The wind tunnel computer

Mike Schropp, the self-titled Total Geek who brought us the monstrous-yet-beautiful three-motherboard PC made out of Lego, has gone one better and created a wind tunnel for his new PC.

The PC itself is a beast: An Intel Core i7-3770K clocked at 4.5GHz, with twin Radeon HD 7970 graphics cards. Like Schropp’s Lego workstation, the wind tunnel-cooled computer is used for grid computing — in specific, IBM’s World Community Grid, which uses a worldwide network of computers to create a virtual supercomputer that hopes to cure cancer, AIDS, and find solutions to other areas of medical and scientific research. Where the Lego workstation was oriented towards raw CPU grunt, the IBM World Community Grid software has now been updated to support GPUs — and as you know, for computing tasks that have been specially tailored for massive parallelism, modern GPUs blow CPUs away.

But enough about the specs: What we really care about is that Schropp built a damn wind tunnel to cool his PC.

The basic concept behind a wind tunnel is that you have a large fan at one end, a narrow contraction section in the middle, and then an exhaust after that. The idea is that the large fan creates a sizable breeze (around 2000CFM, with wind speeds of around 14-15 mph), but by passing through the contraction section in the middle the wind speed increases to 26-30 mph. The narrow section is, of course, the perfect place to put a hot computer that’s in desperate need of air cooling.

Building the wind tunnel seems like it was fairly easy: Schropp built the basic shape out of MDF edged with aluminium, with a couple of pieces of polycarbonate forming the see-through window around the PC itself. Schropp then painted the whole thing, added some awesome buttons to the front of the case, put a standard box fan at the entrance to the tunnel (recessed a little, to reduce its noise output), and finally mounted his PC in the middle.

The end result, as you can see, is quite possibly the coolest case mod ever — and, almost as an added bonus, it’s also quite effective as a cooling solution. In testing, Total Geek managed to overclock the CPU to 4.5GHz @ 1.22V, reaching a temperature of 63-65C. With so much extra leeway, he thinks he can hit 4.8GHz — not bad, for an air-cooled not-delidded i7-3770K. GPU-wise, he achieves an overclock from 1000MHz to 1225MHz, with a temperature around 45-50C. Again, Schropp thinks he has the headroom for even higher overclocks (1.3GHz+), but hasn’t yet tried it. While he sadly doesn’t provide any photos, Schropp points out that he actually used smoke to analyze the flow patterns and turbulence around the CPU and GPUs, too.

All told, the wind tunnel PC is currently processing around 8,000 workunits per day, which is about 20 times what a normal IBM World Community Grid member would complete (i.e. Schropp does about 20 days of processing every day). In just over a month, Schropp has donated 750 days of cancer research, or a total of 147,000+ Help Conquer Cancer results. Pretty cool: An awesome-looking computer that’s also helping to save the world.

  1. a perchè con un semplice programma puoi aiutare così tante persone.. e allo stesso tempo non c’è uno spreco energetico lasciato al nulla.. cioè piuttosto che lasciarlo acceso e inattivo…
    Quanti di voi conoscono questo programma?
    se potete accendete la stellina.. è una cosa importante…

  2. sto cercando i dati relativi all’Aids e all’A/H1N1 in ambiente televisivo: quanti servizi sono stati trasmessi nell’ultimo anno? Magari dalla BBC
    Grazie in anticipo xchè non le trovo assolutamente

  3. New York (English New York City), a city of the United States, located in the state of New York. It is the most densely populated city and the main commercial centre, finance and culture of the country. Also known as Big Apple ( “Big Apple”), houses the headquarters of the United Nations, the central bank of the United States (see Federal Reserve System) and the Stock Exchange in New York, one of the main world.

    The metropolis is covers a wide area at the mouth of the Hudson River and East River in Upper New York Bay, an arm of the Atlantic Ocean. It is divided into five districts: Manhattan, the heart of the metropolis, which occupies the island homonym, Queens and Brooklyn, both located on Long Island, Bronx, which is located on land north of Manhattan, and Richmond, Staten Island. Together with centres in neighbouring towns (such as Newark, Jersey city, Yonkers, Elizabeth) form a vast conurbation.

    Economic activity in New York is very diverse, and essentially Basa finance, trade, industry and tourism. Very important node intercontinental communications, following the decentralisation known in recent decades, with the sorting of goods to neighbouring ports of New Jersey in Newark International Airport, has designed its center to business activities and the representation of large multinationals . Particularly developed is advanced in the fields of finance, specialised services, advertising and communications.

    In the district of Lower Manhattan, between Broad Street and Wall Street, are as has been said, the New York Stock Exchange (founded in 1817), the Federal Reserve Bank of the United States and other major financial institutions, banking and exchange . The major television and radio network States, as the main graphics and publishing industries, based in New York. The city is served by three airports: the John Fitzgerald Kennedy and the airport of Newark, intended for international flights, and Fiorello La Guardia, reserved for domestic flights.

    The main point of arrival in past centuries immigrants (which were unloaded and checked at Ellis Island) came originally from Europe and Asia and later from the Caribbean, New York has a very diverse population from the ethnic point of view. In 2000 consisted of the white community, including the so-called “wasp” – see melting pot – (which amounted to 44.7% of the population), Afro-Americans (26.6%), Asian (9.8%) and other ethnic groups, including Hispanics (27%).

