Great review! I've been wondering about this since I saw it in Pine Trail's chipset diagram. IMO, this is a major move made by Intel. What they are doing is allowing systems to be upgraded to HD features, but leaving the base model as low cost as possible without this feature. They purposely left o...

More realistically, the temperature difference is proportional to the inverse of the square root of the velocity. So more like DT ~ 1/ sqrt(v) Various heat transfer relations show this, also the power might not be 1/2 (i.e. square root of v) but some other number less than 1. That shows that as you ...

What you want is a more efficient PS so that when it operates it generates less heat. Also you want one with a quiet fan. Aside from that, you only need enough power to make the system work, which is like a 300-350W unit.

I have a bunch of those 172 mm Comair Rotron fans. They are okay, but not quiet. Although they are probably better than 120mm at full speed. I tried running 24 V ones at 12 V. I think if you have a new one and run it at low voltage it might be reasonably quiet.

Re: source of materials

Do you think it would work if the heatpipe holes were drilled into a solid block of copper? It would work, but you have to be careful about the fit. The two things to ensure are to have good contact pressure and contact area. You will get good contact area by drilling a hole and inserting the pipe ...

I suppose you could just wire up a switch that would kill the power on one drive and leave the other one up, and vice versa. That way the computer would only see one drive. This will work if your motherboard will boot of the drive that it sees (as opposed to only being able to boot off a particular ...

So I'm assuming this dual core design is like jamming two CPUs into one physical part? That would mean the actual performance gain is highly dependent on the software.

This is a complete custom unit from the ground up. I'm designing/building everything. This will be a 4 pipe cooler, or 2 pipe (I guess if want to pay less). It is such that various expansions/changes can be made later.

Well, I'm still a little bit aways, but I'm working on a passive case (surprise) and am trying to gauge interest in this thing.

One of the other things that could cause the transformer to hum is dirty AC on the AC power line.

I saw this occur in some la...
