Passively Cooled Computer

October 11, 2008 by Jason Rollette 38 Comments

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

June 23, 2008 by Juan Aguilar 15 Comments

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

June 19, 2008 by Juan Aguilar 5 Comments

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.

Beverage Cooling Contraption Contest

May 28, 2008 by Juan Aguilar 24 Comments

Let’s face it: no one likes warm beer. In the arid August air of Las Vegas, though, it’s difficult to get anything else. To combat this problem, Deviant has hosted a competition the last three years at Defcon called the Beverage Cooling Contraption Contest, or BCCC. We’re not talking about something as simple as a Coleman cooler or even a peltier cooler: the devices entered in this contest have to be able to take a beer from hot to cool and your glass within minutes.
