans though

As for cutting dust, positive case pressure does work. Dust won't come in the crevices because there's air blowing out of them. That is the whole point of positive pressure - the effects of "leaks" are negated. You must, of course, filter all your intakes well. I just take out the filters when they clog up and wash them with soap and water, put them back when dry, about half an hour.

you'll probably have to mod your case to add intake fan(s) to get more air in than out. A rheobus is pretty crucial too. You don't want 90 psi out the cracks or anything, the positive pressure is very slight. I adjusted by holding a burning incense stick by a drive bay crevice and tweaking the fans with the rheobus until the smoke was barely blown away from the crack instead of being sucked in.

Yes, the filters cut down the flow versus not filtering. This in no way means you'll necessarily choke your case for air. You just have to plan things. There's different filters too - higher flow ones that don't filter as fine, and really fine ones that cut the flow more. Your typical case fan filters don't dramatically mess up your flow. Flow increases with noise and dust Everything is a tradeoff. HTH

Yeah, why waste a perfectly good blunt!

A little bumpage, since I made such a sincere effort in my obviously correct and awesome response

Seriously, boyz what you think? Inside my case is pretty clinically dustless

Yes, there is a fanless cooling system coming.

Directron has posted the following upcoming product to their web site. They claim the entire case is one giant heatsink; it uses copper heatpipes to transfer the heat from the cpu, graphics, hard drive to the case. It also has a fanless power supply. They claim it will cool a P4 3.06.

I doubt this case will be cheap...I'd guess around $300. Email Directron and tell them you want to see stock of this case asap.
