I recently got a Dell T3400 workstation for work. It's got a Q6600, 8gb of DDR2 ram (no idea what kind), and an Nvidia Quadro FX570 video card. I've been very pleased with how it performs and how cool it runs. It loads at about 45c.

I've also found that Dell cases are simply amazing. The cable management is superb and the layout is extremely well thought out.

Mine has two fans. One is a 120mm exhaust fan and the other is either a 92mm or 120mm CPU fan. It looks like it's got a nice tower cooler on it too.

Plastic covered metal blocks more noise than plain metal.

Power saving options (such as EIST) are left enabled, unlike many enthusiasts/gamers.

Components are allowed to run hot as long as temperatures stay within limits. For instance I see many posts in various forums where people freak out when their CPU load temps go above 50șC and idles above 30șC. The fact is that a modern stock clocked CPU can easily run at 80șC or higher, plus Dell does not design their systems to be able to sustain 24 hours of OCCT. They design their systems for "normal" people browsing social networking sites and watching Youtube videos.
My box's Quadro FX570 card isn't amazing, but does have a little fan on it. And the shrouds around the CPU heatsink definitely seem to help channel air and lower noise.

I think I've left the power saving options on, but I can't remember offhand. But, like I mentioned before, it loads at about 45c and stays that way when I do SMP folding.

Overall, I'm really impressed with Dell boxes. Sure they're not for the hardcore enthusiast who wants to do lots of tweaks, but for basic uses and someone who doesn't want to build a rig, they work great!

Is it because they engineer the noise control better when they design their PCs?
Buy an Antec P180 case that was designed from the ground up to be quiet. Most people don't know, but cases have a lot to do with overall sound.

My old dimension e310 only had 1 fan that acted as an intake, CPU, and exhaust fan.

I had a Dell Dimension desktop, there was a large heatsink on the CPU and a 92mm front intake. If I remember correctly the intake fan was labled Sanyo Denki. Its a super quite fan though. And there weren't any exhaust fans at all.

Apple computers are like that too, because it is a closed ecosystem. If you know exactly what motherboard and other components are going into a case, then you can design everything around that. It also helps with assembly, so designing the layout like that probably saves on labor.

Dells are terrible. Their silence is a myth.

Usually in the cooling systems from Dell that I've seen, they run them on the border of overheating. Most of them that I've seen use one fan, on the back of the case, in a duct leading to the CPU heatsink.

Actually, I had a dell dimension 9100 not too long before I found OCN. After being on OCN for awhile and figuring out that dells CANNOT overclock, I bought my current system. When I took my dell apart for the HDD, GPU and CPU I found that dell uses... I can't believe I am about to say this... DELTAS. They must have wicked fan controllers on them though. Seeing as how my CPU ran up to about 70C with ease at 2.4.

Dell loves to run components hot. They use quality fans like deltas, but never put them to real use. I hope that helps.

No, it's more that enthusiasts/overclockers love to run components cold. There is a disconnect between reality and belief.

Belief: OMG my CPU is idling at 35șC and that is too hot.

Reality: That CPU is idling below your body temperature so it will feel cool to the touch.
