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...

I swapped the CPUs but nothing happened (as expected, more or less). It was wishful thinking on my part as I wanted to replace my V-locked Venice with that undervoltable Winchester. :cry: I swapped the PSU too but no changes. A weird thing happened though. One time the pc turned on and I got to see ...

No worries. I've always found your posts to be very useful and informative. I do hope you're still doing the occasional power consumption test. Thanks, Kriz. I haven't been doing any power consumption tests lately, but I can't say things are improving as radically as they did two-three years ago. T...

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-...

PC crashed: what could be the cause?
It had to happen sooner or later, my first hardware crash. When I tried to turn on my PC two days ago, fans started to spin, lights turned on, but no booting, no BIOS even.

Benvenuto, Bembotto! The Asrock boards I have tested so far (NF6G and NF7G-HDready) were very efficient, which has been affirmed by various people in different places. I have tested the 4450e on a nVidia 7025-board by Abit, which was also very efficient. Under 100% load and without any undervolting ...

I didn't have time to fiddle around with CrystalCPUID but I definitely will with the next Brisbane I get my hands on. I'll go to the Rightmark forums and ask again, because it really is a shame the undervolting with RMClock doesn't work as well as it used to with previous Brisbanes and still does wi...

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...

From what I read on here the 7050 wasn't as good a the 690/780 but I maybe wrong. Have you got some figures for it ? 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...

Merci for posting this, guerby. These are very interesting figures. Unfortunately I haven't tested any quad core configurations. I calculated some time ago that a setup similar to yours with a Q6600 (G0 stepping) and a GA-EP35-DS3P would consume around 80W at idle. But I can't remember how I got to ...

Palindroman, swapping the 690v to the 780g everything else the same I'm using about 38-40 watts as I was before when idle. So it compares well imo. Xen, the 690v used a 3-4 watts less than the 690g according to wikipedia. thejamppa, 690v does not have the digital interface "lacks support for TMDS o...
