Wow, didn't realize the extreme Pentium 4 is over $1000. I would wonder if a Athlon 64 is comparable.

Newegg.com has a 1900+ for $50 shipped. Pretty good deal.

Or perhaps this cheap 1700+

I picked up a USB 2.0 box for $29 which supports hard drives or CD-ROMs. Seems okay, not super fast, but suitable for secondary storage or backup. This unit has a small fan that is loud. This case is plastic, and I would imagine any case that is plastic will have to have a fan. If you just want a ha...

Hi Joe, I would note that the Abit motherboard you spec has some FanEQ function, which means it should be able to control fan speed for you. I would probably put that on the case fans. You should read more about that function. I'm not familiar with the Supersilencer, but you might also think about t...

More pipes may be in the works, but it still appears to be limited by the cooling on the other side (the large heatsink). The cooling difference between 1 and 2 pipes was 3°C. I would suspect the temperature decrease diminishes with additional pipes (i.e. a 3rd pipe would likely result in less than ...

Yeah, I blew a fan over the large heatsink. The temp went down 5°C. My conclusion is that 2 pipes seems to be sufficient for Athlon XP chips.

Thanks. I'm investigating various things. I will probably make the base thickness around 1/8" or 1/16". The main issue, from my further testing, seems to indicate that the cooling is better if the "cool" side can dissipate more heat. The heatpipes can pull pretty well, but the other side needs to re...

That's weird, then why have the 12V on the board I wonder.

It may just be a problem with the design?

The Shuttle AN35N I have seems to do this too. Seems a little to do with the mouse and video also, but not sure. I haven't really bothered to test where it's from.

Yeah, I notice the redraw in OpenGL on my ATI is messed up now. Anyways, waiting for next generation of cards, next year I guess, or at least Doom III.

I have brackets for this if you happen to have the larger EAR grommets and bolts that come in the sample kit. Or I suppose you could use screws and washers some how. If you want one let me know, they're gathering rust and dust.

I carted my Sonata to a LAN day yesterday (with 3 HDD's and SLK800) and it really is heavy. Luckily though I have an Antec LANPAL, which made life a heap easier. I must be annoying to get into a room with a bunch of other computers, since most are probably noisy. Although you're probably playing wi...

Besides, "Be Quiet!" is just a modded "ToPower" whis is modded of something. I do not remember what was the original producer, but it was some respected brand... and on THG 21 PSU test topower did quite well, it outputted watts as much it should. This seems to be the one, see the bottom of the page...

As you see, my investements for totally inaudible PC is virtually nothing compared to you guys who spent like zillion to get silent systems. And you do NOT need any fanless heatpipe HS system, because its more reasonable to cool HS with inaudible fan running at 5V. And its cheaper. I agree with tha...

Or, another route- put the whole computer in a different room, with good KVM cables running to your work room. somewhere i've seen a device that took KVM inputs and passed them over a CAT5 as simple IP traffic. or you could just use a silent Xwindows workstation and run VNC to export your windows d...

Well it's possible to get almost everything quiet, from CPU (specialized chassis or other device) to power supply (SilentMaxx) to AGP graphic card (Sapphire stuff), except the hard drive. I'm doing preliminary testing on my own design for that.

Yeah, I wonder what the actual performance is versus a 1700+ (which are pretty darn cheap). An undervolted one can generate a fairly low amount of heat.

The laptop CPUs are sold separately since you are supposed to be able to change them yourself if you have a laptop with a socket.

Why not run a burn program and Prime at the same time?

According to this link, read the bottom. They have various venture capital companies. If you read the link I gave, this is research already done at Stanford, and they are licensing it for commercial use. The research is funded by Intel, Apple, and AMD. What is novel is the pump and micron tunnels. A...

Well I found more information. Here is a link with more technical detail. This sounds like a combination heatpipe and water cooling system. It pumps liquid, which apparently turns to vapor, and then condenses and is pumped back to the hot CPU again. This is very evolutionary/revolutionary. http://me...

Are you saying you don't get any speed control in Speedfan? I have 2, Speed01 and Speed02 that show up for my motherboard and one controls a 80mm L1A. There is no RPM reading for that fan, but I can adjust the speed.

Would heatpipes even be necessary if the cpu were mounted on the underside of the motherboard? That way the cpu could be in direct contact with the massive heatsink (which would be sort of a combination motherboard-tray/side-of-computer-case/heatsink). This is typical of audio power modules, the ho...

Thanks for putting me back in reality Mike. (In hindsight, I'd sure like to edit that post LOL) would it be a good idea to insulate the hot baseplate to prevent any loss to the surroundings? Well I'm not sure, but for now the copper blocks are being cooled a little by the surrounding air, which is ...

....will the heatpipe work effectively if it is bent like an "L", where the bottom is still the hot? Next, why not mount your power supply such that it will suck air over your heatsink. Maybe make some sort of tunnel to aid flow. I think the fewer bends the better. This makes it easier for the liqu...

Anodizing is a process to create a aluminum oxide layer on the surface to help prevent degredation of the surface, at the same time you can add dye to color the aluminum (black, red, blue, etc...). Here is a science project at some high school that explains stuff. Making the surface a black anodize ...

How much better do you suppose a 6 heatpipe cooler would work? Not sure, but there is probably not room to easily place 6 for the socket 462, maybe 4. For the Zalman design, the Pentium 4 has mounting holes that are futher apart from the socket than the AMD. So there is space for 6 pipes, but they ...

Saw this mentioned in a few places.

Thanks everyone for the comments. I did some quick calculations and determined I could get maybe up to 10W more heat dissipation out of the large heatsink by anodizing it. If I get around to it I will try that and check the results. I'm working on a silent/cool hard drive box next, and then the rest...
