New motherboard design helps cool high-end processors and graphics cards See correction belowGateway Inc. released the specifications Friday for a retail desktop PC based on a new motherboard design that should help cool high-end processors and graphics cards.The company had already provided some details about its first BTX (balanced technology extended) desktop during briefings earlier this month, but it has now formally launched the Gateway 700GR. The BTX motherboard specification is backed by Intel Corp. and designed to replace the ATX standard. The BTX design moves the processor, chipset and memory modules to allow a stream of air to flow through the PC’s chassis. The processor is now located at the front of the motherboard, where cool air first enters the system. The graphics chips have also been rotated so that their exhaust is directed up into the airflow, instead of down into the chassis.Two fans are used to move air, rather than the single fan design used to cool the processor on many ATX motherboard designs. These two fans can move more air than a single fan while turning at a slower speed, which has the additional benefit of reducing the noise produced by the cooling system.The 700GR comes with Intel’s Pentium 4 550 processor, 1GB of memory, a 250GB hard drive, a DVD+/-RW (CD-rewritable) drive and ATI Technologies Inc.’s Radeon X300SE graphics card with 128MB of memory. The suggested retail price is $1,199, without a monitor. It will be available this weekend at retail stores throughout the U.S. Correction: This story originally incorrectly stated where the processor is located in a BTX motherboard design.