    2 URBANISM AND PLACES OF INTEREST

    The island of Manhattan is the heart of New York and its largest tourist attraction. The oldest of lies to the south, and is characterized by districts arranged in an irregular way. North of the 14 th street town-planning, as defined in more recent times, is very regular and geometric, based on a grid of avenues perpendicular (Avenues), distinguished by name or number, which cut the city from north to south , and streets (Streets), broken down by number and placed in the east-west direction.

    It features a panorama of the Manhattan profile of its famous skyscrapers, forming a skyline of the most beautiful and evocative of the world. Among these, we remember the Flatiron Building (1902), the Chrysler Building (1930), Woolworth Building (1913), the Empire State Building (1931), the complex of buildings that is the Rockefeller Center (started in 1931).

    On 11 September 2001 a tragic terrorist attack, which led to about 3,000 victims, destroyed the two twin towers of the World Trade Center (made in 1974 by architect Minoru Yamasaki), which constituted the greatest symbol of American economic power, as well as be among the highest buildings in the world. Pending define the appearance that the area destroyed (known as Ground Zero, “Level Zero”) will take in the future, a massive lighting project called Towers of Light ( “Towers of Light”) was recently put in place for remember the Twin Towers: they are two huge beams of light with three-dimensional effect that reaches a height of 1.6 kilometres and can be seen in a radius of 32 km.

    Among the many bridges that unite citizens districts, the most famous is the Brooklyn Bridge, opened in 1883, linking Manhattan with Brooklyn district, south-east.

    Among the places of worship, the best known are the St. Patrick’s Cathedral (1879), the Cathedral Church of St. John the Divine (begun in 1892) and Temple Emanu-El. The largest park and loved by the New York Central Park is designed by the architects Frederick Law Olmsted and Calvert Vaux, occupies the area between the 59 th and 110 th road since 1850. The Statue of Liberty (1886), one of the most popular symbols of the country, is located on Liberty Island. The vast complex which houses the offices of the United Nations is Midtown Manhattan, along the East River.

    Among the higher education institutions are the most prestigious Columbia University and New York University, while most museums are the Metropolitan Museum of Art (opened in 1880), the Guggenheim Museum (1959) designed by Frank Lloyd Wright, the Whitney Museum of American Art (1966), the Museum of Modern Art (1929) and the Frick Collection (1935).

    The heart of the entertainment district is the area between Broadway and Times Square, which houses more than thirty theaters. Near Central Park is the Lincoln Center for the Performing Arts, a vast complex of buildings that includes the Metropolitan Opera House, the Avery Fisher Hall, home of the Philharmonic-Symphony Society of New York (more commonly New York Philharmonic); New York State Theater, which performs the New York City Ballet, the New York City Opera and Carnegie Hall. Another important concern is the New York Public Library, the city public library.

    Among the neighborhoods of Manhattan are mentioned Chinatown (where from 1850 focused immigration Chinese), Little Italy, SoHo (acronym for ‘South of Houston Street’), once a district of warehouses and factories have become elegant today lofts, ‘ Upper East Side, an exclusive residential area, in Harlem, inhabited mainly by blacks and Hispanics.

    Manhattan is linked to the state of New Jersey since George Washington Bridge and the Holland and Lincoln tunnels. The other districts of the city are far less regularly from the urban point of view, having formed as a result of connect cities and villages originally arose separately. Richmond (on Staten Island) is the least urbanized district, which has, however, started to expand considerably since, in 1964, was connected to the Brooklyn district with Giovanni da Verrazano bridge, one of the longest suspension bridges of the world. Brooklyn and Queens, the most populous districts, are on Long Island and in Manhattan are linked by a series of bridges on East River and the Brooklyn Battery Tunnel. The Bronx, located on the mainland, has a very diverse urban landscape, which includes areas with dilapidated buildings and residential areas with luxury apartments and villas.

    3 HISTORY

    The area around the bay of New York was inhabited for centuries by Native American tribes of irochesi and algonchini. The first European to visit the area was the Italian navigator Giovanni da Verrazzano, which approdò here in 1524. A Dutch expedition led by Henry Hudson explored the river that he later took the name in 1609. In 1624 the Dutch East India Company founded the Western colony of New Netherlands (later became New York). A commercial outpost Dutch (Amsterdam Nieuwe) was founded at the south side of Manhattan in 1626, but it was only years later that there is established a permanent settlement of Europeans.

    In the mid-seventeenth century the continued colonization of the island of Manhattan, and other settlements were built in the areas of the Bronx, Queens, Staten Island and Brooklyn. In 1664 the then governor of the city Pieter Stuyvesant surrendered to the British. After a few years the city was regained by the Dutch, but then finally fell into British hands in 1674.

    The growth in New York was strongly favoured by the trade that occurred along the coasts, rivers and through the ocean. Since the end of the nineteenth century the population increased significantly as a result of massive migration from Europe and China. The expansion of the late-nineteenth city accompanied the construction of major infrastructure, first and foremost the Brooklyn Bridge (1883). In 1898 he was the official division of the city into five districts. In 1904 work was begun for the construction of a complex underground transport system to link the various districts.
