Re: [vdr] Mid range CPU choice
I've been running a Shuttle SK43G with 2.2Ghz AMD, silentPC fan, silent 250W psu and replaced all the mobo fans with heatsinks for 3 years. time to replace. The fan is still quiet, but now the case vibrates a little, and the whole thing runs about 61 degrees - which isn't ideal. I'd like to go fanless and cool. What I like about the shuttle is it's size.

Re: [vdr] Mid range CPU choice
Thanks again. The Asus M2NPV-VM looks like a great choice for me since it is easy to get in Australia. I am looking at the AN-M2HD now and it also available in Australia. The Asus has Composite out and the Abit has HDMI. I have VGA, RGB, S-Vid, HDMI inputs on my TV. In order of best to worse for quality ? VGA HDMI RGB S-Video The Abit also has the newer 7050 vs the 6150 on the Asus. The Asus has the extra module for HDTV output while the Abit has HDMI attached to the board. The big question is does the 7050 chipset provide any extra acceleration in Mpeg2 encoding / decoding to the 6150 ? So many choices and so many factors.

I had such a solution with two DVB-C cards. But if you want crunch and muscle, VIA is definitely not the way to go. For Intel side I can share you the information that E4*-series is better in the way that they allow you to use multiplier 6, which results with standard fsb to 1200MHz when idling. For example E6300 will idle at 1600 MHz. But you should also take care when choosing the motherboard, because undervolting is the most efficient way to reduce heat and some mobos (namely all Asrocks) do not allow undervolting. -Petri ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

The most efficient CPU are still the VIA ones... Low power, very low heat, very low noise. There are lots of EPIA mobos (Mini-ITX for factor) with fanless CPUs around. With these, you get only one PCI slot, but everything is integrated on the motherboard. Using a good laptop-like power block (efficient and fanless), you can have a really silent setup (one slow fan for the whole system). VIAs are good, but if you need more processing power then you need to get Amd or Intel. I have following setup and it feels quiet enough, mostly thanks to the case design. Case is Antec's NSK-2400, cpu is AMD Athlon 64 X2 3800+ EE, cpu cooler is Thermalright SI-97A, motherboard is Asus M2NPV-VM and hard drive is WD caviar SE16. The case has two 12" fans on the side, just next to the heatpipe cpu cooler. So, no need for fan for the cpu cooler. Case fans are "tricools" and I run them in the lowest speed. I can't hear anything from the machine from one meter away. With Turion cpu you could drop one case fan out.. I haven't tested, maybe I could also. My cpu uses 65W of power and if I remember correctly turions use something like 25W. For processing power and cost I am looking at AMD AM2 4000 and Intel Duel Core E2140 and Intel core2 Duo E4400. I am open to other suggestions as long as they can currently be purchased in store. Since the system will be spending 95% of it's time idle I want a CPU that can drop down to the slowest possible clock speed with the least power consumption. I will also be using temperature controlled fans to keep it real quiet and any other ways I can find to drop down power and noise. Drop noise: * suspend the disk drive with rubber bands * carefully design the air path inside the case Look the design of Antec's NSK-2400 (or fusion). I think that's very good for air flow.

Low power, very low heat, very low noise. There are lots of EPIA mobos (Mini-ITX for factor) with fanless CPUs around. With these, you get only one PCI slot, but everything is integrated on the motherboard. Using a good laptop-like power block (efficient and fanless), you can have a really silent setup (one slow fan for the whole system). > For processing power and cost I am looking at AMD AM2 4000 and Intel > Duel Core E2140 and Intel core2 Duo E4400.

Drop noise: * suspend the disk drive with rubber bands * carefully design the air path inside the case -- NH ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

I can't help on the choosing CPUs part, but I can share my experience with a P4 for a VDR. The thermostatic control fans reduce noise, but are not really silent. I replaced both the power unit to a totally fanless one, and my CPU cooler is Scythe Ninja Rev B, which is totally silent (had a Zahlman AlCu7000 if I remember correctly, before). Then I have an additional 120mm fan running slowly inside the box, but that I cannot hear outside. The most noise right now comes from my Seagate Barracuda hard drives, which are pretty quiet, but still noticeable. Especially one of them which has probably bad bearings. I also tried throttling / underclocking the CPU to reduce heat, but my MB starts an annoying whining noise if I do that, so I could not use that. But my advice, if you really want to reduce noise in a VDR, is to go for fanless choices. If you don't do other processing, any current desktop processor would have enough processing power. For Full HD it could be different, though. yours, Jouni ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
[vdr] Mid range CPU choice
About to step into the deep end and build my first VDR box. In fact 2 of them at the same time both with the exact same specs. All parts are going to be new. New CPU's are a lot more confusing than the simple days of single cores at fixed clockspeeds. My question is what CPU should I chose for good noise reducing , heat reducing solutions. For processing power and cost I am looking at AMD AM2 4000 and Intel Duel Core E2140 and Intel core2 Duo E4400. I am open to other suggestions as long as they can currently be purchased in store. Since the system will be spending 95% of it's time idle I want a CPU that can drop down to the slowest possible clock speed with the least power consumption. I will also be using temperature controlled fans to keep it real quiet and any other ways I can find to drop down power and noise. Advice on the best CPU choice would be much appreciated. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
