Examining BTX

When the BTX form factor was first made public by Intel a few years back they claimed it to be a step forward, an innovative new design which would revolutionize the computer industry. Over a year ago we brought our readers a preview of Intel's reference BTX design.  We explained the layout and the three sizes in which these BTX motherboards would first appear: picoBTX, microBTX, and standard BTX. These sizes follow the same guidelines as those of past form factors with the variation in design and placement of components.

Recently Intel sent out BTX evaluation kits to slowly ease in the news of the release of this new form factor. We were at the edge of our seats as we opened up the brown box with the "Intel" logo on it as we were about to find out just how innovative the BTX design would be. Included in our BTX kit was a microBTX case from AOpen, named the B300, an Intel Pentium 550 CPU, and of course, the long awaited D915GMH microBTX motherboard.

    From here I should think: ">From the picture we see the flow of warm air pulled forward from beyond the VGA card. As it moves towards the front of the case the air flows over the Southbridge and Northbridge passively cooling each chip. We then see from the shades of red the air warms up as it flows through the CPU heatsink then begins to cool as it moves out the front of the case."

    Let's see, a new form factor with new case requirements and STILL no standardized connector for the front Power/Reset/LED's/etc.? I'm all for cooler cases, but a standardized connector for those items is something that should have been implemented years ago.

    #24, who cares since athlons run much cooler and don't need this case form factor.

    I heard a rumor that it wont work with Athlon 64 chips or any type of chip that has the memory controller integrated with the processor, because the distance between the processor and the RAM banks are too far. Anyone confirm this?

    Wow AT is back.

    While I agree that the tweaky enthusiast market doesn't have much to gain at the moment by moving from ATX to BTX, especially as most of them are running A64s or praying-for-death overclocked mobile Athlons, I think there is certainly something to be said for the form-factor. It does seem to be more efficient for cooling than your average ATX(especially for small cases). Even if you are running some PentiumM or a derivative thereof, more efficient is still better. After all, if a given case design can cool a high-end Prescott without deafening its user, it can probably cool a brutally overclocked Pentium M with its fans running at half the speed. For that matter, if the trace length issues aren't actually crippling, I would like to see some A64 motherboards in this format.

    Visualize an office full of MicroBTX Desktop computers. Visualize the women in the office cupping their hands around the heat exhaust... visualize the overclocking tips flowing around the female staff as they strive to increase heat output... visualize the men pouring sweat, desparately trying to duct-tape the front vent to block the hot Intel Air.

    I'm sorry, but any spec that seeks to exhaust hot air out the FRONT of any case, whether it be a desktop, tower or SFF, is just plain STUPID.

    my god, after all these years, they fall back on the packard bell mentality...

    GTMan: Temperatures were certainly taken with the cases closed.

    I wonder if all those temperature measurements were done with the case open? I would think a case designed for efficient air flow would only perform properly (as designed) when fully assembled!!!
