Intel's BTX Form Factor Launched Today

Hack Jandy writes "It's been almost three years in the making, but Intel's BTX form factor finally has some retail products to show for itself. Anandtech has some extremely thorough benchmarks of the new technology and proves that BTX definitely shows an improvement over ATX for the same sized chassis. Anand claims BTX as a design win, "It's obvious why Intel waited for Monday morning to lift their BTX platform - they have a winner on their hands.""

And the point of this is that case manufacturers will more likely want to build cases which work for both, than cases which only work for one of them. Which IMHO would give a form factor which at least allows this a competitive advantage.

      Basically the form factor is the interface between case and motherboard. Especially it doesn't completely fix the motherboard layout. It does, however, fix the positioning of those components which interact with the surrounding, like PCI slots, and with BTX now also the CPU (due to cooling).

      Good point. To add: The new BTX for allows for supposed better cooling because of the arrangement of components on the board. However how much of that extra cooling is due to the new CPU fan orientation.

      Currently most fans are mounted so that air flow is perpendicular to the board. So cases need additional fans to move air parallel to the board (intake and exhaust). There are some CPU fans like the Jet that are mounted the same way the new BTX fans are mounted.

      This isn't new or innovative. Sun has mounted their CPU fans like this for years and even designed their computer so that there is a channel of air for just the CPUs. The Apple G5s and iMac G5 are also designed this way. With BTX there is the parallel flow but no channel so I would not assume that the cooling is as effective.

    You know, ATX systems could be designed well, and cooled appropirately... But absolutely nobody is doing so. Actually I think HP might be, but I don't know if their own workstations completely qualify as ATX.

    Anyhow, the locations for air intake and output are pretty close to standard, but manufacturers aren't taking advantage of it. CPUs and memory aren't put on a motherboard so they will be in-line with the air intake, and being cooled by the rear exhaust fans, or power supply fan. Instead, it's a hack-fest, with a bunch of fans inside the case, blowing hot air in circles, and hoping the case fans are 10xs more massive then they should need to be, to replenish the whole case with cool air every few seconds.

    You can take certain steps on your own, like ducting air from the intake, directly to your CPU, which will cool things down IMMENSELY, but will not help with your RAM, Videocard, etc., which need proper cooling as well.

    If you look at old DEC systems, you'll see they already had the cooling thing down to an art. 3 thermal zones, with very slow, quiet, thermo-controlled 80mm fans. They weren't ATX systems, however, and nobody adapted those ideas to PCs.

    So, while ATX can be pretty effecient, it isn't happening. If it takes a whole new form-factor to force manufacturers to get it done correctly, then I'm certainly willing to switch. BTX isn't ideal, but it's a big step up.

    And you can't say it's only Intel's problem. All processors put off a lot of heat, and with ATX you have to have several very loud fans just to fight against the heat. A better design means cooler, and quieter, whatever processor you use. Sure, maybe Intel will have to ignore the BTX specs on motherboard design where it will hurt them, but that's nothing new. ATX specified that power supply fans should blow air in, not out, but most everyone just ignored that, too.
