Welcome to the forum kees. I'm not sure if you're looking for a ready computer or are you going to build one. It's also difficult to help without knowing all kind of stuff, like: - what kind of connections you need to the back panel? - what programs are you using? - do you need video playback? How g...

How about investing 50$ more and get it soon back in electricity bills?
Your kids ears would probably appreciate this solution too:

I'm starting from point zero (meaning I have nothing yet) and I'm aiming for a tiny, energy efficient, passive cooled build just barely capable for the following: - tiny Linux MediaCenter OS - 7.1 audio via HDMI 1.3 - HD 1080p video - WiFi (Wlan N) - remote control Parts I would like to have recomme...

Very nice thread for comparison, this could be moved to Green Computing ? System: E8400 @0,8V 1,8GHz Nvidia G210 4*1Gb DDR2 800MHz 2*HDD (Seagate, WD green) Seasonic 380W no fans (except one Scythe inside PSU) Watt-meter readings from 240V plug* Shutdown: 4,5W Idle (HDD's on): 77W HD-playback: 89-91...

It should be easy if you have a change to setup water hoses high above your system. Even better if you have a cool place up there which water must pass during it's journey. I'm using same idea with air cooling and I have been able to remove all fans from main chamber of P182. http://www.silentpcrevi...

I was also thinking about water cooling couple of years ago. Back then there were not quiet enough pumps, and what i've heard later is that some of them are getting noisier in time (maybe because of moving parts loosing their best performance?). Well, i didn't enter the water world at all but i buil...

How about adding a slow fan to the chimney? :) (top or middle) Wider chimney perhaps? If you can find another spare tube. Could make for an interesting comparison. Thanks for ideas, but... - If a fan would move the air, chimney would have no use. It's either chimney or fan, and in my case I wanted ...

That's the TDP and surely never reached in normal use, I think that normal use add only 1-3W to idle consumption. Maybe you can reach the TDP with 100% burning thou? After undervolting I'm getting that 17W with 100% burning, but I have not used the meter with normal voltage so I couldn't tell at the...

Hi all, I just found a wattage meter in our library! They seem to borrow a lot of things among books nowadays... I borrowed it and got some true watt readings for my chimney-PC PC at idle (windows+startup programs only): 73W PC at normal use (browsing, office work etc): 78W PC at 100% burn of CPU+ME...

Let's have this thread up again and let's have other systems included, we didn't get so many results here when this thread was for passive systems only. I'm trying to help us all to find out best combinations of MB/CPU and reasonable cooling for any required performance. "Speed against temperature" ...

Now, I know the plug-and-play WC systems (like that little Corsair thing) don't really cut it, but I've always heard that a good water cooler - particularly with a passive rad - is about as quiet as you can get. No? No. Never has been -- I'd say SPCR enthusiasts' top air-cooled systems have been ch...

Great numbers for power consuption! How's the performance, could you run some tests?

Nice to read a well written project article with lot's of good photos

lower air pressure in top of the room Wrong again (although it is a little lower, like it is just 1/3 on the top of Everest) Please explain how you see the situation and where you think the NPP is? In my opinion: When the computer is off, I suppose it's exactly 75cm down in the tube. When there's 4...

the pressure is (and must be) the same inside the case and in the room.. Wrong. If it was, there would be no reason for the air to enter the case. You're right - but when the replacement air enters the case from big intake vents the pressure is soon balanced. Then the chimney causes negative pressu...

Inside view

Chimney is painted to same color as one other wall,
image of the ready theatre setup in this thread

Where on earth did you get such a massive cardboard tube though? I asked for tube in a local hardware stores selling floor carpet. The tube inside the carpet roll was rubbish for them, so I just got one for free and cut the lenght (1,2m) with a saw. technically I think your setup would be considere...

One thing more: Make sure you don't have any other things reducing the voltage at the same time. (resistance wires/BIOS settings/software)

Is it possible that the FanMate reduces the voltage under the lowest voltage that keeps the fan rolling? There are two important voltages for each fan model: one that starts them up and the minimum that keeps them rolling. Most fans need at least 8-9V to start and 5-7V to keep rolling. Horizontally ...

In a long run: updating hardware to a laptop is difficult compared to case build. Hardware updates are a necessity expecially in gaming and you'll propably need to change something inside there (GPU?) within couple of years. In a short run: Yet, laptops are still more expensive when comparing the pr...

Final looks http://maalitehdas.wippiespace.com//images/everest/26052010010_519x800.jpg P182 is located behind the TV, you can see the chimney painted to same color with the wall. The system has been running almost 4 months now so now I can really say it's working - and the TV is the noisiest part i...

I have a totally passive build. HFX mini case, heatpipes from cpu and gpu to the case. It was the most horrible thing in my life to put these parts together. Anyway, here's some results. Load tested with Everest. (e5300 @ 2,6GHz & 1.05V, GT240, 4GB RAM, SSD) Ambient temp: 21C GPU idle: 36C SSD temp...

I would say one of the biggest changes in 5 years besides OEM's acknowledging that customers do care about noise, is the increased power efficiency while still increasing speed. I am still a bit leery of SSD... ...probably because of getting burned so bad with the CD manufactures claims that my mus...

I don't know if my calculations are including enough information, but this result will get me to test it in practice. I'm going to fill my case (P182) with some material to reduce the airspace and check this in practice. That would *really* be great! One thing I would recommend is to try to *not* i...

physics: (1 cubic foot = 0,0283168466 cubic meters) P (power turning to heat inside case) = 200W C (air warming capasity or something...) = 1006 J / kg C o (air mass) = 1,293 kg / m3 V1 (case1 interior 20cmx50cmx60cm) = 0,06000 m3 V2 (case2 interior 17cmx45cmx50cm) = 0,03825 m3 t (time) = 60 s T0 (a...

I agree with danimal here

when idling, all that can be heard is the spinning of the hard disks. With an ambient temp of 20c, idle temp is 26-27c and load temp is 51c I don't see much benefit from WC, reading the above (It will not reduce your HDD noise and you don't need any more cooling power). Actually I would see that yo...

G210 can be compared to old GF8000 series in performance (GF8600 is closest to it I suppose) and compared to HD4000 series it's performance is somewhere between 4350 and 4550. 40nm technology gives that performance level with very low wattage and low heat levels. GF250 is an upgrade based on GF9000 ...

You're component list is looking good in general, I think you're able to build it nice and silent enough. If you're not gaming, please consider a lower wattage graphic card. Pick one with HDMI out and all those fancy sound formats you might need. All HDMI-cabable video cards, starting from GF210, ar...

Video cards themselves can handle quite a lot of heat, some I've heard have run nicely even at 145C. I suppose it's pretty rare to overheat a GPU if there's any fan spinning at any speed towards it. What should be considered, however, is that the GPU heat get's out of the case as directly as possibl...
