Just to drive the point home about low power PSUs, I should point out that the power consumption of most consumer power supplies with no load applied is typically between 10~20W. This is something I've been looking at recently on the test bench. Even the newest revision of the S12 draws 14W with no...

Linus regarding your CPU, noticed you are running an Athlon XP which in my experience is actually quite inefficient at idle. I believe the halt state/disconnect is not properly implemented for all socket A Athlons, if you run a software utility like S2K Disconnect, this will dramatically lower idle ...

Measured Apparent Power draw at the wall outlet using a clamp meter (Voltage x Current). However all PSU are external AC/DC bricks and should have PF close enough to 1 that Watts dissipated should be quite close. ========================== ASUS Pundit P2-AE2 Barebone (Via K8M800) Sempron 3000+ (Idle...

Thanks for pointing this out. I upgraded my BIOS from 0601 to 0702 and the CPU and NB? (Temp3 in Speedfan) temps also dropped 8C!! Now my Opteron 144 is idling (0.8v 1.0Ghz) at a more reasonable 41C and under Prime95 (1.0v 1.8Ghz) 45C using an old Thermaltake SilentPipe heatsink and a 92mm fan insid...

It's hard to compare your Aria to mine temperature/noise-wise, but I'd guess mine is quieter, using fewer fans. I'm pretty certain your setup is quieter with the nice duct work (mine is not quiet enough to be kept on my desk). I like your v2 intake duct idea with the HD mount, do you think there is...

Glad to hear you fixed your problem. Yes I put in a 120mm fan in place of the original PSU. More details on my system here . With a 7800GT it doesn't come close to being a silent system, but it does make for a pretty quiet SFF thanks to the DC/DC PSU. My external AC/DC brick (bought used) does get v...

I found your post with your system details, very nice! I'm surprised you had trouble powering up a P4 2.8 with a 6200, my PW200M paired with an 150W AC/DC brick had no problems running an Opteron 144 (undervolted to 1.0v) with a 7800GT. From SPCR's power dist article their P4 2.8 Northwood system wi...

Don't have any personal experience, but there is a review at SFFTech. The main cooling fan looks similar to the SD11G5 so probably warrants replacement if you need a very quiet system, plus the tiny PSU fans don't look easy to silence either (but you could always put in a DC/DC psu).

I'm confused. In the AMD A64 TDP Poll , I saw different TDPs with seemingly the same CPUs (look at the different TDPs reported for venice 3000+ E6 CPUs). Even if two chips have the exact same part number (ADA3000DAA4BP-Rev E3 Venice for example), their individual TcaseMax/TDP could be different. Th...

I have the PW200M DC/DC converter in an Aria case and didn't experience such problems, either with the 12v dc input hanging in free air or secured onto the PCI bracket. 50% humidity does sound quite dry though, plus carpeting, sounds like static electricity might be your problem. But as for touching...

I have to admit that I haven't paid much attention to TDP in the past, but now that AMD is programming the actual TDP of each individual chip makes it especially interesting for selecting the perfect CPU for a silent PC. Thanks to SPCR's and The Coolest's TcaseMax for bringing our attention to this....

Vik,
If you haven't purchased your system yet (this thread is 4 months old), then the Core Solo Mini is widely available and sounds like it will fit your needs nicely now that Apple has released official (albeit still Beta) install path/drivers for Windows XP.

Only reason I noticed was the X2 4800+ now has a closer power draw to the 3500+ Venice, which is what would be expected if we assume similar TDP means similar power draw at same clock/volts. Since you are on the forums, can you shed any light on how much difference say a 10W increase in CPU power dr...

How are you cooling this chip, I assume it's not in your quiet HTPC rig!? BTW if you still have your Opteron144, would you mind posting it's ...

MikeC, it seems that the CPU power consumption figures have been revised for the idle chart. Although not significant and doesn't change the outcome of the article, I'm curious why this was revised (or am I mistaken)?

Core Duo T2600 on Asus new N4L-VM mATX board reviewed by ExtremeTech here.

Wow impressive, Gigabyte's SPII has the coolest CPU temp of all passive coolers even beating out the lower powered X1300s by 2-4C (and this is after running 3DMark05 for 24 hours in a rig with 2x120mm fans at 5v and a NeoHE). As for the comparison to the fanned card, it should be noted the 6800GT is...

Don't mean to go OT, but Halycon have you tried undervolting your Opteron? Also how hard/easy is it to cool this CPU under load?

Thanks for the heads up on vcore setting. It's been so long since I setup my A7V333 that I forgot about the Vid jumpers. Also from your Fab51 link it shows how to set the CPU bridges so the mb will use the correct Vcore for a mobile chip. As for changing settings on-the-fly from software, I can conf...

I do believe AMD is making low TDP dual-core chips more and more widely available... in the form of the s939 Opterons. So far all posters (except one) on the TCaseMax forum post 35.0W, including Halycon's Opteron 180 on the X2 TDP thread. Although certainly this is not any kind of guarantee, I suspe...

There's no need to wait, it seems that dual core Opterons 165/170 are already shipping with 35.0W TDP rating. Of course there is no guarantee since the TDP is variable, but based on the postings at TCaseMax forums seems most of these chips are 35.0W. Although AM2 may not offer much in terms of silen...

Opteron 144, 939, San Diego, Rev SH8-E4, 57°C, 44.1W (1.400v) MikeC, how about asking posters to include stable undervolt info? Although it does depend on many factors, probably not as variable as overclocking, and might give us a rough idea if TDP has any relation on how well a chip undervolts? 1.0...

1) Regarding thermals, there is no mention of CPU temps in the article. Is it safe to assume this is directly related to the CPU/system power consumption? (Noting that CPUs without the heat spreader - like the Turion probably cool better with their direct contact to the heatsink) If so, at what kin...

SPCR measured 2.3A on 5v and 1.8A on 3.3v rails for the XP2500+ Barton in their Power Distribution aritcle , so this would suggest 6A should be more than sufficient. I briefly tested both a PicoPSU and a PW200M with an ASUS A7V333 and a XPM2600+ underclocked to 166x8 but overvolted to 1.6v (the mb d...

MikeC, wonderful job on publishing an article that involved so much work. I have been anxiously awaiting this article, but have to say it still leaves me with more questions. 1) Regarding thermals, there is no mention of CPU temps in the article. Is it safe to assume this is directly related to the ...

Also on my Pundit, the disc snaps onto the center spindle so can be used in any orientation. However different regions seem to be bundling different drives, so what you get could be different. As for mounting, it should work nicely bolted to a desk, but keep in mind the bolt-able/block-able side has...

Lol, unfortunately we do live in an imperfect world. It does however give a rough idea about their relative cooling potential and at least an attempt to point out which ones are quieter.
