Seawater cooled data centers

swac-mauritius

Remember Mauritius from High School geography? We didn’t either, but apparently it’s a small island nation east of the southern tip of Africa. It seems they are trying to develop an industry in eco-friendly data centers. The plan is to use a pipeline to gather cold water from the ocean, run it two miles to the island, and use it as inexpensive cooling. Because rooms packed with servers generate copious amounts of heat it’s easy to see how this can reduce the cost of maintaining a data center.

The thing that struck us here is, how eco-friendly is this? The article mentions that this technology is fairly mature and is already used in several places. With that in mind, isn’t this just another way to raise the temperature of the oceans, or does the environmental savings of not using electricity or gas to produce the cooling offset this?

Foundation cooling

Foundation with Copper

Overclockers are always trying to come up with new, colder, and quieter ways to keep their PCs cool. [gigs] was so dedicated to this, he decided to lay 6 meters of copper pipe to use as a radiator in his new house’s foundation. As of now, the foundation is laid (copper pipes and all), and the forum posts come complete with finished slab pics, though there is no house to speak of yet.

Exersize for a good cause, cold beer

It can sometimes be difficult to decide what items we want to fill space in our homes. Our health is valued highly, as is our ability to consume cold beer. Someone out there must have been thinking of us when they designed this exersize bike that chills your beer. Admittedly, it won’t chill it as fast as some other methods we’ve tried. We also may end up forcing our friends and loved ones to do the actual chilling, but beer tastes better when cooled by slave labor anyway.

Passively cooled computer

This came in on the tipline: [Ville 'Willek' Kyrö] wanted to build a fully passively cooled computer. That means no fans at all. He started with scrap aluminum heatsinks, ripped apart a cpu heatsink to get the copper heat pipes, and began surrounding the boards with heatsinks to form a case. Cooling down the powersupply was the hardest part, as it did not lend itself to the flat surfaces of heatsinks. Any passive case with powerful components will inevitably be huge and heavy; this one weighs over 20 kg. He says, “It might not have been worth it, but it sure was weird watching the computer boot up with no sound at all”.

Antec Skeleton case

Maybe you saw the previous post and thought, “Well, that’s all well and good, but why is such a stylish case being used to ventilate cat feces?” Antec has heard your cries and has created a computer case with all the lovely curves of a litter box and just as much airflow. The Skeleton case has an open frame design with a 250mm fan on top. You mount the motherboard to a sliding tray. The power supply and hard drives are mounted underneath. It’s an interesting idea and easily replicated, but if cooling had been the goal, it would be a lot more enclosed. You can see the case with components installed on TweakTown.

Xbox 360 Modding Case details


If you’ve been wondering about what changes Lian-Li implemented in their commercial XBox 360 casemod called the PC-XB01, they’ve recently updated their product page.

The case does not add any new functions to the console, but it improves its efficiency on several levels. To deal with the noise produced by the DVD drive, they installed sheets of sound insulation foam around the drive, greatly reducing the sound it makes when it spins up. They did even more for temperature control, replacing the standard dual 70mm fans with a single 120mm fan that cools more efficiently and quietly. The case is also larger and features a frontside grate, allowing for vastly improved airflow. Lian-Li designers even left opening in the back for option water tubes in case you want to add a liquid cooling system.

3-digit frequency meter


Flow sensors are useful tools for collecting data on the rate of liquid usage, but they need a device to display the data they collect. This three digit frequency meter was designed by [Turbokeu] to do just that, converting a Swissflow SF800 flow sensor’s square wave signal (similar to fan RPM signals) into an numerical expression of liters per minute on a 3 digit LCD. Fan RPM is

[Turbokeu] provides detailed schematics of different configurations for the frequency meter as well as schematics of the layouts of the two PCBs that are used. Even if you don’t have an immediate use for a frequency meter, his clean and readable schematics are worth a look in their own right. The display is installed on front of a tower case along side a CPU speed display.
