Re: Passive house ventilation with computer fans

Hi Ian, My first thought is what lengths are the ducts going to be? The first duct about 1.8 metres, the second 1.3 metres, the third, 3 metres, depending on the size of the bathroom. Would something like this trickle extract fan be more suitable? I looked at fans like these for a while, but usually...

Re: Passive house ventilation with computer fans

Interesting project, and outlining all the details makes it easy to understand! More later, after I've re-read and thought more about your project. Thanks for the feedback, Mike. We had some contact years ago concerning the low-power computers I built. I had to give that up because it took up too m...

Re: Passive house ventilation with computer fans

Thanks a lot for your reply, mercyfull_fate. In the past two years I've given a lot of thought to the central vs decentral issue. In fact, for a long time, I thought we would use the Hoval HomeVent RS-180 because it's very well-rated and it also recovers moisture (which is very important in a passiv...

Passive house ventilation with computer fans

It's been a while since I last asked a question on the SPCR forums, but I'm pretty sure this is the right place to ask for feedback and advice on a project I'm working on. Many thanks in advance for your comments. Next summer we're planning to build a 85-90 square metre (900-950 square feet) passive...

Re: Kaze server fan controller

Coincidentally I'm planning on doing the same thing in the future. I want to use the fan controller to get airflow going through my home, because it would allow me to buy a decentralized ventilation system, which is much cheaper than a centralized one, much more energy efficient, much quieter, and n...

Thanks for all the answers! Well, the only way to tell what part exactly is bugged, you have to replace/test each part individually. Sounds like motherboard to me, although it's not more than just a hunch. Instead of buying a "new" 939 processor, why don't just take it as an "it's-time-to-upgrade-a-...

X2 4450e tested on Abit AN-M2: very low power

I've had my eye on the Abit AN-M2 (nVidia 7025/630) for quite a while. I knew that it was one of the most efficient boards around, right behind the Asrock Alive NF7G-HDready. Unfortunately I don't have the money or the time to test every board around. Besides, I was very happy with the Gigabyte boar...

Go with the Seasonic as it'll consume (a lot) less power for sure. You'll have that 20 bucks back in no time.

250W is plenty power for your config. I tested a similar setup last week and it consumed max 175W.

After testing the 690V (which was a disappointment) I haven't tested any 690G boards. I now see that the higher power consumption was mainly due to Gigabyte, but I still think nVidia...
